Abstract.
Autism now affects a significant number of students in schools. The purpose of this study was to survey special
education teachers who serve students with autism to 1) determine teacher, environmental, and student related characteristics; 2)
identify the self-reported knowledge of effective teaching practices; and 3) identify the self-reported implementation of effective
teaching practices. The study was conducted with special education teachers employed in Virginia using a web-based survey
titled the
Needs Assessment of Special Educators who Serve Students with Autism.
Respondents included 498 special education
teachers with a wide array of qualifications and experience including licensure status, years of teaching and area of endorsement.
Results provide a description of teacher characteristics that directly impact instructional delivery as well as information regarding
self-rated knowledge and implementation of efficacious strategies. Information from this study can be used to improve service
delivery to students with autism by informing policy and directing and enhancing teacher professional development initiatives at
the preservice and inservice levels.
Keywords: ASD, special education teachers, students with autism
1. Introduction
Recent prevalence rates released in 2009 by the Cen-
ters for Disease Control and Prevention (CDC) estimate
that 1 in 110 children have an autism spectrum disorder
(ASD). The increased prevalence has placed substantial
pressure on educational systems, creating a strong need
for teachers qualified to instruct these individuals. The
number of students identified with autism within our
public schools has risen at an approximate rate of 20%
per year since data first became available [45]. Autism
is currently the fastest growing group of students served
through special education [30].
The Individuals with Disabilities Education Act [21]
defines autism as a developmental disability signifi-
cantly affecting verbal and nonverbal communication
and social interaction. Other characteristics are engage-
ment in repetitive activities and stereotyped move-
ments, resistance to change, and unusual responses to
sensory experiences. According to educational law, a
student may be determined to have autism if he/she
has any of the Pervasive Developmental Disorders, also
referenced as autism spectrum disorders, provided edu-
cational performance is adversely impacted.
Those with autism present with unique learning char-
acteristics that differ widely from typical learners as

well as learners with other types of disabilities [23, 37].
According to the National Research Council (NRC)
report,
Educating Children with Autism,
commissioned
by the USDOE Office of Special Education Programs
(OSEP) in 2001, one of the most pressing challenges
for school systems is keeping up with the increase in
personnel needed to provide appropriate services for
students with autism. The challenge involves not only
the quantity of personnel needed to accommodate the
increasing numbers of students, but also involves the
quality of those personnel. Teachers who work with
these students must be knowledgeable of the range of
available educational practices, and must be able to
implement them individually based on student need
[28, 39, 40].
Within the last decade, there has been an expansion
of educational practices demonstrated to be effective
with students with autism [22, 27, 42]. The current
literature published in this field describes a variety of
instructional methods found to be effective. Examples
include behavioral [7, 29], naturalistic teaching [25,
26], joint attention [32], peer-mediated [17], and story-
based interventions [4]. More recently, the National
Autism Center [36] conducted a comprehensive review
of intervention literature and identified eleven strate-
gies that are effective for students with autism. The
NAC published the National Standards Report which
described each intervention in detail and provided illus-
trative examples.
Despite these advancements, there is ongoing con-
cern regarding the quality of educational services for
this population. Educational achievement is low in
comparison to typically developing students, as well
as students from other disability categories [47, 48].
Furthermore, students with autism are not being well-
prepared for adulthood. Postsecondary outcome studies
reveal poor long term outcomes in living arrangements,
employment, and community integration [19, 20,
33].
2. Challenges educating students with autism
Educating students with autism creates a complex set
of issues for educators. Perhaps the most significant is
regarding the range of personnel who provide instruc-
tion to this group. In the Study of Personnel Needs
in Special Education (SPeNSE [8]) special educators
from all teaching assignments reported teaching at least
one student with autism. It is significantly associated
with intellectual disabilities and has an association with
some medical conditions including tuberous sclerosis,
fragile X, cerebral palsy, down syndrome, and epilepsy
[14]. Additionally, comorbidity with mental health con-
ditions including anxiety and depression is common
[16]. Taken collectively, these characteristics nearly
guarantee special educators from multiple backgrounds
will provide services to a student with autism during
their career, regardless of their primary content area
[31]. Given such variation, special education teachers
require preparation to educate this population with such
unique and intensive learning needs.
