Fleury1, Julie L. Thompson2, and Connie Wong3 Abstract Due to difficulties associated with autism spectrum disorder (ASD), many children with ASD will require additional support to actively participate in classroom activities. Therefore, it is important that professionals who work with young children with ASD know what skills to teach and how to teach them. Using the recent evidence-based practice review conducted by the National Professional Development Center on ASD, we have identified studies that targeted school readiness behaviors which can have implications for academic skill development. In this article, we evaluate (a) the types of skills that have been taught to preschool children with ASD, (b) the strategies used to teach specific skills, and (c) other descriptive information, such as who delivered the intervention and the setting in which the intervention 1University of Minnesota, Minneapolis, USA 2University of North Carolina at Charlotte, USA 3University of North Carolina at Chapel Hill, USA Corresponding Author: Veronica P.

We conclude by offering suggestions for future research and considerations for professional development. Keywords autism spectrum disorder, school readiness, evidence-based practice, preschool Inclusion of children with autism spectrum disorder (ASD) in general education settings has proven to be a significant challenge despite legal mandates (Individuals With Disabilities Education Act, 2004; Kieron, 2013; Koegel, Matos-Freden, Lang, & Koegel, 2012). Only 58% of children with ASD spend more than 40% of their day in general education settings compared with 82% of children from all other disability categories (U.S. Department of Education, Office of Special Education and Rehabilitative Services, Office of Special Education Programs, 2013). This statistic implies that a disproportionate number of children with ASD are educated in more restrictive environments, perhaps due to the complex needs of children with ASD that result from deficits in social communication and social interaction, and restrictive, repetitive patterns of behavior (American Psychiatric Association, 2013). In school settings, children with ASD demonstrate significantly higher behavioral excesses such as aggression or self-injurious behavior and deficits including limited communication and difficulty participating in school routines (Ashburner, Ziviani, & Rodger, 2010). These behaviors may lead to placement in more restrictive settings (Machalicek, O’Reilly, Beretvas, Sigafoos, & Lancioni, 2007; Scruggs & Mastropieri, 1996). The trajectory of special education has moved beyond mere access to free appropriate public education to a greater emphasis on educational achievement for all individuals with disabilities (Kieron, 2013; Koegel et al., 2012). It is important for children with ASD to have full access to the general curriculum content for their assigned grade level regardless of whether they are served primarily in self-contained or inclusive settings. Accordingly, we need to have a better understanding about the foundational skills that will enable children with ASD to appropriately participate in classroom activities, thereby improving their opportunities to access the general education curriculum. School Readiness for Children With ASD The National Governors Association (NGA; 2005) Task Force on School Readiness described children’s school readiness as manifested in five areas: Downloaded from bmo.sagepub.com at MICHIGAN STATE UNIV LIBRARIES on May 13, 2015 71 Fleury et al. health and motor skill development (e.g., vision, hearing, gross and fine motor skills), socio-emotional development (e.g., self-regulation, establishing reciprocal relationships with peers and adults), motivation to learn (e.g., persistence, sustained attention to educational tasks), language and early literacy skills (e.g., listening and story comprehension, phonemic awareness, print concepts), and conceptual knowledge and application (e.g., vocabulary, reasoning, associations, problem solving). All of these domains are important to building a foundation for learning. Characteristics of ASD (e.g., social communication deficits, restricted interests) may place children with ASD at a distinct disadvantage for naturally developing some facets of school readiness skills. The Pre-Elementary Longitudinal Study (PEELS) is a national study that addressed four key areas of school readiness—emergent literacy, early math proficiency, motor performance, and social behavior—in preschool children with special needs (National Center for Special Education Research, 2006). Data for children with ASD show an uneven profile in school readiness behavior. As a group, children with ASD performed above the population mean on their ability to identify letters and words and were within normal limits in receptive vocabulary, quantitative concepts, and motor skills measures. As expected, the greatest skill deficit for children with ASD was in the domain of social behavior. Children with ASD performed two standard deviations below the population mean on the social skills subscale of the Preschool and Kindergarten Behavior Scales (PKBS-2). This subscale is used to assess personal behaviors such as “works or plays independently,” “follows rules,” “accepts decisions made by adults,” and interpersonal skills such as cooperation, turn-taking, and comforting other children. Furthermore, children with ASD scored significantly higher than the norm on the PKBS-2 problem behavior subscale. Higher scores on this scale indicate greater concern about problem behavior and include items such as “defies teacher or caregiver,” “takes things away from other children,” “is restless or fidgety.” Children with ASD also had difficulty on measures of independence, self-control, and personal responsibility (Adaptive Behavior Assessment Scale, ABAS-II) which includes items such as “follows adults request to quiet down and behave,” and “works