To reconcile client, caregiver, and staff reports in ABA assessment, preserve each informant, exact question, timeframe, setting, access method, authority, and confidence. Compare observable examples, valid opportunities, and what each person could know. Center the client's accessible communication, investigate differences without voting or averaging, and choose direct evidence that can clarify the clinical decision while retaining unresolved disagreement.

Ask matched questions

Use the same observable question, defined period, response options, and context prompts with each informant when comparison is intended. Allow accessible modes and additional examples. Record when a person cannot observe the setting or period rather than prompting a guess.

Preserve source knowledge

Document Mosi's direct experience and intent, the caregiver's routines and period observed, and staff exposure by setting and time. A confident answer can still cover a narrow sample. Multiple staff repeating one shared note may represent one evidence chain.

Also record whether each source witnessed the event directly, learned about it from someone else, or inferred it from an outcome.

Compare examples before labels

Translate often, refuses, fine, or anxious into described events, opportunities, supports, communication, partner response, duration, and impact. Different labels may describe the same event, while identical labels may refer to different topographies or thresholds.

Keep context-specific patterns

A response may occur at school and not at home because opportunities, supports, people, noise, tasks, health, or outcomes differ. Preserve these conditions. The goal is an accurate map, not forced agreement across environments.

Center accessible client input

Give Mosi a private direct route, AAC and language access, wait time, correction, pause, and withdrawal. Another person's report can add context but never authors Mosi's experience or automatically overrides a capable objection.

Plan clarifying evidence

Choose observation, records, measurement, health review, or another qualified source for the specific conflict. Define what pattern would support each explanation and when the review is mature. Retain unresolved differences in the final assessment.

Protect Mosi during assessment

For Mosi, preserve AAC and other effective communication, privacy, ordinary supports, food, water, bathroom, mobility, prescribed care, rest, and emergency help. Verify health and safety before interpreting behavior. Use applicable consent and assent processes, honor withdrawal during nonemergency participation, and route medical, mental-health, protective, or acute-risk concerns to qualified systems without waiting for routine assessment completion.

Build Mosi's evidence ladder

Move from the least intrusive evidence that can answer Mosi's question toward stronger methods only when uncertainty, decision value, risk, and feasibility justify it. Separate client report, proxy report, records, descriptive observation, measurement, structured comparison, and experimental evidence. State what each source can and cannot show, which conditions it covers, and what result would change the plan.

Explain the assessment status to Mosi

Use Mosi's preferred language and communication mode to explain the current question, completed evidence, missing contexts, health and safety boundaries, uncertainty, proposed next method, and possible decisions. Invite correction, disagreement, pause, and withdrawal where applicable. Meaningful participation supports fit. Agreement with the clinician's interpretation is never a condition for communication access or appropriate care.

Build Mosi's multi-informant evidence matrix

Create one versioned multi-informant evidence matrix for the home-school-clinic assessment. Include question, client priority, response class, settings, sources, access, health review, ordinary supports, consent and assent when applicable, privacy, sampling, opportunities, methods, comparisons, integrity, missingness, stops, adverse events, results, alternatives, uncertainty, authority, decision, client communication, revision, and next review.

Work through Mosi's example

Mosi, a caregiver, and a staff member each answer four matched questions, producing 12 source-labeled claims. Five describe a common pattern, four are setting-specific, and three conflict under the predeclared comparison rule. Report 5/12 common, 4/12 context-specific, and 3/12 conflicting claims. The three informants remain three sources; agreement counts never establish function or truth by majority vote. Preserve all planned and valid units, raw counts, denominators, source labels, access states, missing conditions, stops, corrections, versions, decisions, and open work. This fictional example demonstrates one assessment control. It supplies no universal threshold, diagnosis, functional relation, legal conclusion, treatment effect, or outcome guarantee.

Use Mosi's evidence for a bounded decision

Identify the exact decision and qualified owner before expanding assessment. For Mosi, document supporting and conflicting evidence, current protection, client preference, alternatives, further evidence, risk, feasibility, chosen method, decision, implementation test, accessible explanation, disagreement route, and review trigger. Choose the least burdensome adequate path and stop collection that cannot change action.

Review Mosi's evidence without causal shortcuts

For Mosi, show raw observations and denominators, representative coverage, direct and proxy sources, access, health context, missingness, comparisons, observer effects, alternatives, and uncertainty. Descriptive timing and co-occurrence support hypotheses. Functional claims require evidence suited to that claim and remain bounded to the tested response, participant, procedures, and conditions.

Address Mosi's main assessment risk

Averaging Mosi's report with two adults would give the adults twice the numerical weight and erase setting knowledge. Treating every difference as unreliability would miss real contextual variation. Review definitions, client meaning, health, access, sampling, method integrity, source independence, comparison, causal scope, and authority separately. Technical terminology cannot rescue a weak, inaccessible, or unsafe assessment. A familiar protocol never substitutes for individualized indication, competence, consent, assent, and stop rules.

Choose Mosi's next assessment action

Mosi selects the most important conflicting question, and the team plans accessible direct observation across the two settings where reports differ. Record qualified owners, current safeguards, evidence or referral tasks, assessment and plan versions, due dates, validation evidence, client communication, uncertainty, and next review. Preserve the original question, evidence, and decision when the account changes. A revision adds an auditable version instead of rewriting what was observed.

Apply current assessment sources to Mosi's method

For Mosi, the CASP public summary gives high-level context for ABA treatment of autistic people. The current BACB Ethics Code addresses competence, understandable communication, client involvement, consent and assent when applicable, medical needs, assessment, referral, intervention, risk, documentation, and evaluation for covered people. BACB has no separate organizational jurisdiction. The BCBA outline is examination content and supplies no case protocol or practice authority.

Keep functional-analysis claims bounded for Mosi

For Mosi's question, Hanley's functional-assessment review discusses the broader assessment process. The Hanley, Iwata, and McCord review examines systematic experimental functional analysis. Neither makes interview, descriptive co-occurrence, or an out-of-context result universal proof. Breaux and Smith offer assent-focused guidance in an evolving evidence base. ASHA supports continuous AAC access. SAMHSA routes danger or medical emergency in the United States to 911 or the nearest emergency room.

Close Mosi's assessment review

Review the multi-informant evidence matrix with Mosi, the responsible clinician, access and operational owners, and the specialists named in the manifest. Verify that methods remain proportionate, health and communication protected, evidence sources distinct, experimental claims bounded, uncertainty visible, and decisions within authority. Keep this page draft and noindex until every required review is complete.
