Which of the following is a key purpose of data collection in a Behavior Intervention Plan?

• A. To document school events unrelated to behavior.
• B. To justify budget requests.
• C. To monitor progress and adjust interventions.
• D. To determine a student's IQ.

Answer: (C)

Data collection in a Behavior Intervention Plan is used to show whether the supports are working and to guide changes as needed. By recording how often the target behavior occurs, how long it lasts, how quickly it happens after a cue, and what happens before and after (the antecedents and consequences), you build a clear picture of the student’s behavior over time. This evidence lets you track progress toward specific goals, determine if the interventions are reducing problem behavior or increasing replacement behavior, and decide when to keep, modify, or intensify supports. If the data show meaningful improvement, you maintain the plan or ease supports as appropriate; if there’s little or no change, you revisit the plan’s components and adjust strategies, then continue collecting data to see the impact.

The other options don’t fit this purpose: documenting events unrelated to behavior doesn’t inform whether the plan works; using data to justify budget requests isn’t about changing the student’s behavior; and determining a student’s IQ isn’t part of implementing or evaluating a behavior plan.