independently and asks for help only when necessary.” In fact, children with ASD had the poorest performance on the PKBS-2 problem behavior subscale and the ABAS-II self-direction scale compared with all other disability groups. These early deficits in school readiness, primarily in the social behavior domain, can have implications for future academic success for children with ASD. Lloyd, Irwin, and Hertzman (2009) conducted a longitudinal study that compared kindergarten school readiness scores with fourth-grade assessment outcomes for individuals with disabilities, including 175 children with ASD. Downloaded from bmo.sagepub.com at MICHIGAN STATE UNIV LIBRARIES on May 13, 2015 72 Behavior Modification 39(1) These researchers found that 88% of the children with ASD did not demonstrate school readiness when assessed in kindergarten and approximately 86% of children with ASD “did not meet expectations” in mathematics and literacy following fourth-grade assessments. These results provide evidence of a correlation between school readiness behavior and later school outcomes for children with ASD. If we expect children with ASD to be able to access and benefit from the general education curriculum, professionals who work with young children with ASD will need to identify what skills to teach and how to teach them. A number of reports have been published that provide a broad overview of focused instructional practices (National Autism Center, 2009; Wong et al., 2014) and comprehensive treatment models (Dawson et al., 2010; Rogers & Vismara, 2008; Strain & Bovey, 2011) that are supported by research to improve developmental outcomes for children with ASD. The National Professional Development Center (NPDC) on ASD recently published an updated report of evidence-based practices for children, youth, and adults with ASD. The NPDC report represents the work of a large systematic review of focused intervention strategies for individuals with ASD that were published in peer-reviewed journals between 1990 and 2011. Content analysis of these studies yielded 27 evidence-based practices that encompass a variety of outcomes, including those that have been found to be effective in improving pre-academic/academic skills and school readiness skills for individuals as young as toddlers. In this report, the authors differentiated between studies that improved pre-academic and academic skills from those that address school readiness skills. The NPDC work group defined pre-academic/academic skills as outcomes broadly related to performance on tasks typically taught and used in school settings, whereas school readiness was defined as outcomes that are related to task performance but are not directly related to task content. Accordingly, studies that targeted skills such as matching, sorting, reading, and letter identification were classified as pre-academic/academic skills whereas engaging in tasks, orienting to materials, remaining in seat or activity area, and responding to instruction were considered school readiness skills. In addition to knowing what skills to teach and how to teach them, it is also important to identify where these studies are conducted and who delivered the intervention to facilitate the translation of research to practice. Historically, most studies have been implemented in clinical settings and/or with highly trained behavior analysts (Kasari & Smith, 2013). Although this may be helpful in identifying potentially effective strategies, it does not guarantee that classroom teachers and families will readily accept or be able to implement these strategies in their classrooms or homes. To ensure strategies Downloaded from bmo.sagepub.com at MICHIGAN STATE UNIV LIBRARIES on May 13, 2015 73 Fleury et al. can become sustained practices which are practically implemented, it is important to identify feasible and generalizable instructional strategies that can be readily implemented in the public school setting where the majority of children with ASD are educated (Kasari & Smith, 2013). As a result, it is important to identify the interventionist and setting of implementation to guide judgments regarding optimal strategies to support school readiness. Focus of the Present Review To date, a systematic literature review has not been conducted to gain broader insights into preparing young children with ASD to be school ready and equip professionals to effectively teach school readiness skills. The purpose of this study is to review the school readiness literature to evaluate (a) the types of skills that have been taught to preschool children with ASD, (b) the strategies used to teach specific skills, and (c) other descriptive information, such as who delivered the intervention and the setting in which the intervention took place. We anticipate that this information will both highlight areas in need of further study for researchers and also serve as a valuable resource to practitioners who wish to include evidence-based practices as the basis of educational programming. Method Selection Criteria We identified articles to include in our review through the NPDC report, “Evidence-Based Practices for Children, Youth, and Young Adults With Autism Spectrum Disorder” (Wong et al., 2014). The NPDC report lists article citations according to the specific evidence-based practices (EBP) they support. Although there is general information about the overall number of studies that were published for each target outcome, specific articles were not organized by outcome categories. For this study, we used the NPDC database of articles to identify 67 studies that targeted school readiness as an outcome measure. We classified preschoolers by their age at the time of study. After screening the participants section of each article, we found 26 studies that included at least 1 child with ASD who was preschool age (between the ages of 3 years 0 months and 5 years 11 months). We excluded one study in