Question
Difficulty: medium. Skill: apply. Type: data interpretation.
A referral says a 5-year-old learner engages in leaving the work area, but the only information available is escape follows the response on most trials, and task difficulty changed last week. Across 8 sessions in service week 48, one observer recorded 16 minutes of observation in the early intervention clinic. Before selecting goals or procedures, the BCBA should:
AChoose the intervention from the response topography without checking the maintaining variables.
BSkip baseline because the team already agrees the behavior is serious.
CReview level, trend, variability, overlap, and implementation notes before deciding whether the data support a change.Correct answer
DPick a replacement skill because it is socially desirable, even if it does not contact the same outcome.

Explanation
Answer CThe decision point is: Does the answer gather the assessment information needed before selecting intervention? This item specifically tests Assessment-data interpretation for socially significant goals through a applied-client-service-scenario format. The key clue is in the stem facts: A referral says a 5-year-old learner engages in leaving the work area, but the only information available is escape follows the response on most trials, and task difficulty changed last week. Across 8 sessions in service week 48, one observer recorded 16 minutes of observation in the early intervention clinic. Before selecting goals or procedures, the BCBA should: Answer C is strongest because it follows this rule: Review level, trend, variability, overlap, and implementation notes before deciding whether the data support a change. It fits the source-backed rule without announcing that rule in the stem. The tempting mistake is to choose a shortcut before the scenario's prerequisite is satisfied. This choice weakens the data basis for the decision. A defensible answer must check whether the measurement, observation, or visual-analysis evidence supports the next step. Exam move: name the missing prerequisite first, then eliminate answers that jump to a label, a familiar procedure, a single data point, or an undocumented action.

Why the other choices are weaker
AChoice AThis choice weakens the data basis for the decision. A defensible answer must check whether the measurement, observation, or visual-analysis evidence supports the next step.
BChoice BThis choice weakens the data basis for the decision. A defensible answer must check whether the measurement, observation, or visual-analysis evidence supports the next step.
DChoice DThis choice treats a procedure or response form as enough. The scenario still requires matching the action to function, assessment results, or the decision rule.
