What do educators need to know about EBPs for children with autism?
Page 2: Evidence-Based Practices
For Your Information
Two federal laws—the Every Student Succeeds Act (ESSA) and the Individuals with Disabilities Education Act (IDEA ’04)—mandate that educators use, to the greatest extent possible, evidence-based academic and behavioral practices and programs.
To improve the outcomes of children with ASD, educators should implement evidence-based practices (EBPs), strategies that have been shown to be effective in teaching appropriate behaviors and skills and decreasing inappropriate behaviors for a given population. There are evidence-based practices to improve academic and behavior outcomes for all students. However, this module will focus on strategies that have been shown to be effective in teaching appropriate behaviors and skills and decreasing inappropriate behaviors for students with ASD. The National Professional Development Center (NPDC) on Autism Spectrum Disorder has identified 27 evidence-based practices for improving outcomes for students with ASD.
|Antecedent-based intervention||Arrangement of events or circumstances that precede the occurrence of an interfering behavior and designed to lead to the reduction of the behavior.|
|Cognitive behavioral intervention||Instruction on management or control of cognitive processes that lead to changes in overt behavior.|
|Differential reinforcement of alternative, incompatible, or other behavior||Provision of positive/desirable consequences for behaviors or their absence that reduce the occurrence of an undesirable behavior. Reinforcement provided: a) when the learner is engaging in a specific desired behavior other than the inappropriate behavior (DRA), b) when the learner is engaging in a behavior that is physically impossible to do while exhibiting the inappropriate behavior (DRI), or c) when the learner is not engaging in the interfering behavior (DRO).|
|Discrete trial teaching||Instructional process usually involving one teacher/service provider and one student/client and designed to teach appropriate behavior or skills. Instruction usually involves massed trials. Each trial consists of the teacher’s instruction/presentation, the child’s response, a carefully planned consequence, and a pause prior to presenting the next instruction.|
|Exercise||Increase in physical exertion as a means of reducing problem behaviors or increasing appropriate behavior.|
|Extinction||Withdrawal or removal of reinforcers of interfering behavior in order to reduce the occurrence of that behavior. Although sometimes used as a single intervention practice, extinction often occurs in combination with functional behavior assessment, functional communication training, and differential reinforcement.|
|Functional behavior assessment (FBA)||Systematic collection of information about an interfering behavior designed to identify functional contingencies that support the behavior. FBA consists of describing the interfering or problem behavior, identifying antecedent or consequent events that control the behavior, developing a hypothesis of the function of the behavior, and/or testing the hypothesis.|
|Functional communication training||Replacement of interfering behavior that has a communication function with more appropriate communication that accomplishes the same function. Functional communication training usually includes FBA, differential reinforcement of alternative behavior, and/ or extinction.|
|Modeling||Demonstration of a desired target behavior that results in imitation of the behavior by the learner and that leads to the acquisition of the imitated behavior. This EBP is often combined with other strategies such as prompting and reinforcement.|
|Naturalistic intervention||Intervention strategies that occur within the typical setting/activities/routines in which the learner participates. Teachers/service providers establish the learner’s interest in a learning event through arrangement of the setting/activity/routine, provide necessary support for the learner to engage in the targeted behavior, elaborate on the behavior when it occurs, and/or arrange natural consequences for the targeted behavior or skills.|
|Parent-implemented intervention||Parents provide individualized intervention to their child to improve/increase a wide variety of skills and/or to reduce interfering behaviors. Parents learn to deliver interventions in their home and/or community through a structured parent training program.|
|Peer-mediated instruction and intervention||Typically developing peers interact with and/or help children and youth with ASD to acquire new behavior, communication, and social skills by increasing social and learning opportunities within natural environments. Teachers/service providers systematically teach peers strategies for engaging children and youth with ASD in positive and extended social interactions in both teacher-directed and learner-initiated activities.|
|Picture Exchange Communication System (PECS)||Learners are initially taught to give a picture of a desired item to a communicative partner in exchange for the desired item. PECS consists of six phases which are: (1) “how” to communicate, (2) distance and persistence, (3) picture discrimination, (4) sentence structure, (5) responsive requesting, and (6) commenting.|
|Pivotal response training||Pivotal learning variables (i .e., motivation, responding to multiple cues, self-management, and self-initiations) guide intervention practices that are implemented in settings that build on learner interests and initiative.|
|Prompting||Verbal, gestural, or physical assistance given to learners to assist them in acquiring or engaging in a targeted behavior or skill. Prompts are generally given by an adult or peer before or as a learner attempts to use a skill.|
|Reinforcement||An event, activity, or other circumstance occurring after a learner engages in a desired behavior that leads to the increased occurrence of the behavior in the future.|
|Response interruption/ redirection||Introduction of a prompt, comment, or other distracters when an interfering behavior is occurring that is designed to divert the learner’s attention away from the interfering behavior and results in its reduction.|
|Scripting||A verbal and/or written description about a specific skill or situation that serves as a model for the learner. Scripts are usually practiced repeatedly before the skill is used in the actual situation|
|Self-management||Instruction focusing on learners discriminating between appropriate and inappropriate behaviors, accurately monitoring and recording their own behaviors, and rewarding themselves for behaving appropriately.|
|Social narratives||Narratives that describe social situations in some detail by highlighting relevant cues and offering examples of appropriate responding. Social narratives are individualized according to learner needs and typically are quite short, perhaps including pictures or other visual aids.|
|Social skills training||Group or individual instruction designed to teach learners with autism spectrum disorders (ASD) ways to appropriately interact with peers, adults, and other individuals. Most social skill meetings include instruction on basic concepts, role-playing or practice, and feedback to help learners with ASD acquire and practice communication, play, or social skills to promote positive interactions with peers.|
|Structured play group||Small group activities characterized by their occurrences in a defined area and with a defined activity, the specific selection of typically developing peers to be in the group, a clear delineation of theme and roles by adult leading, prompting, or scaffolding as needed to support students’ performance related to the goals of the activity.|
|Task analysis||A process in which an activity or behavior is divided into small, manageable steps in order to assess and teach the skill. Other practices, such as reinforcement, video modeling, or time delay, are often used to facilitate acquisition of the smaller steps.|
|Technology-aided instruction and intervention (TAII)||Instruction or interventions in which technology (e.g., tablet, computer, computer program, online activity) is used to increase or maintain functional skills and behaviors.|
|Time delay||In a setting or activity in which a learner should engage in a behavior or skill, a brief delay occurs between the opportunity to use the skill and any additional instructions or prompts. The purpose of the time delay is to allow the learner to respond without having to receive a prompt and thus focuses on fading the use of prompts during instructional activities .|
|Video modeling||A visual model of the targeted behavior or skill (typically in the behavior, communication, play, or social domains), provided via video recording and display equipment to assist learning in or engaging in a desired behavior or skill .|
|Visual support||Any visual display that supports the learner engaging in a desired behavior or skills independent of prompts. Examples of visual supports include pictures, written words, objects within the environment, arrangement of the environment or visual boundaries, schedules, maps, labels, organization systems, and timelines.|