this review because the intervention solely targeted the reduction of challenging behaviors, and did not address corresponding improvement on any school readiness behavior. In this article, we focus our review on the 25 intervention studies (21 single-case design; 4 group design) that documented improvement in school readiness skills for preschoolers. Downloaded from bmo.sagepub.com at MICHIGAN STATE UNIV LIBRARIES on May 13, 2015 74 Behavior Modification 39(1) Coding Procedures The reviewers who contributed to the NPDC report participated in a rigorous training to evaluate studies for methodological rigor using criteria that were developed specifically for the project. NPDC reviewers also coded descriptive features for each study that they determined to be methodologically acceptable. Specifically, reviewers coded information about study participants (diagnosis, co-occurring conditions, age), intervention strategies used by researchers (see the appendix), and dependent variables (name, description) measured in each study. Finally, reviewers selected outcome categories that best described child outcomes in each study from 12 outcome categories including social, communication, challenging/interfering behaviors, joint attention, play, cognitive, school readiness skills, pre-academic/academic, motor, adaptive/self-help, vocational, and mental health (refer to Wong et al., 2014 for more detail about reviewer training, article inclusion criteria, and coding procedures). We limited our review to those studies that were classified as having a school readiness outcome. Information about intervention strategies (evidence-based practices) and dependent variables were taken directly from the NPDC data set. We did not need to further evaluate the studies for sample, appropriateness of design, or quality of data analysis because all studies included in the NPDC report were already evaluated for methodological rigor. Rather, we evaluated each article on additional variables that were not included in the NPDC review, specifically information pertaining to the setting where intervention procedures took place and who delivered intervention procedures. Setting. The environment in which the study procedures took place was analyzed in terms of the following set of definitions: Classroom. A school setting in which the child is taught alongside their peers. This term encompasses a number of different educational settings, including: general education, special education, inclusive/integrated classrooms, and self-contained classrooms. Special education classrooms that also functioned as 1:1 settings were coded here provided that other peers (with or without disabilities) were present in the environment. Study procedures that take place on the playground during recess were classified here provided that peers were present at the time of the intervention. Specialized setting (1:1 room). An environment in which the child receives instruction in a 1:1 context separate from the classroom, such as therapy rooms, school office, testing rooms, and specialist rooms. These settings have limited environmental distractions, typically without peers present. We also classified any study that took place within a Downloaded from bmo.sagepub.com at MICHIGAN STATE UNIV LIBRARIES on May 13, 2015 75 Fleury et al. clinical setting here. Home. The setting where the child permanently resides. Study procedures may take place in any room within the child’s residence, such as the living room, kitchen, or therapy room within the home. Interventionist. The person who was primarily responsible for carrying out the intervention procedures was evaluated using the following definitions: Researcher. A member of the research team primarily carries out the intervention procedure. This includes principal investigators, co-principal investigators, research assistants, graduate students, and others who were employed by the research team. School Personnel. An individual with some professional training carries out the intervention procedures as part of their job. The individual was not directly employed by the research group, but may have received stipends for their participation in the research project. This includes special education teachers, general education teachers, paraprofessionals, and other specialists such as speech-language pathologists, occupation therapists, and/or physical therapists. Researchers who claim that “therapists” or “interventionists” conducted the study were also classified in this category. Parent. A child’s caregiver carries out the intervention procedure. Student/ Peers. The child or his or her classmate(s) or peer(s) are taught to carry out the intervention procedures. Setting and intervention variables are not mutually exclusive. We coded all variables that applied for each intervention study. Although many studies were conducted only in one setting by one interventionist type (e.g., a member of the research team who conducted the procedures in a 1:1 therapy room), some studies were carried out across different settings and/or with different interventionists (i.e., Buggey, Hoomes, Sherberger, & Williams, 2011; Kern, Wolery, & Aldridge, 2007; Shogren, Lang, Machalicek, Rispoli, & O’Reilly, 2011). Reliability Information about article inclusion, intervention strategies, and child outcomes were taken directly from the NPDC database and were therefore not included in reliability calculations. Interrater reliability was calculated on 100% of coding variables unique to this review (i.e., setting and interventionist) for 100% of included studies. We calculated reliability using a point-bypoint formula: (agreement/[agreement + disagreement]) × 100. Interrater reliability reached acceptable levels (Horner et al., 2005) for both setting (M = 86%) and interventionist (M = 82%) categories. The first author and the coder reviewed all discrepancies and arrived at a consensus code to be used in final analyses.

