Aiden is a student identified with autism spectrum disorder who is exhibiting aggressive behaviors in his special education classroom. The Individualized Education Program (IEP) team is currently taking baseline data to complete a functional behavioral assessment. A primary purpose of collecting baseline data when completing a functional behavioral assessment is to

While designing a behavioral intervention plan is a subsequent step that follows the assessment, it is not the primary purpose of collecting baseline data. The plan is developed after identifying behavior patterns and understanding the underlying functions of the behaviors, rather than being the initial goal of baseline data collection.

Determining the effectiveness of a behavior plan occurs after it has been implemented and is assessed over time. Baseline data is collected before any interventions are applied, making it impossible to evaluate effectiveness at that stage. Therefore, this choice misrepresents the timing and purpose of baseline data collection.

Teaching replacement behaviors is an important part of behavioral interventions, but it is not the primary goal of collecting baseline data. Baseline data serves to analyze current behaviors before any teaching or intervention occurs, making it a preliminary step rather than an immediate objective.
