Question

Difficulty: easy. Skill: recognize. Type: data interpretation.

A BCBA reviews four sessions of stable baseline data followed by two overlapping intervention points for leaving the instructional area. The next decision depends on temporal-dimension measurement. What should the BCBA do? The case file includes 11 recent sessions, 2 implementers, and 1 setting.

A
Choose the measurement system that matches the behavior dimension and decision question in relation to learner's leaving the instructional area

Correct answer

B
Tell everyone to try harder and review the case next month
C
Treat the most recent data point as proof of the final conclusion
D
Base the decision on the descriptive label for leaving the instructional area and bypass temporal-dimension measurement

Explanation

Answer A

The clue is the combination of four sessions of stable baseline data followed by two overlapping intervention points, leaving the instructional area, and the required task: Temporal-dimension measurement. The case file includes 11 recent sessions, 2 implementers, and 1 setting. Choose the measurement system that matches the behavior dimension and decision question in relation to learner's leaving the instructional area is best because it answers that clue through measurement system selection instead of treating the scenario as a generic behavior problem. On exam items like this, name the decision point first, then eliminate options that rely on one report, a label, a familiar protocol, or an action that skips the relevant data check.

Why this question is hard

Clue
Key scenario clue

The clue is the combination of four sessions of stable baseline data followed by two overlapping intervention points, leaving the instructional area, and the required task: Temporal-dimension measurement. The case file includes 11 recent sessions, 2 implementers, and 1 setting.

Trap
Common trap

Vague delayed feedback does not create a measurable plan for improvement.

Next
If you missed it, review Measurement system selection

Then answer a few related scenarios before moving back to broad practice.

Why the other choices are weaker

B
Choice B

Vague delayed feedback does not create a measurable plan for improvement.

C
Choice C

A single point rarely supports a strong conclusion without considering trend, variability, and context.

D
Choice D

This is weaker because the label does not answer the Temporal-dimension measurement decision point or test Measurement system selection.