The NPDC reviewers identified the primary intervention strategy used in each study that was included in the evidence-based practice report. We pulled this information directly from the NPDC database for this review. Our analysis revealed that 18 of the 27 identified evidence-based practices were used by researchers to improve school readiness behaviors in preschoolers. Evidence-based practices used to improve school readiness included antecedent-based intervention, differential reinforcement, exercise, discrete trial teaching, functional behavior assessment, functional communication training, modeling, parent-implemented intervention, prompting, reinforcement, response interruption and redirection, scripting, self-management, technology-aided instruction and intervention, time delay, video modeling, and visual supports. There were three additional intervention practices that were used that did not meet the NPDC criteria for an evidence-based practice: behavioral momentum intervention, touch therapy, and music therapy. Descriptions of instructional strategies used to promote school readiness behavior are provided in the appendix. Child Outcomes School readiness is a broad term that encompasses a number of behaviors. Our analyses revealed that specific child outcome variables differed across studies, but could be organized into three general categories: classroom behavior, social-communication, and challenging behavior. Several studies addressed multiple behaviors that fit into several categories. Thirty-two percent of studies (n = 8) measured changes in classroom behavior. These behaviors relate to children’s ability to appropriately participate in independent tasks within the classroom environment. Examples of classroom behavior include: attending to activities, engagement, correct responding, complying with teacher directions or classroom routines. Second, we categorized a number of child outcomes as improvements in social-communication or social interaction skills (n = 7; 28%). Behaviors in this category support the child’s ability to interact with his or her peers or adults. Examples include reciprocal conversations in play, initiating social interactions, responding to peers’ social invitations, appropriately expressing needs or desires, and inquiries about the environment or classroom schedule.

Child demographics reflect information that was reported by the authors of the original study. Researchers who reported autism severity used the Childhood Autism Rating Scale (CARS; Schopler, Reichler, & Renner, 1988). Information regarding instructional strategy and child outcome measures was taken from the NPDC evidencebased practice report (Wong et al., 2014). DTT = Discrete trial teaching; PDD-NOS = pervasive developmental disorder–not otherwise specified. aThese strategies did not meet the NPDC criteria for an evidence-based practice due to insufficient evidence.

However, many studies (n = 10) simultaneously decreased occurrences of challenging behavior. We defined challenging behavior as problematic behavior that may prevent the child’s and his or her or peers’ ability to learn including, but not limited to: stereotypic behavior; elopement; pushing materials away; inappropriate vocalizations; aggressive behaviors such as hitting, biting, and pinching. Improvements in classroom behavior and decreased challenging behavior were reported in six studies (24%). A total of four studies (16%) addressed both social communication or social interaction skills and challenging behavior. Figure 1 illustrates the instructional strategies that addressed specific child outcomes. Setting Based on our definitions of environmental setting, the majority of studies were based solely out of the classroom (n = 9; 36%) or in a specialized setting (n = 9; 36%). The remaining studies were conducted in the child’s home (n = 2; 8%) or in a combination of the settings (n = 5; 20%). Interventionist In the majority of the studies, the researcher (n = 11; 44%) or school personnel (n = 8; 32%) were solely responsible in delivering the intervention procedures. Parents were trained to serve as the interventionist in 16% of the studies, either as the sole interventionist (n = 2; 8%) or in combination with school personnel (n = 2; 8%). The student or peers were trained to carry out intervention procedures in 8% of the studies alongside school personnel and/ or researchers (n = 2). The exact combination of setting and interventionist classification by study is displayed in Table 2. Discussion There has been much debate regarding appropriate educational placements for children with ASD. Some studies report that children with ASD who are served in inclusive settings spend more time participating in curricular activities and demonstrate significant gains in academic achievement compared with those in self-contained settings (Kurth & Mastergeorge, 2012). Others argue that inclusive settings are less appropriate, and therefore less beneficial, for children with ASD than alternative settings in which school personnel are able to provide intensive interventions that are necessary to support the complex needs of children with ASD (Ashburner et al., 2010; Osborne & Downloaded from bmo.sagepub.com at MICHIGAN STATE UNIV LIBRARIES on May 13, 2015 84 Downloaded from bmo.sagepub.com at MICHIGAN STATE UNIV LIBRARIES on May 13, 2015 st ue sp te on re eq n/ ria ati ar l atio op aliz a r ke ci iti a pp oc o A v S in M se on u c pi ty ior eo v er eha t S b t o te en lt a sa cip em fu arti op e l R p E i D ty ili tib ac str Challenging Behavior Note.

