The National Association of School Psychologists (NASP) endorses the use of evidence-based assessment (EBA), and guidelines and standards are available for best practices in ASD for school psychologists (Campbell, Ruble, & Hammond, 2014; Wilkinson, 2017; Esler & Ruble, 2015; Filipek et al., 1999; Ozonoff, Goodlin-Jones, & Solomon, 2005). Elements of EBA in ASD include the following: (a) the use of psychometrically sound assessments for ASD; (b) a developmental perspective that characterizes abilities over the lifespan; (c) assessment of core areas of impairment associated with ASD; and (d) the use of information from multiple sources, including direct and indirect observation from parents and teachers to better estimate skills beyond those that may be dependent on characteristics of the environment
Although school
psychologists are often called on to assume a leadership role in evaluating,
identifying, and providing interventions for students with ASD in our schools,
there is little research to show how closely school psychologists align their
practices with the parameters of best practice. Due to the increase in the
number of children receiving special education services under the
classification of autism, research is needed regarding the preparedness of
school psychologists and schools to address the needs of children with ASD.
Surveys
Although there is a paucity of research focusing on
the delivery of school psychological services for students with ASD, there are
several national and state-wide surveys which provide exploratory information
regarding school psychologists’ level of knowledge in the area of autism
assessment and intervention; assessment methods, measures, and techniques; level
of training; and perceived level of preparation and confidence.
- Aiello & Ruble (2011, 2017) investigated school psychologists’
knowledge and skills in identifying, evaluating, and providing
interventions for students with ASD. A total of 402 participants from 50
states completed their survey. Results indicated that despite a limited
amount of training received during their graduate education or pre-service
training for working with the autism population, most school
psychologists’ self-reported knowledge of ASD was in the expected
direction for agreement. However, there were gaps in knowledge regarding
the differences between emotional and behavioral disorders and autism,
developmental delays and autism, and special education eligibility versus
DSM diagnoses that need to be addressed through more training. The
survey also indicated the need for additional training opportunities in
providing interventions, strategies, and supports for students with autism
in the following areas: developing family-centered educational plans;
training peer mentors; and translating assessment information into
teaching goals and activities.
- Rasmussen (2009) also completed a national survey of school
psychologists to determine their level of knowledge in the area of autism
assessment; level of training; and perceived preparation and confidence in
providing services to children with ASD. Results indicated that training
positively affected school psychologists’ knowledge about autism; their
levels of involvement with students with autism; and their perceived
levels of preparation to work with this population. Of the 662
participants, the majority accurately identified diagnostic features and true
and false statements about autism, suggesting an adequate understanding of
autism. Participants with more training reported an increased level of
involvement on multidisciplinary teams and an ability to diagnose autism
when compared to those with less training. Brief rating scales were among
the most commonly used instruments, while more comprehensive and robust
instruments were among the least-often employed, suggesting school
psychologists are either not trained or are limited in the time and
resources needed to use evidence-based instruments. Participants felt more
prepared to provide consultation and assessment services and less prepared
to provide interventions. Although a majority (96.5%) of the respondents
reported they had attended workshop presentations or in-service trainings
on autism, less than half (43.7%) had completed formal course work in
autism in their training program and less than one third (32.3%) had
internship or residency experience with autism. These data and previous
research suggest school psychologists need more formal training and
experience in meeting the needs of individuals identified with autism.
- Singer (2008) surveyed 199 school psychologists regarding the
frequency with which they were called upon to provide services to students
with an autism spectrum disorder (ASD); services they actually provided to
those students; and their perceptions of the training and experience they
had pertaining to the assessment and treatment of ASD. Additionally, the study
surveyed 72 graduate programs in school psychology to determine the extent
to which these programs prepared new school psychologists to work with
children who have ASD. A majority of respondents (64%) reported using only
brief screening instruments to identify students. Although able to
identify the “red flag” indicators of ASD, very few school psychologists perceived
their training as adequate. Only 12.6 % of respondents indicated that they
had sufficient coursework in ASD and only 21% indicated that they had
sufficient practicum experience. Just 15% indicated that their overall
training with ASD was “completely adequate.” Only 5 of the 72 (16.9%)
school psychology programs surveyed offered a specific course in ASD; most
indicating that the topic was addressed in other courses. According to the
author, the survey data suggest that school psychologists lack adequate knowledge
about evidence-based instruments and procedures available to screen,
assess, and intervene for ASD.
