Which assessment measures functional performance and behavior?

• A. Standardized Assessment
• B. Functional Behavioral Assessment (FBA)
• C. Individualized Education Plan (IEP)
• D. Diagnostic Assessment

Answer: (B)

The assessment that specifically measures functional performance and behavior is the Functional Behavioral Assessment (FBA). An FBA is designed to identify the reasons behind specific behaviors exhibited by students, particularly those who may have behavioral challenges. It focuses on gathering data about the behavior of interest in various contexts, understanding the conditions that lead to the behavior, and determining the consequences that maintain the behavior.

By collecting this information, educators and specialists can develop a clearer picture of the student's needs, which is critical for creating effective intervention strategies. This process ultimately aims to support the student by addressing the underlying causes of their behavior, rather than just responding to the behaviors themselves.

In contrast, other assessment types serve different purposes. Standardized assessments typically measure academic skills and knowledge in a controlled manner, while an Individualized Education Plan (IEP) is a document that outlines specific educational goals and services for a student with disabilities based on assessment data. Diagnostic assessments are used to identify specific learning difficulties but do not focus primarily on functional behavior. Thus, the FBA uniquely suits the need to measure functional performance and behavior.