Regardless of the educational setting, the relationship between social skills and academic performance has been well established by research. Children who enter formal schooling lacking social and emotional competence will likely have difficulty succeeding in school (McClelland, Morrison, & Holmes, 2000; National Center for Special Education Research, 2006). Deficits in social-communication and social interactions are a benchmark characteristic of ASD (American Psychiatric Association, 2013). These difficulties, combined with restricted, repetitive behaviors can make it especially challenging for children with ASD to fully participate in classroom activities. These behaviors may limit their access to the general education curriculum and typically developing peers, thereby reducing opportunities that children with ASD have to develop both the academic and social skills that relate to positive school outcomes. Because of characteristics associated with ASD, children with ASD may present with several behaviors that teachers will need to address if children are to benefit from classroom instruction. The results presented in this review provide practitioners and researchers with an overview of different instructional practices that have been used to prepare preschool children with ASD to engage in classroom routines and activities. Implications for Classroom Practice Children who are unresponsive to a teacher’s direction, unable to independently complete tasks, or engage in stereotypic behaviors usually cannot fully participate in, and thereby benefit from, classroom activities. Many of these behaviors, however, are amenable to early intervention. In fact, several of these behaviors were the target of interventions summarized in this review. Analyses reveal 18 evidence-based practices that directly or indirectly improved independent classroom behavior (i.e., compliance, following classroom routine, engagement in tasks), social communication and social interaction skills (i.e., making requests, social initiations, social responses), and/or reduced challenging behavior (i.e., stereotypy, refusal to participate, elopement). It should be noted that three practices that addressed school readiness—behavior momentum interventions, music, and touch therapy—did not meet the NPDC criteria to be called an evidence-based practice. Practitioners should be cautious about using these strategies until more research is published that demonstrates clear positive effects for children with ASD. In many cases, different strategies were used to address a target skill. For example, a number of studies in this review demonstrated improvements in children’s ability to attend to tasks. However, researchers took different intervention approaches to improve children’s task engagement including Downloaded from bmo.sagepub.com at MICHIGAN STATE UNIV LIBRARIES on May 13, 2015 87 Fleury et al. antecedent-based interventions (Rispoli et al., 2011), exercise (Oriel, George, Peckus, & Semon, 2011), functional behavior assessment (Kodak, Fisher, Clements, Paden, & Dickes, 2011), reinforcement (Reichle, Johnson, Monn, & Harris, 2010; Tarbox, Ghezzi, & Wilson, 2006), self-management (Shogren et al., 2011), and technology-aided instruction (Moore & Calvert, 2000). All of the intervention strategies that are included in this review are considered focused intervention practices—strategies that are designed to address a single skill or goal (Odom, Collet-Klingenberg, Rogers, & Hatton, 2010). A major advantage of focused intervention practices is that practitioners can select and combine different evidence-based practices that best suit the child’s individual needs and the learning environment. Almost half of the studies included in the present review were conducted in classrooms, and the number of studies in which school personnel delivered intervention procedures equaled those in which a researcher implemented the intervention. The applied nature of this research holds promise for having direct benefits for children with ASD who are being educated in classrooms, homes, and in specialized 1:1 settings. To improve school outcomes for children with ASD, educators must have access to empirically validated strategies such as those reported in this review. We merely provide a broad overview of strategies related to specific child outcomes in this review. If educators are expected to include these strategies as part of a child’s educational programming, this information will need to be supplemented by additional training. Pre-service and in-service educators may find publicly available training resources particularly useful such as those provided by the NPDC on ASD (http://autismpdc.fpg.unc.edu/) and the Autism Internet Modules available through the Ohio Center for Autism and Low Incidence (OCALI; www.ocali.org). Implications for Research This review complements a growing body of research dedicated to helping educators provide effective classroom instruction. While previous researchers have focused on one particular learning environment such as inclusive classrooms (Crosland & Dunlap, 2012; Harrower & Dunlap, 2001), this review examined strategies that have been successfully used in different environments where learning can occur including classrooms, specialized settings, and homes. We found only a few studies (Kaiser, Hancock, & Nietfeld, 2000; Schindler & Horner, 2005) that were conducted in homes in which a caregiver served as the primary interventionist. Given that homebased experiences contribute to children’s accomplishments (Dunst, Trivette, Masiello, Roper, & Robyak, 2006) and that many young children may not be attending preschool full-time, there is a need to examine how to best support Downloaded from bmo.sagepub.com at MICHIGAN