Preparation of special education teachers has been
fraught with challenges. According to a study by M¨ ller
u
[34], there are few states throughout the country with
licensure in the area of autism, therefore, there is not
a set of guidelines mandating teacher qualities and
requirements. Absence of state licensure in autism
ensures these students are educated by teachers with
different types of certification resulting in variation
of teacher knowledge and skills [41]. This issue is
exacerbated by the recent movement towards noncat-
egorical licensure in special education where teachers
are prepared to instruct students from all disability cat-
egories and do not receive specialized training [24].
How such programs are preparing the range of teachers
touched by autism to serve this group is unknown at this
time.
Educational standards have long been used to out-
line necessary teacher qualities [6]. However, nationally
accepted professional standards that could be used to
guide effective practices for teachers of students with
autism were regrettably absent from the educational
arena until 2009. It was at this time that the Coun-
cil for Exceptional Children (CEC) created standards
that reflect the knowledge, dispositions, and perfor-
mances deemed essential for a well-prepared special
educator. While the development of these standards is
an important step for guiding practice, given the licen-
sure situation described above, educator’s knowledge
of these standards remains unclear.
Professional development activities designed to build
knowledge and skills specific to autism have become
more prevalent in recent years. In cooperation with
OSEP, M¨ ller [35] surveyed state education agencies
u
to determine approaches to personnel preparation in
autism, and found states had increased training efforts
since 1996. In a survey of personnel preparation prac-
tices at colleges and universities, Barnhill, Polloway,
and Sumutka [3] reported 184 higher education insti-
tution programs from 43 states offering personnel

preparation in autism. The nature of these training pro-
grams was highly variable with differences found in
the type, amount, and content of training provided.
How such programs are preparing the range of teachers
touched by autism to serve this group remains uniden-
tified.
3. What is known about teachers of students
with autism
Educators serving these students must possess
autism-specific knowledge and demonstrate methods
that fit into best practice [28, 41]. We place important
responsibilities on these teachers. As a result it is critical
to have a solid understanding of who is teaching stu-
dents with autism as well as their aptitudes. Research
in this area is sparse resulting in restricted information
regarding teacher competency. In 2008, Hess, Morrier,
Heflin, and Ivey surveyed Georgia public school teach-
ers to identify the types of interventions currently being
utilized by those working with students with autism.
Less than one third reported using interventions rated
as evidence based or a promising practice by Simpson
[42]. Fewer than ten percent of the strategies imple-
mented were based upon scientific research. Analysis
revealed the choice of strategies varied by grade level
and classroom type (e.g., general education, special
education).
In a study examining interventions utilized by early
intervention programs in the public schools in Califor-
nia, Stahmer, Collings, and Palinkas, [43] used focus
groups to investigate techniques employed. Results
indicated the use of practices that were research based
as well as many that were not. Additionally, when
evidence-based practices were used, significant mod-
ifications and adaptations were often reported. All
participants noted a lack of adequate training and prepa-
ration for teachers and paraprofessionals as a critical
concern.
we can improve both knowledge and performance and
ultimately, impact student outcomes [49]. Professional
development is needed that provides quality preservice
and inservice training and arms teachers with the skills
needed to effectively serve these students [28].
The purpose of this study was to survey special edu-
cation teachers who serve students with autism in order
to identify characteristics as well as specific knowledge
and practices of teachers who work with this population.
The three specific objectives were as follows:
1) Determine the teacher, environmental, and stu-
dent related characteristics of special education
teachers who serve students with autism.
2) Identify the self-reported knowledge of effective
teaching practices for students with autism.
3) Identify the self-reported implementation of eff-
ective teaching practices for students with autism.
The present study provides a preliminary evaluation
of special education teachers who serve students with
autism in a sample of schools in Virginia. The results
of this study may be used to inform research and edu-
cational efforts. Given that information about special
education teachers who serve students with autism is so
sparse, this preliminary study, despite its limited sample
size, presents information regarding gaps in knowledge
and skills that may inform professional development
for special educators.
5. Method and procedure
A quantitative study using a nonexperimental design
was utilized. A self-report survey was implemented to
answer the research questions.
5.1. Instrument
For the purpose of this study, a survey titled the
Needs
Assessment of Special Educators who Serve Students
with Autism
was created. The survey consisted of a com-
pilation of best and promising practices identified as
critical to address the needs of individuals with autism.
