To build an observable shaping criterion sequence, map Nico's current, intermediate, and terminal responses along one named dimension. For every version, define the eligible opportunity, active criterion, consequence, treatment of earlier functional responses, minimum exposure, advancement, hold, rollback, stop rule, qualified owner, and effective date. Prospective steps guide decisions while direct evidence and Nico's priorities support documented revision.
Anchor the sequence to Nico's outcome
Describe what stable lighting control makes possible for Nico in the theater. Define the terminal response with enough flexibility for normal variation, device settings, and an accessible preset.
Place criteria on one dimension
Order current and likely future values along the selected tolerance dimension. When a version changes duration and accuracy together, split it or document why the combined change is essential.
Define every active version
Give each criterion a unique identifier, boundary, unit, cue, opportunity, consequence, ordinary supports, minimum exposure, decision rules, owner, and dates. Preserve retired versions.
Handle earlier functional responses
State how prior approximations will be acknowledged, reinforced, redirected, or accepted when they remain useful communication or participation. Avoid sudden loss of every successful route without review.
Keep revision accountable
Direct staff can report patterns and Nico can request changes. A qualified clinician with case authority reviews the evidence and records advance, hold, rollback, redesign, or closure through the applicable process.
Use this sequence to build an observable shaping criterion sequence
Define Nico's outcome and dimension, write each version, test boundary scoring, preserve access and earlier useful forms, assign decision authority, explain changes accessibly, and retain the full history.
Build Nico's versioned shaping criterion sequence
Create one versioned shaping criterion sequence for the community-theater lighting-console review. Include Nico's priority, terminal response, current response, changing dimension, unit, natural cue, eligible opportunity, ordinary supports, first and later criteria, response values, reinforcement due and delivered, prompts, latency, correction, access, health, exposure, advancement, hold, rollback, stop, authority, effective dates, integrity, agreement, invalidity, missingness, withdrawal, direct experience, burden, generalization, maintenance, result, uncertainty, decision, correction, and review trigger. Store only decision-relevant information with role-limited access.
Validate Nico's shaping evidence
Have a second reviewer identify all six planned versions, reproduce 5/6 readiness, and locate the missing tolerance. For each version, verify cue, response dimension, boundary, unit, opportunity, consequence, earlier-response treatment, exposure rule, advancement, hold, rollback, stop, owner, and effective date. Test borderline fictional values and confirm the same version decision. Keep unused future criteria labeled proposed.
Keep Nico's measures and experience separate
Measure opportunity coverage, response values, criterion attainment, reinforcement integrity, prompt exposure, access, generalization, and maintenance with their own units. Ask Nico separately about clarity, effort, comfort, usefulness, burden, and whether assessment should continue. Accurate implementation can coexist with poor fit. A valued outcome can also improve without evidence that shaping alone produced the change.
Work through Nico's example
Nico's sequence contains six proposed criterion versions for holding a console slider within a chosen range. Five specify the response boundary, opportunity, consequence, advancement rule, and fallback. Version four lacks a range tolerance. Sequence readiness is 5/6, so version four is repaired before use. The later versions remain plans rather than evidence that Nico will need or complete them. Preserve every planned and valid unit, raw count, denominator, criterion version, response value, reinforcement event, prompt, latency, access state, integrity result, withdrawal, direct report, system failure, correction, and unresolved item. This fictional example demonstrates one assessment control. It offers no universal shaping sequence, step size, reinforcement rule, independence, mastery, generalization, diagnosis, trait, treatment effect, legal conclusion, coverage decision, payment promise, or outcome guarantee.
Address Nico's main assessment risk
A ladder drawn only as closer, longer, better invites different staff interpretations. Moving the criterion after one strong response creates a retrospective rule. Requiring the terminal response at every rehearsal converts a shaping sequence into repeated terminal-demand testing. Review goal relevance, response and dimension definitions, opportunity quality, ordinary supports, access, health, effort, prompts, reinforcement, partner behavior, context, client experience, authority, and causal scope separately. A clean graph cannot repair an inaccessible, burdensome, unwanted, or ethically unsound arrangement.
Keep shaping concepts and authority clear for Nico
The ABAI Basic Principles page supplies broad higher-education context. The BACB Test Content Outline includes shaping, differential reinforcement, measurement, prompting, generalization, maintenance, and evaluation as examination content. The current BACB Ethics Code addresses competence, client involvement, consent and assent when applicable, medical needs, positive reinforcement, risk, data, documentation, and evaluation for covered people. These sources create no individualized shaping plan or practice authority for Nico.
Distinguish gradual-change procedures for Nico
Vollmer's gradual-change review distinguishes shaping changes to response requirements from fading changes to stimuli, chaining changes to task components, and schedule thinning changes to reinforcement schedules. It is a conceptual review. Use the distinction to describe what changes in Nico's plan, while the qualified clinician selects and evaluates an individual procedure.
Read the small shaping comparison cautiously for Nico
Shane and colleagues compared a specified vocal-shaping condition with a broad reasonable-attempt condition for three autistic preschoolers and reported faster mastery under shaping in that study. The small, older, narrow comparison supplies no universal response form, step size, progression rule, or expected result for Nico.
Keep criteria and follow-up visible for Nico
For Nico's versioned shaping criterion sequence, McDougale and colleagues provide a reporting caution from 157 skill-acquisition articles in selected behavior-analytic journals. In Nico's review, remember that 26% lacked a specific mastery-criterion method, 58% lacked maintenance probes, and 1% were unclear about maintenance. This descriptive evidence supports transparent criteria and follow-up; it identifies no single best shaping threshold.
Preserve treatment scope, AAC, assent, and access for Nico
The CASP public summary supplies high-level ABA behavioral-health-treatment scope for autistic people, with licensed detail outside this page. ASHA's AAC portal says AAC users should always have access to their communication tools or devices. Breaux and Smith provide assent-focused practice guidance in an evolving evidence base. Follow governing sources and preserve communication, health care, food, water, bathroom use, mobility, rest, relationships, safety, and emergency help for Nico.
Choose Nico's next bounded action
Nico approves the chosen lighting range, asks to keep a preset button available, and wants each criterion change explained before the next rehearsal. Record the qualified owner, supporting evidence, effective date, current criterion, ordinary supports, health and access state, implementation check, accessible explanation, disagreement route, and reassessment trigger. Preserve the original assessment when responses, criteria, people, systems, tasks, health, or priorities change. A new arrangement creates a dated version rather than an error in Nico's earlier performance.
Close Nico's shaping review
Review the versioned shaping criterion sequence with Nico, the qualified behavior analyst, relevant partners, access owners, and specialists named in the manifest. Confirm that each criterion and denominator is reproducible, response shaping stays separate from prompting, fading, chaining, and schedule changes, AAC and basic access remain protected, health and motor questions stay with qualified professionals, and conclusions remain bounded to the sampled response, task, people, and context. Keep this page draft and noindex until every required review is complete.
