This manual takes school practitioners step by step through conducting functional behavioral assessments and using them to plan effective interventions. The authors present a cogent rationale for the use of functional behavioral assessment (FBA), clearly explaining its advantages over traditional approaches to dealing with problem behavior. Basic terms and procedures are defined and the process of working with individual students is described in depth. Bringing concepts to life with case examples, the authors also include a variety of sample FBA reports and corresponding positive behavior support plans. A Q&A chapter offers straightforward answers to practitioners' frequently asked questions. The volume provides all of the tools needed to complete a reliable and valid FBA, including forms, questionnaires, and worksheets, conveniently designed in a ready-to-photocopy format.
