Learners with Autism Spectrum Disorder (ASD) often struggle with learning new skills or behaviors, especially when these behaviors are complex or have multiple components. Task analysis (TA) can be used to help break down and teach these chained behaviors. Chained behaviors are behaviors or skills which consist of multiple steps such as tying shoes, grocery shopping, writing a paper, or cooking. Once chained behaviors are broken into smaller steps, team members work with the learner to systematically teach the individual steps. As the learner masters the individual steps, the learner will gradually become more independent using the target skill or behavior. This evidence-based practice (EBP) overview on TA includes the following packet components: (1) Overview; (2) Evidence-base; (3) Step-by-Step Guide; (4) Implementation Checklist; (5) Data Collection Sheets; (6) Tip Sheet for Professionals; (7) Parent Guide; (8) Additional Resources; (9) CEC Standards; and (10) Module References.
