Separate Ability, Opportunity, and Support in ABA

To separate ability, opportunity, and support in ABA assessment, define the response and accessible conditions, then measure whether valid opportunities occurred, required supports were ready, and the person responded under those conditions. Keep partner behavior and system access visible. Absent opportunity never proves inability, and performance with ordinary chosen supports can demonstrate useful ability without requiring unsupported independence.

Define a planned opportunity

Specify the event the plan expects, including place, item, staff availability, timing, and client choice. Planned events help evaluate system preparation. They remain different from actual eligible opportunities when the relevant situation never occurs.

Define a valid opportunity

State the materials, natural cue, accessible communication, safety, privacy, time, and partner conditions needed. Record why a planned event was absent, invalid, or interrupted. Keep these conditions in operational metrics instead of client-performance denominators.

Define support readiness

List Haru's AAC, visual aid, mobility access, money tool, wait time, prompting agreement, sensory support, and partner response. Measure whether each was available and usable. A support present in a bag or device menu may still be inaccessible at the moment.

Measure supported ability

Within valid supported opportunities, record the response, accepted forms, help, corrections, latency, completion, burden, and outcome. Keep levels of support descriptive. Avoid treating fewer prompts as inherently better when Haru prefers or needs a stable aid.

Measure partner and system behavior

Track whether partners wait, recognize communication, provide the item or clear information, honor a stop, and repair barriers. A client response without an effective partner outcome can make the routine unusable despite apparent skill performance.

Use three linked decisions

Opportunity findings guide scheduling or environment; support findings guide access and partner preparation; performance findings can guide chosen teaching or retained assistance. Review all three with Haru before changing the goal, fading a support, or claiming independence.

Protect Haru's communication and health context

For Haru, keep AAC and other effective communication, assent and withdrawal when applicable, privacy, ordinary supports, food, water, bathroom, mobility, prescribed care, rest, and emergency help available. Record health and access conditions before interpreting performance. Suspected medical, mental-health, sensory, or safety issues go to the qualified route; a behavioral hypothesis never replaces needed care.

Build Haru's evidence ladder

Move from the least intrusive evidence that can answer Haru's question toward stronger methods only when the decision, uncertainty, risk, and likely value justify it. Separate client report, proxy report, records, descriptive observation, measurement, structured comparison, and experimental evidence. For each rung, state what it can show, what it cannot show, who may use it, and which evidence would change the conclusion.

Explain the reasoning to Haru

Use Haru's preferred language and communication mode to explain the question, evidence sources, proposed comparisons, privacy, current support, uncertainty, and possible decisions. Invite correction and disagreement. Describe why another method may or may not be needed. Meaningful participation is evidence for clinical fit; agreement is never coerced or treated as a condition for access to appropriate care.

Build Haru's ability-opportunity-support matrix

Create one versioned ability-opportunity-support matrix for the community purchase routine. Include the client-priority decision, question, response class, topographies, contexts, sources, health and access review, ordinary supports, opportunities, comparisons, missingness, evidence strength, alternatives, uncertainty, safety, authority, chosen method, result, decision, communication, effective dates, revision, and next review. Preserve original and superseded reasoning.

Work through Haru's example

Haru has 24 planned purchase opportunities. Twenty occur; four stores are closed or the item is unavailable. Required communication and visual supports are ready in 18 of 20 actual opportunities, and Haru completes the selected purchase step in 14 of 18. Report opportunity coverage as 20/24, support readiness as 18/20, and supported performance as 14/18. Preserve all planned and valid units, raw counts, denominators, source labels, access states, missing conditions, conflicts, corrections, versions, decisions, and open work. This fictional example demonstrates one clinical-reasoning control. It supplies no universal threshold, diagnosis, functional relation, legal conclusion, treatment effect, or outcome guarantee.

Use Haru's evidence for a bounded decision

Before collecting more data, identify the exact decision and qualified owner. For Haru, document supporting and conflicting evidence, current protection, client priority, alternatives, further evidence, feasibility, risk, decision, implementation test, accessible explanation, disagreement route, and review trigger. Choose the least burdensome adequate method rather than the most elaborate available method.

Review Haru's results without causal shortcuts

For Haru, show raw observations and denominators, representative coverage, direct and proxy sources, access, health context, missingness, comparisons, alternative explanations, and uncertainty. Descriptive timing and co-occurrence support hypotheses. Functional claims require evidence suited to that claim and remain bounded to tested responses and conditions. Treatment change after intervention alone never proves the hypothesized mechanism.

Address Haru's main reasoning risk

Using 14/24 as Haru's skill score would treat four absent events and two missing-support events as inability. Using 14/18 alone would hide system readiness. The matrix reports all three stages. Review definitions, client meaning, health, access, sampling, source independence, comparison, measurement, causal scope, and authority separately. Precise language cannot rescue a weak or unsafe assessment. A familiar concept label cannot substitute for direct evidence about this person, response, context, and decision.

Choose Haru's next clinical action

Haru's partners correct the two support failures, retain his chosen tools, and review the four valid supported nonresponses for burden, preference, and specific learning needs. Record qualified owners, current safeguards, referral or evidence tasks, plan and assessment versions, due dates, validation evidence, client communication, uncertainty, and next review. Preserve the prior question and hypothesis when evidence changes. A revised clinical account adds an auditable version rather than rewriting what the earlier team believed or observed.

Apply current clinical sources to Haru's reasoning

For Haru, the CASP public summary gives high-level context for ABA treatment of autistic people. The current BACB Ethics Code addresses competence, understandable communication, client and stakeholder 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 claims bounded for Haru

For Haru's question, Hanley's functional-assessment review discusses the broader assessment process, while the Hanley, Iwata, and McCord review examines systematic experimental functional analysis. Neither source makes one interview, descriptive co-occurrence, or an out-of-context result universal proof. The ABAI basic-principles page is higher-education content. ASHA supports continuous AAC access. SAMHSA routes danger or medical emergency in the United States to 911 or the nearest emergency room.

Close Haru's clinical-reasoning review

Review the ability-opportunity-support matrix with Haru, the responsible clinician, access and operational owners, and the specialists named in the manifest. Verify that the question remains useful, evidence proportionate, health and communication protected, concepts precise, uncertainty visible, and decisions within authority. Keep this page draft and noindex until every required review is complete.