The authors created the survey by synthesizing items
contained in the
Virginia Skill Competencies for Profes-
sionals and Paraprofessionals Supporting Individuals
with Autism Across the Lifespan. The
“Virginia
Skill
Competencies”
were developed by the Virginia Autism
Council (VAC), a state-supported council of autism
experts who work to advance training and educa-
tional opportunities (2004). Its mission is to increase
4. Purpose of the study
The rise in reported numbers of students with autism
in public schools, poor educational outcomes, and an
expansion of knowledge of educational practices that
are effective with this population, has led to a sense
of urgency among educators and parents to ensure
students are provided an appropriate education. It is
essential to determine information about teachers so

knowledge and understanding of autism in the wider
community in order to maximize outcomes for people
with autism.
The
Virginia Skill Competencies
is a list of guide-
lines for educators who serve students with autism.
The
Virginia Skill Competencies
were generated fol-
lowing an examination of current research and previous
efforts to develop educational standards in autism.
Resources used in their development included the
National Research Council report, Educating Children
with Autism [28]; the review of evidence-based prac-
tices compiled by Simpson [42]; the examination of
effective educational practices by Iovannone et al. [22],
the interventions and treatments text by Simpson, de
Boer-Oh, Griswold, Smith Myles, Byrd, Ganz, et al.
(2005); the
Iowa Best Practice Guidelines;
and the
Autism Program Quality Indicators.
The
Virginia Skill Competencies
outlines six key
areas of proficiency, each with equal importance:
1) General autism: Addresses basic information re-
garding the diagnosis and characteristics of
autism;
2) Individualization and support strategies: Addres-
ses appropriate assessment and program planning
for individuals with autism;
3) Communication: Focuses on practices and skills
needed to improve communication and language;
4) Social skills: Focuses on practices and skills
needed to improve social functioning;
5) Behavior: focuses on determining messages com-
municated by behaviors and developing positive
plans to teach new skills and reduce problem
behavior; and
6) Sensory motor development: Addresses sensory
motor supports that are needed by some individ-
uals with autism.
Under each area, there are two types of competencies:
knowledge based and specialized skills. Knowl-
edge based competencies depict particular knowledge
needed to serve individuals with autism, while spe-
cialized skills outline particular aptitudes professionals
should demonstrate.
5.2. Survey development
The Needs Assessment of Special Educators who
Serve Students with Autism
was created by identify-
ing items from the
Virginia Skill Competencies.
Three
specific steps were used to guide the development of
instrumentation. The first step was the generation and
selection of questionnaire items and ratings. This survey
contained 32 of the
Virginia Skill Competencies,
and
included items from each of the six proficiency areas.
There were a total of eight questions that comprised
the proficiency area General Autism. For this area, par-
ticipants were asked to rate their level of knowledge.
These questions contained knowledge-based content
that could not actively be implemented in the class-
room. For all other proficiency areas, participants rated
their level of knowledge and implementation as these
questions specifically asked about strategies and prac-
tices. The number of questions posed and examples for
each proficiency area are provided in Table 1.
Participants provided a self-rating of their knowl-
edge and implementation of practices using a five-point
Likert scale. When rating current level of knowl-
edge, one represented “little knowledge” and five “very
knowledgeable”. When rating current level of imple-
mentation, one represented “rarely implemented” and
five “frequently implemented”.
The second step consisted of a review by a panel of
experts to ensure validity. Experts in the field of autism
intervention reviewed the survey and provided feed-
back on the content and format. Changes were made
accordingly.
The third step was completion of a pilot test to ensure
validity and reliability. Participants in the pilot included
former special education teachers as well as private
school teachers of students with autism. The pilot group
was asked to take the survey and comment on the
following questions [13]: (a) Are instructions clearly
written? (b) Are questions easy to understand? (c) Are
response options easy to understand and exhaustive?
(d) Is privacy of the responses understood? and (d) Are
there any suggestions for clarifying instructions, ques-
tions, or response options? Additionally, each question
was evaluated ensuring variability among responses.
Modifications were incorporated into the survey. After
this revision, the experts had an additional opportunity
to review the altered survey.
5.3. Participants
The participants for this study were special education
teachers employed in a public school in the Virginia
Department of Education Region I. Special education
teachers were eligible to participate if they taught at
least one student with autism in the five years preceding
distribution of the survey. To qualify as having taught a
student with autism, instruction must have been deliv-
ered to the student for a minimum of 25% of the school

as outlined in IDEA [21].