With so many EBPs from which to choose, how can educators or practitioners determine which of them to use with a specific child? The four steps outlined below can help educators and practitioners make a more informed decision when they select an EBP.
The target behavior is the behavior the teacher wants to change. This should be a discrete behavior that is directly observable, measurable, and clearly defined. The definition of the behavior should:
- Describe the behavior in an observable manner
- Describe the behavior in measurable terms (i.e., instances of the behavior can be counted or timed)
- Identify the setting in which the behavior occurs
Note the difference in the definitions below.
- Ambiguous and subjective definition: Michelle violates other’s personal space.
- Clear and observable definition: When talking to someone, Michelle stands within a foot of that person.
Defining behavior in this manner allows multiple professionals to observe and collect objective data on the behavior. If multiple professionals gather data using the second definition of Michelle’s behavior, they are more likely to collect data on the same behavior rather than on their subjective opinion of personal space violation.
To learn more about how to clearly define a student’s behavior so that when it occurs it can be reliably identified, measured, or counted, visit the following IRIS Case Study:
Baseline data refers to the level (i.e., frequency, duration) at which a behavior occurs before a strategy or intervention is implemented. These data should be gathered for at least four days or until a pattern of behavior is evident. By comparing these data to data collected after the strategy has been implemented, educators can determine whether it is effective for the student.
To learn more about collecting observational data on a child or student’s behavior, visit the following IRIS Case Study:
Once the target behavior has been identified and baseline data collected, the goal needs to be indicated in a child’s individualized education program (IEP) or individualized family service plan (IFSP). The goal should include information about:
- When or where the behavior will be performed
- What behavior should be displayed
- Specific, measurable criterion for mastery
Note the difference in the goals below.
- Poorly written goal: Michelle will respect other’s personal space.
- Observable goal: When talking to friends or school personnel, Michelle will stand a minimum of 1½ feet from them at least 90% of the time.
The next step in this process is to determine which EBPs can address the target behavior. With those in mind, educators can select an EBP that is likely to be effective for a student. The IFSP or IEP team should consider the following when they choose an EBP:
- The characteristics of the child and her or his family (e.g., the child’s strengths and challenges, what strategies have or have not worked in the past)
- The student’s goal (i.e., what the student is expected to achieve and in what learning domain)
- The expertise and experience of the teacher in successfully implementing specific EBPs
- The availability of resources (e.g., equipment, personnel) necessary to implement a given EBP
When they select a practice to implement with a child or student, educators and practitioners should understand that:
- When selecting a target behavior and EBP, it is important to collaborate with parents. A behavior that is problematic at school is also often problematic at home. When parents and teachers implement the same EBP, the probability that the strategy will be effective across multiple settings increases.
- Just because a practice is deemed evidence-based does not guarantee that it will be effective for every student.
- Information about treating and even curing autism is abundantly available on the Internet, but many of these practices are unproven, and are sometimes even harmful. For this reason, educators and practitioners should rely on trustworthy sources to identify evidence-based practices.

- 27 evidence-based practices for students with ASD
Once an EBP has been selected and implemented with a child, the educator or practitioner needs to collect data on the behavior to evaluate how the EBP is working for the individual student. It is also important to determine whether the EBP was implemented with fidelity (i.e., implemented as the developer intended), especially if the EBP was not effective for the student. Kara Hume and Ilene Schwartz discuss selecting an EBP, implementing a practice with fidelity, and evaluating whether an EBP is effective for a student.

Are the EBPs for students with autism also high-leverage practices?
High-leverage practices (HLPs) are practices often used by teachers that have been shown to increase student performance. HLPs that can be used with students with ASD include small-group instruction, functional behavior assessments, peer-assisted strategies, and organized and supportive learning environments. Listen as Kara Hume discusses some of these HLPs and the overlap with EBPs for students with autism (time: 0:59).
