This document discusses functional behavior assessments (FBAs) which are used to understand the purpose or function of problematic behaviors in educational settings. It defines key terminology related to behavior, like topography which refers to the physical form of a behavior, and function which refers to why the behavior occurs. The document also summarizes different types of problematic behaviors, variables that maintain behaviors, and the three main types of FBAs - direct observation, indirect interviews, and experimental analysis. It provides examples of questions that can be asked during indirect assessments to determine if a behavior is maintained by escape, attention, access to tangibles, or automatic reinforcement. The overall purpose of FBAs is to identify the function to develop effective behavior support plans.