The Virginia Department of Education Region I is
comprised of 15 school divisions and is located in
central Virginia. The divisions contained within are
geographically diverse. The USDOE, Institute of Edu-
cation Sciences National Center for Education Statistics
(IES NCES) provides the geographical status of each
school division using the classifications of city, suburb,
town, and rural. According to this source, two of the
divisions are classified as city, four are suburb, while
nine are rural. Cities and counties in this region make
up approximately 15% of Virginia’s total population
(United States Department of Agriculture Economic
Research Service [44]).
There are a large number of students with autism
served in this Region. During the last five years,
13–15% of the population of students with autism in the
state of Virginia have been served in Region I schools.
At the time of this survey, region one had 889 of the
6,753 students served under the category of autism in
the state. In the rural divisions, child counts of students
served under the category of autism ranged from 3–28.
For the suburban divisions, counts ranged from 12–314,
and for the two city divisions, counts were 6 and 87.
5.4. Procedure
Special education teachers were provided three
weeks to complete the Web based survey. All sur-
vey information was sent electronically to the teachers
through school email. Electronic correspondence pro-
vided a link to the survey. Participants could complete
the survey at their leisure at any point during the three
week period.
Permission was granted by the division’s special
education director or by their research department.
Attached to the email message was a detailed cover
letter explaining the study. The letter described the pur-

pose, criteria for participation, the individual’s rights
to decline participation, confidentiality assurance mea-
sures, the website to access the survey, and detailed
instructions for completion.
Potentially, all special education teachers who
worked in Region I at the time of distribution had access
to this survey. However, the sample was limited to those
teachers who received the survey link and subsequently
responded. Follow-up procedures were used to enhance
participant response to the survey which included dis-
bursement of reminder e-mails one week prior to the
termination of data collection and again three days prior
to termination.
There was no direct interaction between participants
and researchers. Surveys were completed anonymously
so there was no link between names and responses.
Additionally, the name of the school division where
the participant taught was not included on the form
to further prevent linking responses to participants.
Information was stored through a secure web server
administered by the Virginia Commonwealth Univer-
sity Office of Technology Services.
The survey was administered and data collected
using SurveyMonkey. Data was exported and analyzed
using a statistical software package for Social Sciences
(SPSS 14.0). All data were aggregated based on cat-
egories and were reviewed for accuracy, completion,
and presence of univariate and multivariate outliers.
Reliability was evaluated to determine the internal
consistency of scores obtained within each of the six
proficiency areas of the
Virginia Skill Competencies.
6. Results
6.1. Response rate
There were 2,334 special education teachers
employed in the 15 participating divisions at the time of
the survey. A total of 498 surveys were completed and
used for analysis. This equates to 21.3% of special edu-
cation teachers from the participating school divisions.
Variation in the school division’s response rate ranged
from 11.1 to 57.1%. Eighty-six surveys (14.5%) were
not included in the analysis due to incomplete infor-
mation. Table 2 provides detailed information about
survey responses including the total from each school
division and the percentage of special education teach-
ers who completed a survey. Of these teachers 18.0%
were employed in a city division, 56.6% in a suburban
division, and 25.4% in a rural division.
It is unknown how many of the special education
teachers in the region served a student with autism
and were eligible to participate in this study. Studies
regarding estimates of teachers who serve this group are
sparse. The only known study available is from 2001.
Using the results from Carlson et al. (SPeNSE) it was
estimated that 438 of the 2,334 special education teach-
ers in the participating school divisions taught a student
with autism at the time of the survey. Given that 498
teachers responded to the survey, and given the age of
the SPeNSE study, obviously many more special educa-
tors taught this group. However, other means to provide
an exact count were not available.

6.2. Teacher characteristics
The teacher characteristics fell into one of three
categories: teacher related characteristics, environment
related characteristics, and student related character-
istics. Table 3 contains a description of participants
according to teacher related characteristics. The major-
ity of special education teachers who completed the
survey were fully licensed with 86.7% falling into this
group. In Virginia, there is no licensure in autism. At
the time of this study, Virginia operated under a special
education system of categorical licensure. Categories
are listed in Table 3. Participants were asked to choose
their primary area of endorsement. Each of the seven
endorsements recognized by the Virginia Department
of Education (VDOE) at the time of the survey was
reported by teachers with full or provisional licensure.
