Assessment Glossary

Start with the referral question

A behavior assessment is a broad process for defining a concern, gathering evidence, evaluating context, and informing decisions. A functional behavior assessment focuses on variables related to why behavior occurs and persists. Neither label identifies a single required procedure.

Write the question before selecting the tool. Is the team defining a response, describing a pattern, evaluating skills, identifying preferences, testing a functional hypothesis, checking health or environmental contributors, or deciding whether another professional should assess?

The BACB BCBA Test Content Outline includes records review, interviews, descriptive and functional assessment, preference and reinforcer assessment, cultural variables, referral, and interpretation as examination content. It is not a universal assessment sequence or independent authority to practice.

Gather indirect and historical evidence

An indirect assessment gathers information without directly observing the target response in the relevant situation. A behavioral interview asks for observable examples, context, communication, health, strengths, priorities, and uncertainty. A records review examines existing clinical, educational, medical, payer, incident, and progress information for a defined purpose.

Indirect evidence can reveal settings and questions worth observing. Recall, definitions, informant experience, and changing conditions affect it. Preserve who reported each fact, which period and setting it covers, and whether it is observation, interpretation, or client report.

Observe patterns in context

Direct observation records defined events as they occur. A descriptive assessment examines naturally occurring relations among antecedents, responses, and consequences without experimentally arranging them.

An ecological assessment looks broadly at routines, people, settings, access, demands, health, and environmental fit. A scatterplot assessment displays whether defined events cluster across time blocks. It can guide closer observation while leaving function unresolved.

Suppose fictional clinician Mara observes 12 eligible transitions across home and a community program. The defined response occurs in 5 of 12. The person's AAC is available in 10 transitions, a visual preview in 7, and the chosen break route in 8. These supports overlap. The counts identify conditions to examine; they do not prove which variable caused the response.

Distinguish analysis formats

A functional analysis experimentally arranges and compares conditions to test a functional relation. A brief functional analysis compresses exposure or sessions. A trial-based functional analysis embeds short control and test trials within routines.

A synthesized contingency analysis tests a combined contingency based on assessment information. The result supports the tested synthesis under those conditions; it does not isolate each component unless the design does so.

Hanley's functional-assessment review discusses indirect, descriptive, and experimental methods and practical considerations. Method selection still depends on risk, setting, competence, resources, medical factors, client involvement, and the decision the evidence must support.

Experimental work changes conditions and can evoke behavior. Define stop rules, medical and safety boundaries, staffing, protective access, communication, assent and withdrawal response, treatment availability, and oversight before starting. Never remove AAC or essential health and safety support to construct a test.

Assess preferences, reinforcers, and competing stimuli

A reinforcer assessment tests whether contingent access to an event strengthens or maintains a defined response. Preference alone identifies a candidate.

A competing stimulus assessment evaluates engagement and responding when candidate stimuli are available, often to inform support for behavior maintained by nonsocial reinforcement. Define access, response, observation window, comparison, and safety limits.

A curriculum-based assessment samples performance against a defined skill sequence or instructional framework. It can help organize teaching priorities while leaving diagnosis, functional relations, and person-centered value to separate evidence and decisions.

The ASHA AAC portal says AAC users should always have access to their communication tools or devices. Preserve direct communication during interviews, observations, choices, experimental conditions, and result review.

Build an interpretation statement

Every assessment conclusion should name:

• referral question, person, setting, period, and decision owner
• operational definitions, eligible opportunities, missingness, and data reliability
• methods, informants, direct client input, supports, conditions, and changes
• result, comparison, uncertainty, alternative explanations, and scope
• medical or interdisciplinary referrals, safety limits, and next evidence step

State whether evidence is descriptive, predictive, experimental, or decision-supporting. A functional hypothesis, assessment score, or preference result should never travel into a new setting or purpose without checking fit.

When observer scores drive a clinical decision, define how observers were trained and calibrated. Sample agreement across relevant conditions and report it separately from the measured behavior or implementation. High agreement can support confidence that observers scored similarly, while leaving construct validity, sampling bias, clinical meaning, and treatment effectiveness as separate questions.

Preserve raw observations so later reviewers can trace each conclusion back to the evidence and its conditions.
