Which assessment focuses on identifying the function of a student’s challenging behavior to guide supports?

• A. Full and individual initial evaluation
• B. Functional behavior assessment
• C. Response to Intervention
• D. Psychoeducational assessment

Answer: (B)

Identifying why a student engages in challenging behavior is essential for choosing effective supports. A functional behavior assessment is specifically designed to determine the purpose or function behind a behavior by looking at what happens before the behavior (the trigger), what the behavior looks like, and what happens after (the consequence). By uncovering the function—whether the student is seeking attention, avoiding a task, obtaining a tangible item, or seeking sensory input—teachers can plan targeted interventions that address the root cause.

This approach guides supports like teaching an alternative, appropriate way to meet the same need, altering the environment to reduce triggers, and adjusting how adults respond so that the challenging behavior is not reinforced. For example, if a student acts out to gain attention, the plan would emphasize providing positive attention for appropriate behavior and minimizing attention to the disruptive behavior while teaching a substitute way to request help.

Other options don’t fit as well because they’re broader or focus on different purposes: a full and individual initial evaluation covers multiple domains for eligibility, not specifically the function of behavior; a Response to Intervention framework centers on tiered instruction and progress monitoring; a psychoeducational assessment examines cognitive, academic, and learning factors, not the function of behavior.