Learning disabilities and mental retardation were the
most commonly reported with nearly one quarter of
special education teachers endorsed in either category.
Hearing impairments and vision impairments were the
least commonly reported areas. A total of 12 (2.4%)
participants reported an endorsement of other. It is not
known what other endorsements teachers held, as this
information was not collected. On the survey, partici-
pants were asked to provide number of years they had
been teaching inclusive of the school year in progress.
Years of teaching experience ranged from 1 to 36 years
with 11.99 being the mean and a standard deviation

nine years or less. These data were analyzed and cate-
gorized into four groups containing an approximately
equal number of teachers: 4 or less years, 5–9 years,
10–16 years, 17 or more years.
Information describing the demographics related to
the teaching environment is summarized in Table 4. The
majority of participants were from a suburban school
division, while nearly a third from a rural division.
The grade or educational level taught was captured.
The majority, with 42.8%, taught elementary aged stu-
dents. The lowest percentage of participants taught
early childhood with 9.1%, while the balance taught
middle and high school students. Teachers were asked
to indicate the classroom setting that best describes
where they teach. Participants reported working in a
variety of settings. A self-contained classroom for stu-
dents with a disability category other than autism was
the most commonly reported, while a general education
classroom as a consultative or collaborative teacher was
the second most common.
Table 5 provides a description of participants accord-
ing to student related characteristics. Teachers were
asked to report the number of students taught in the
past five years. The number ranged from 1–65, with
7.29 being the mean and a standard deviation of 8.04.
These data were analyzed and categorized into three
groups containing an equitable number of teachers. The
groups delineated teachers who have taught a small (3
or less), moderate (4–9), and large (10 or more) number
of students with autism.

need and capabilities. First, teachers were asked to
indicate the percentage of students believed to have
an intellectual disability and requiring significant lev-
els of support. These students were defined as those
with non-verbal or minimal verbal language, seem-
ingly below normal cognitive functioning and adaptive
behavior. Teachers were also asked to indicate the per-
centage of students believed to have average or above
average intellectual ability and requiring less support.
Students in this group were defined as those with flu-
ent verbal language and seemingly normal cognitive
functioning and adaptive behavior. This group included
students who were diagnosed with Asperger’s Disor-
der or pervasive developmental disorder not otherwise
specified. These data were arranged into the following
groups: majority of students with an intellectual dis-
ability (61–100% of students served had an intellectual
disability), majority of students without an intellec-
tual disability (61–100% of students served did not
have an intellectual disability), and comparable number
of students with and without an intellectual disabil-
ity (between 39–60% of students served from either
category). The greatest number of teachers reported
teaching students without an intellectual disability,
while the fewest reported teaching those with an intel-
lectual disability.
Teachers were asked to indicate the percentage of
students they had taught who were primarily educated
in a special education or general education classroom.
Based on the results, these data were arranged into
three groups: majority of students educated in a special
education classroom (66–100% of students educated in
special education classroom), majority of students edu-
cated in a general education classroom (66–100% of
students educated in general education classroom), and
comparable number of students educated in a special
and general education classroom (34–65% of students
educated in either setting). The greatest number of
teachers reported teaching a majority of students edu-
cated in a special education classroom, with nearly half
teaching this group.
6.3. Self-reported knowledge
Data analysis required the use of descriptive statistics
(total number of participants, mean, standard deviation,
and range) to determine the self-reported knowledge
and implementation practices of special education
teachers. Descriptive statistics were calculated for the
total score for Region I as well as each of the six profi-
ciency areas.
Information describing teachers’ self-reported
knowledge is found in Table 6. This table summarizes
the responses for total knowledge as well as knowledge

Strategies, Communication, Social Skills, Behavior,
and Sensory Motor Development. Responses are
provided in descending order to indicate the greatest
to least amount of knowledge reported in the six
areas. The mean for total knowledge was 2.89 with a
standard deviation of 0.87. This demonstrated a low
to intermediate mean level of knowledge. Participants
reported the greatest knowledge in General Autism, and
the least knowledge in Sensory Motor Development
followed by Social Skills.