- Pearson (2008) surveyed a group of Pennsylvania school
psychologists regarding their training, knowledge and evaluation practices
when assessing and diagnosing ASD. The aim of the study was to determine
the extent to which school psychologists are prepared to meet the rapidly
increasing demand for using best practice procedures when assessing and
diagnosing ASD. An electronic survey was sent to 1,159 certified school psychologists
with 243 completed surveys returned. Survey results found the majority of
respondents indicated that they rely on the use of brief screening
instruments and do not use or recommend "gold standard"
instruments with students suspected of having ASD. Only 32.2% of the
respondents reported they were very much prepared to recommend an IDEA
classification of Autism. Less than 5% of the school psychologists
surveyed received formal training in ASD at graduate institutions or
internships. The overwhelming majority of school psychologists surveyed
believed there is a need for
more training for school psychologists concerning the characteristics of
ASD, best practice in the assessment of ASD, and differentiating ASD from
other developmental or coexisting disorders.
- Small (2012) used an online survey of 100 members of the
Massachusetts School Psychology Association (MSPA) to obtain information
pertaining to demographics, participants' experiences with the ASD
population, participants' knowledge of ASD, as well as their use,
competency, and feelings of usefulness of various assessment techniques
and treatments/interventions. The results indicated that overall, school
psychologists demonstrated adequate knowledge of ASD, felt competent conducting
assessments, and reported that the assessment tools were useful. School
psychologists spent less time on treatment/intervention and while they
considered many of the treatments/interventions helpful, they did not feel
competent implementing them. The results suggest that school psychologists
need more training in ASD, especially regarding treatments/interventions,
at the pre-service level through graduate school training and experiences
(e.g., practica and internships), as well as at the practitioner level
through professional development opportunities.
Implications
As more and more children are being identified with
ASD and placed in general education classrooms, school psychologists will play
an ever increasingly important role in identification and intervention, as well
as offer support, information, consultation, and recommendations to teachers,
school personnel, administration, and families. Therefore, it is essential that
they be knowledgeable about evidence-based assessment and intervention
strategies for this population of students. Despite the limitations inherent in survey
research, the data from these studies suggest that school psychologists are not
adequately prepared to provide evidence-based assessment and intervention
services to children with ASD. The survey research illustrates a
significant discrepancy between best practice (evidence-based) parameters and
reality when it comes to the practice of school psychology and ASD in the
schools (Aiello & Ruble, 2017).
Federal statutes require that
school districts ensure that comprehensive, individualized evaluations are
completed by school professionals who have knowledge, experience, and expertise
in ASD. Although surveys indicate sufficient knowledge of the signs and
symptoms associated with ASD, there is
a critical need for school psychologists to be trained and develop competency
in evidence-based assessment and identification practices with children who
have or may have an ASD. For example, Aiello & Ruble (2017) found a majority of survey respondents reported
using brief screening measures such the GARS and/or GADS in assessment and
identification, both of which are not recommended for use in decision-making
(Brock, 2004; Norris, M., & Lecavalier, 2010; Pandolfi, Magyar & Dill, 2010; Wilkinson, 2010, 2017). In contrast,
evidence-based tools such as the ADOS, ADI-R, CARS, and SCQ were used less a
third of the time in ASD assessment. Thus, while evidence-based instruments are
available for the reliable, thorough assessment of students with ASD, school
psychologists either do not have access or lack sufficient training to make them
a part of their practice in the schools.
Because the knowledge base in ASD is changing so
rapidly, it is imperative that school psychologists remain current with the
research and up to date on scientifically supported approaches that have direct
application to the educational setting. School psychologists can help to ensure
that students with ASD receive an effective educational program by
participating in training programs designed to increase their understanding and
factual knowledge about best practice assessment and intervention /treatment
approaches.
Recommendations
Recommendations culled from the survey findings include the
following: (a) school psychologists need more in-depth, formal training
complete with supervision and consultation; (b) school psychology training
programs should focus more energy on teaching intervention strategies for
students with autism and include a separate course in ASD as part of the
curriculum; (c) increase the use of more psychometrically sound autism
instruments such as the ADOS and ADI-R in schools to provide better
identification and more complete intervention strategies; (d) consider resident ASD specialists within the school
and train
teams of school professionals to work as a unit with the autism-related cases to
ensure that the personnel are well-trained and have the experience necessary to
conduct reliable and valid assessments and treatment planning; (e) provide training for all school psychologists on best
practice guidelines for screening and assessment of ASD and identify measures with
and without empirical support; and (g) develop closer relationships with ASD
experts and service providers in the community. School districts may also want
to consider levels of training, levels of education, and years of experience
when assigning school psychologists who work with children who have ASD. Finally, the National Association of School Psychologists
(NASP) may consider developing guidelines and recommendations regarding the
minimal competencies needed in order to work with special populations such as
students with ASD.