STATE UNIV LIBRARIES on May 13, 2015 88 Behavior Modification 39(1) families so they are able to implement specific strategies in their homes. In a similar vein, social validity—determining whether the focus of the intervention and behavioral changes align with the expectations of the child’s community—is an integral component of applied intervention work (Kazdin, 1982; Schwartz & Baer, 1991). The inclusion of social validity measures was not a variable of focus in this review; however, this valuable information will allow researchers to determine whether educators and families view strategies as being acceptable and the child outcomes as being relevant to their unique situations. Limitations The corpus of studies reviewed here was obtained from the NPDC database and was flagged by the NPDC reviewers as targeting school readiness. Because school readiness is a broad term that encompasses several developmental domains, we may have excluded a number of relevant studies if they were categorized under a different outcome category, such as pre-academic/ academic skills, social skills, and communication skills. This review solely focuses on a subset of skills children with ASD need to improve the likelihood that they are successful in school. It is important for us to stress that school readiness involves much more than children’s readiness. If we expect to improve academic outcomes for children with ASD, we will need to improve our knowledge about child-focused intervention strategies as well as ways to prepare families, communities, early childhood programs, and schools to create supportive environments that meet the unique needs of children with ASD (Carta, 2009; NGA, 2005). Several resources have been published about the characteristics of high-quality educational environments that incorporate developmentally appropriate practices for young children (e.g., Bredekamp & Copple, 1997; Davis, Kilgo, & Gamel-McCormick, 1998; Sandall, McLean, & Smith, 2000). Although a further description of such environments are beyond the scope of this article, we feel that it is important to emphasize that quality programs are essential for all young children, especially those with disabilities. Such environments provide a solid foundation on which practitioners can embed appropriate learning opportunities for young children with ASD (Sandall & Schwartz, 2002). For many children with ASD, however, educators will also need to provide individual support to children using specific child-focused intervention strategies. It is our intention that this review will guide educators in selecting empirically validated strategies to address specific behaviors that act as barriers to effective classroom instruction for many children with ASD.

Appendix Definitions of Instructional Practices Used to Address School Readiness Behavior Evidence-based practice Definition Antecedent-based intervention (ABI) Arrangement of events or circumstances that precede the occurrence of an interfering behavior and designed to lead to the reduction of the behavior. Differential reinforcement of Provision of positive/desirable consequences alternative, incompatible, for behaviors or their absence that reduce or other behavior (DRA/ the occurrence of an undesirable behavior. I/O) 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 (DTT) 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 (ECE) Increase in physical exertion as a means of reducing problem behaviors or increasing appropriate behavior. Functional behavior Systematic collection of information about an assessment (FBA) 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 Replacement of interfering behavior that has a training (FCT) communication function with more appropriate communication that accomplishes the same function. FCT usually includes FBA, DRA, and/or extinction.

Modeling is often combined with other strategies such as prompting and reinforcement. 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. Typically developing peers interact with and/or help children and youth with autism spectrum disorder (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 learnerinitiated activities. 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. 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. 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. 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. Instruction focusing on learners discriminating between appropriate and inappropriate behaviors, accurately monitoring and recording their own behaviors, and rewarding themselves for behaving appropriately.

Appendix (continued) Evidence-based practice Technology-aided instruction and intervention (TAII) Time delay (TD) Video modeling (VM) Visual supports (VS) Other Practices Behavior momentum Music therapy Touch therapy Definition Instruction or interventions in which technology is the central feature supporting the acquisition of a goal for the learner. Technology is defined as “any electronic item/equipment/application/or virtual network that is used intentionally to increase/ maintain, and/or improve daily living, work/ productivity, and recreation/leisure capabilities of adolescents with autism spectrum disorders” (Odom, Thompson, et al., 2013). 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. 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. 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. Definition Organization of behavior expectations in a sequence in which low probability/preference behaviors are embedded in a series of high probability/preference behaviors to increase the occurrence of the low probability/preference behaviors Songs and music used as a medium through which student’s goals may be addressed Systematic touch or massage Source.