6.4. Self-reported implementation of practices
Table 7 provides a summary of the self-reported
implementation practices. A summary for the total
score is provided, as well as the proficiency areas
of Individualization and Support Strategies, Commu-
nication, Social Skills, Behavior, and Sensory Motor
Development. The proficiency area General Autism
was not included in this analysis, as this area was com-
prised of knowledge-based content that could not be
actively implemented in the classroom. Responses in
the table are provided in descending order to indicate
the greatest to least amount of implementation. The
mean score for total implementation was 2.55 with a
standard deviation of 0.89. This demonstrated a low
to intermediate level of implementation. Participants
reported implementing Individualization and Support
Strategies the most often. They reported implementing
practices related to Social Skills followed closely by
Sensory Motor Development the least often.
7. Discussion
The purpose of this study was to ascertain infor-
mation about special education teachers who serve
students with autism. It is critical to have a solid under-
standing of who is teaching these students as well as
their aptitudes. Research in this area is sparse resulting
in restricted information regarding teacher competency.
The present study provides a preliminary evaluation
of special education teachers who serve students with
autism in a sample of schools in Virginia.
This study provides a description of germane teacher
characteristics that directly impact instructional deliv-
ery as well as information regarding actual knowledge
and implementation of efficacious strategies. Results
can be used to improve service delivery by directing
and enhancing teacher professional development ini-
tiatives at the preservice and inservice levels. Results
may also be used to inform future research. There are
several important observations that can be made based
on the data. These observations are summarized below.
1) Special education teachers who serve students
with autism present with a wide array of quali-
fications and experience. Teachers, regardless of
area of endorsement, teach students with autism.
All seven areas of endorsement recognized by
VDOE were represented in this study. Endorse-
ments in learning disabilities, mental retardation,
and emotional disturbance were the most fre-
quently reported. However, also noteworthy were
the number of participants with endorsements in
early childhood special education or severe dis-
abilities. This finding is critical, as students with
autism present with needs vastly different from
those with other disabilities [23, 28]. Distinc-
tive supports and intervention are required given
that cognitive ability is interwoven with social
and communication limitations and the presence
of stereotypical patterns of behavior and sensory
processing difficulties interfere with learning [2].
Total years of teaching experience varied dra-
matically with a fairly even distribution ranging
from one to 36 years. This demonstrates that large
numbers of special educators just entering the
field are serving this group. It also shows that
seasoned teachers are involved. These teachers
may have very different professional develop-
ment needs as their experience with students with
autism as well as training opportunities likely dif-
fer tremendously.
Special education teachers provide service
delivery to a sizable number of students with
autism. These students demonstrate a wide-range
of cognitive, verbal, and adaptive ability. The

D. Hendricks / Teachers serving students with autism
majority of teachers reported having taught mod-
erate to large numbers of students with autism in
the past five years with approximately one quarter
having taught ten or more. Autism is consid-
ered a spectrum disorder that ranges from severe
to milder forms [1, 37]. Predictably, such diver-
sity among student ability is reported. Teachers
served students ranging from those with mini-
mal or no verbal language and seemingly below
normal cognitive functioning to students with
fluent verbal language and normal cognitive func-
tioning. Over one third of teachers had taught
a comparable number of students on opposite
ends of the spectrum. This is of particular inter-
est given the challenges educators face due to
the multidimensional nature of the disability. The
wide range of cognitive abilities and verbal skills
affect the knowledge and competencies required
[28]. What’s more, the majority of participants
(approximately 80%) reported having served stu-
dents who are considered to have normal cognitive
abilities and are high functioning, requiring spe-
cial practices that address communication and
social needs and enable academic success.
2) Special education teachers provide service deliv-
ery to students with autism in a variety of
educational environments. Teachers from all
grades reported serving this group. Approxi-
mately half taught students in early childhood
and elementary school while the other half were
middle and high school teachers. Obviously, stu-
dents with autism do age and cross all grade levels
impacting teachers regardless of educational level
taught.
Well over half of participants served students
in a special education self-contained classroom.
For those teachers, only one quarter taught in
a class specific to students with autism, while
most taught these students in classrooms designed
for other types of disabilities or multiple dis-
abilities. A quarter of teachers reported serving
students primarily in the general education class-
room. Noteworthy, is the number of teachers who
served students in both a special education and
general education setting. These teachers had stu-
dents on their case load who received the majority
of their educational services in two very different
educational environments.
