    Let's review and break down a BCBA® mock exam question about measurement techniques in ABA, specifically percentage of opportunity. PTB co-founder Dana Meller explains how to calculate the percentage of opportunities where the behavior is exhibited and why this method is superior to rate, count, and interval recording in certain situations. Refer to BCBA® Task List (5th ed.) Section C-3: Measure occurrence (e.g., count, frequency, rate, percentage).
