EXECUTIVE FUNCTION DATA COLLECTION

Record a tally mark each time the target behavior occurs during the observation period. Best for discrete behaviors with distinct start and stop points.

Record the start time when behavior begins and end time when it stops. Calculate total duration. Best for prolonged behaviors (e.g., tantrums, off-task episodes).

Record time elapsed between teacher instruction/cue and student initiating response. Best for measuring prompt compliance and task initiation delays.

Check at predetermined intervals (e.g., every 2 mins) whether behavior is occurring EXACTLY at that moment. Mark (+) for occurrence, (-) for non-occurrence.

Mark (+) if the target behavior occurs at ANY point during the specified interval. Overestimates behavior duration; best for behaviors targeted for reduction.

Record response level for each trial/opportunity using prompt hierarchy key. Calculate: (Independent Correct / Total Opportunities) × 100.