3) Special education teachers who serve students
with autism have low to intermediate levels of
knowledge of autism and effective instructional
practices. The total mean score for self-reported
knowledge was in the low range. Teachers do
not possess a moderate or high level of knowl-
edge in any of the six proficiency areas. General
Autism received the highest score and fell just
within the intermediate level of knowledge. Com-
munication, Social Skills, and Sensory Motor
were the lowest scored. While teachers reported
higher levels of knowledge of autism character-
istics, knowledge of strategies to address skill
development in fundamental areas of need was
lacking. This is a distressing result considering
the defining characteristics of the disorder and the
tremendous impact on the student with autism.
4) Special education teachers who serve students
with autism have low to intermediate levels of
implementation of effective teaching practices.
The total mean score for self-reported implemen-
tation was in the low range. Mean implementation
scores failed to reach an intermediate level for any
of the six proficiency areas, including Individu-
alization and Support Strategies which received
the highest rating. These results are especially
problematic since Individualization and Sup-
port Strategies outlined appropriate assessment,
program planning, and evaluation methods. Com-
munication, Social Skills and Sensory Motor were
reported to have the lowest level of implemen-
tation. This is not surprising given these were
the lowest rated areas of knowledge. All students
with autism will benefit from an array of educa-
tional supports and practices to address primary,
secondary and learning characteristics. Therefore,
special education teachers, regardless of the stu-
dents served, must be well-versed in a variety of
strategies that effect change. It is evident from
these data that special education teachers are not
implementing evidence based strategies for stu-
dents with autism at a satisfactory level.
8. Implications
The implications from this study are important to
state policy makers, school divisions, and institutes of
higher education (IHE) as results can impact teacher
qualifications and guide professional development ini-
tiatives that will ensure current and future special
education teachers are effectively able to teach students
with autism. These findings are especially important
given the rise in prevalence. The fact that this population

D. Hendricks / Teachers serving students with autism
47
of students is now estimated to comprise approximately
one percent of school age children is compelling (CDC,
2010).
As professional development initiatives are designed
and implemented, there are several important consider-
ations extrapolated from this research. First, it is critical
to ensure all special education teachers, regardless of
endorsement area are prepared to teach this group. Stu-
dents with autism will differ tremendously from others
and teachers must be knowledgeable of the characteris-
tics and impact on learning. They must be familiar with
research and theory regarding best practices to address
academic social, communication, behavior, sensory,
and motor needs.
Second, special education teachers must be ade-
quately prepared to address the entire array of learning
needs of students served. Teachers are faced with a
huge task given the heterogeneity. They must be mas-
terful in a range of strategies including applied behavior
analysis, natural environment teaching, assistive tech-
nology, augmentative and alternative communication,
as well as assessment and data collection and must be
able to apply strategies based on student need [28, 36].
For those students considered to have normal cognitive
abilities, their academic profile presents with a num-
ber of unique challenges, yet they are often expected to
meet the same academic standards as their neuro-typical
peers [38]. This requires special practices that address
communication and social needs and enable academic
success.
Third, special education teachers must know how to
provide effective instruction as the student ages and
develops. Teachers, regardless of grade taught, will
serve these students. Practices employed as well as
specific curriculum components will vary as the stu-
dent ages and reaches higher grade levels. Professional
development, therefore, must help teachers learn how to
meet the ever changing needs of these students and must
ensure appropriate preparation for adulthood including
skills related to social functioning and self-regulation
that are so critical in the adult world.
Finally, the finding related to placement is an impor-
tant one to consider. While most participants are
serving students in self-contained classrooms, there
is a significant number serving students additionally
or exclusively in the general education environment.
Preparation is to include training on differential deliv-
ery of strategies and supports based on student need as
well as the learning environment. Practices are mod-
ified according to the environment in many cases to
maximize learning and to facilitate peer interaction and
social inclusion. Further, the ability to implement evi-
dence based practices in a variety of educational settings
will enhance opportunities for students. It could be
that students who require intensive supports and who
fail to receive those supports would present increased
instructional and behavioral challenges, resulting in an
increased use of self contained placement. Thus, in
order to increase these students access to general educa-
tion environments, it is imperative to increase the skills
of their teachers.
