One hundred percent accuracy from few ABA opportunities means every scored response in a small eligible set met the definition. Report the count, such as 3 of 3, because the percentage alone hides precision and exposure. Review independence, difficulty, context, prompting, and opportunity quality. A perfect small sample can support a next probe while remaining insufficient evidence of durable mastery or generalization.
Always pair percentage with counts
Write 3 of 3, 9 of 12, or the applicable numerator and denominator beside every accuracy percentage.
Describe opportunity quality
Record novelty, difficulty, natural relevance, partner, setting, and whether the response mattered outside the teaching routine.
Separate independent and prompted performance
Use distinct fields and preserve prompt level, latency, and any response supplied after help.
Prevent favorable stopping
Define session or opportunity completion before results so early correct responses cannot shrink the denominator.
Choose the next evidence step
State whether the small sample releases a larger probe, more teaching, generalization review, or no change.
Build Ben's small-denominator accuracy review
For the 100 percent accuracy few opportunities ABA question, create a versioned small-denominator accuracy review. Preserve the target, client-selected purpose, operational response, accepted communication forms, eligible opportunities, observation time, numerator, denominator, independence, prompts, context, partners, materials, criterion, teaching history, generalization, maintenance, access, safety, decision owner, actual transition, and follow-up. Another qualified reviewer should be able to reconstruct Ben's result without guessing what counted.
Work through Ben's mastery example
Ben independently completes 3 of 3 navigation opportunities during one lesson, or 100%. In a later session with varied icons and positions, he completes 9 of 12, or 75%. The first result was calculated correctly, yet its three familiar opportunities did not represent the broader task conditions. Show raw counts and every relevant cell or date before adding percentages. This fictional school device-navigation program example illustrates one decision pattern and does not establish a universal mastery level, observation count, probe schedule, treatment plan, or transition rule.
Audit Ben's source evidence
Ben's review stores both numerators and denominators, icon sets, prompt status, device access, response latency, partner, and task order. It shows the 3-of-3 session and does not replace it with the later pooled result. The audit also checks definition and criterion versions, data-entry history, invalid and missing states, opportunity selection, observer agreement when useful, graph or table calculations, prompt coding, teaching integrity, and corrections. Unresolved discrepancies stay visible and pause any transition that depends on them.
Address Ben's main decision risk
A perfect score can reward reducing opportunities or presenting only familiar items. Ben's program predefines eligible opportunities and prevents staff from ending a session early because the first responses look favorable. A dashboard can calculate and surface evidence. It cannot decide that a skill is meaningful, safe, generalized, maintained, or complete. Those judgments belong to the person and qualified roles under the applicable plan and authority.
Choose Ben's next step
The next step might add meaningful opportunities, probe novel examples, or review whether three trials are all the setting naturally offers. The decision reflects the skill and burden rather than a universal minimum. Record the decision, rationale, owner, date, support plan, and review trigger. Keep acquisition, generalization, maintenance, and clinical value as separate evidence so one favorable state cannot silently satisfy another.
Protect Ben's access and choice
Keep Ben's AAC, interpreters, mobility, food, water, bathroom use, prescribed care, health support, rest, relationships, and emergency help available. Ordinary communication, sensory, visual, and mobility supports remain present during teaching and probes unless the defined question concerns one support and qualified review approves the safe comparison. Use accessible consent and assent processes when applicable and respond to withdrawal, dissent, or distress.
Apply current sources to Ben's review
Ben's page applies mastery research cautiously because study-specific criteria cannot set one correct opportunity count for every client and skill. The BACB ethics hub and CASP public summary provide professional context, while the BCBA Test Content Outline identifies examination content on measurement and skill acquisition. The WWC handbook supplies research-design context. A mastery and maintenance review, a replication of criterion effects, and a preliminary criterion analysis show that criterion details can affect later responding and remain incompletely standardized. A generalization case study and ABA instructional-design paper address purposeful planning. ASHA supports continuous AAC access.
Rehearse Ben's decision rule
Test the small-denominator accuracy review with fictional cases containing 0 of 0 opportunities, a perfect 2 of 2, unequal session denominators, prompted success, a missing session, a weak context, an overdue probe, and a system-access failure. Confirm that statuses, denominators, holds, calculations, and review routes behave as intended. Store expected outputs, software version, reviewer notes, and the correction log before the rule touches live data.
Close Ben's mastery review
Review the small-denominator accuracy review with Ben, the responsible clinician, and other specialists required by the target. Preserve raw data, active criterion, teaching context, client input, access and safety evidence, generalization, maintenance, qualified decision, actual transition, exceptions, and later outcomes. Keep the page draft and noindex until every manifest-named review is complete.
