Assessment, Preference and Function
Assessment questions test records review, goal selection, preference assessment, reinforcer assessment, functional assessment, and data interpretation.
How to study for the BACB BCaBA exam
Treat each question as a supervised behavior-analytic service decision: define behavior, use data, stay within competence, implement function-based procedures, and coordinate supervision.
Core concepts
Concept 1
Assessment, Preference and Function questions reward the answer that follows the official source, the professional role, and the stated facts.
Exam cue: Identify the candidate role, client or public risk, source rule, calculation, or process step being tested.
Concept 2
The strongest answer identifies the rule, safety concern, ethical duty, calculation, client factor, or process step before acting.
Exam cue: Check whether the fact pattern is using a national standard, jurisdiction rule, handbook policy, or scenario-specific instruction.
Concept 3
Eliminate answers that ignore requirements, skip documentation, overreach the role, or treat convenience as the standard.
Exam cue: Choose the compliant and professionally scoped answer before the convenient or familiar answer.
Risk pitfalls and guardrails
Treating related standards as interchangeable without checking the source.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Skipping screening, documentation, authorization, sanitation, recordkeeping, or other required procedure.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Choosing an answer that protects convenience instead of client safety, public protection, or the stated professional duty.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Memory anchors
Records Review
Records review identifies medical, educational, historical, and contextual information at case outset.
Socially Significant Goal
Socially significant goals should matter to the client and stakeholders.
Client-Informed Goal
Client-informed goals reflect client priorities, dignity, and cultural context.
Skill Assessment
Skill assessments identify strengths, needs, and instructional targets.
Preference Assessment
Preference assessments estimate stimuli likely to function as reinforcers.
Functional Assessment
Functional assessment identifies variables related to problem behavior.
Indirect Assessment
Indirect assessment uses interviews, checklists, or rating scales.
Functional Analysis
Functional analysis experimentally tests variables that maintain behavior under qualified supervision.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.

Check-up Questions
Friday during a day-program observation, Liam, age 19, is working on requesting a break; records show medical sleep changes before hand flapping increased at school. What is the most defensible next step?
In Ethan's maintenance check for using a functional communication card, the team observes caregivers nominate goals that matter at home, but staff prefer easier clinic targets. Which action best fits behavior-analytic practice? The observation note was recorded at 4:35 p.m.