At the preservice level of teacher preparation, there
is a demonstrated need for increased content related to
autism as well as scientifically based practices across all
teacher education programs. Teachers from all certifica-
tion categories recognized by the VDOE taught students
with autism. Further neophytes taught students upon
entry into the field. Given the rise in prevalence, this
is likely to be the case for the foreseeable future. Thus
all special education teachers entering the field need to
be prepared and receive instruction on those strategies
currently deemed evidence based. However, instruction
should also be provided in identifying practices through
research findings and integrating such knowledge with
the unique characteristics of the student, values and
preferences of families, and data-based decision mak-
ing [36]. This can and should be addressed through
multiple levels of preservice instruction for special
education teachers including coursework specifically
centering on autism, integration of content into current
teacher preparation courses, as well as opportunities for
hands-on experience with students with autism through
practicums and student teaching.
In service professional development for special edu-
cation teachers is a critical consideration. Teachers will
not enter the educational arena armed with all knowl-
edge and skills needed to effectively serve this group
of heterogeneous students. Additionally, research on
autism and evidence based strategies is growing rapidly.
Thus, ongoing and intensive educational opportuni-
ties for teachers are needed. The quantity, quality and
structure of professional development activities require
careful consideration. Common training strategies con-
sist of workshops and large group presentations. These
methods are often ineffective. According to Gersten,
Vaughn, Deshler, and Schiller [15], special education
teachers’ knowledge of research based strategies only
sporadically finds its way into educational practice.
For educational performance to improve, teachers must
infuse such knowledge into current practice through
training that involves supervision, feedback, and con-
sultation [36]. Teachers in this study reported lower

implementation than knowledge, supporting the need
for training and development methods that will result
in higher rates of implementation of substantiated prac-
tices.
These findings also beg the question regarding spe-
cialized teacher licensure in autism. It is clear that
students with autism require specialized environmental
and instructional practices [20]. Barnhill et al. (2010)
reported that a number of IHEs now offer preparation
programs related to this disability. Programs differed
significantly. Only four IHEs offered a state endorse-
ment leading to full licensure while the most commonly
reported program was a certificate in autism. Licensure
is determined in each state individually and IHEs can
only offer licensure programs allowed by their state.
This leaves IHEs to develop programs on their own,
resulting in tremendous variability among the quan-
tity and quality of courses. By offering licensure in
autism, state agencies have the ability to improve con-
sistency of IHE programming, increase availability, and
ensure provision of evidence based research coupled
with opportunities for practice. At the very least, state
agencies not offering autism licensure should clearly
define minimum standards for personnel qualifications
and experience [28]. This would work towards ensur-
ing teachers are equipped with requisite knowledge and
skills needed to teach effectively.
the sample was a true representation, as it was not
known exactly how many special education teachers
employed in the Region I area had served a student
with autism. This survey was dependent on voluntary
participation and research using voluntary participation
typically yields response rates well below one hun-
dred percent [5]. The personal and professional interests
of the teachers may have resulted in response bias.
Comley [10] noted response rates are impacted by the
participant’s interest or relevance in the survey. Spe-
cial education teachers who were motivated to express
their knowledge of autism were more likely to respond.
These limitations point to the need for more research in
this area.
10. Conclusion
The rise in reported numbers of students with autism
in public schools, poor educational outcomes, and an
expansion of knowledge of educational practices effec-
tive with this population has led to a sense of urgency
among educators and parents to ensure students are
provided an appropriate education. As a result, it has
become increasingly necessary to ensure special edu-
cation teachers are adequately prepared and possess
knowledge and skills needed to promote change.
To date, little research has evaluated qualities of spe-
cial education teachers who serve students with autism.
This study sought to lessen this gap by providing a
description of special education teachers and an eval-
uation of knowledge and implementation of evidence
based practices. The results of this study provide base-
line data that have implications for development and
refinement of personnel requirements as well as training
initiatives. The success of students with autism depends
on improving efforts that ensure current and future
special education teachers provide consistent programs
based on substantiated methods.
9. Limitations
This research study provides a unique examination
of special education teachers who serve students with
autism. The lack of research investigating the spe-
cific knowledge and implementation practices of these
teachers suggests findings are preliminary and provide
a baseline for generation of future research.
Limitations with this study have been identified. The
methodology employed created limited generalization
of the findings. The study was regional in focus and gen-
eralizations to special education teachers outside of the
Region I area should be considered with caution. Each
county and city in Region I is considered to be near a
metropolitan area [44]. While the size of the counties
and cities vary, the proximity to metropolitan areas may
have provided a unique population, resulting in partic-
ipants who are not indicative of all special education
teachers who teach students with autism.
There is a limited amount of information known
about the population. It was not possible to determine
the actual size of the population and to determine if
