To measure shaping progress across criterion changes, assign every opportunity to the active version of Orla's response criterion. Report the response-value distribution, criterion attainment, reinforcement, prompts, latency, errors, withdrawal, invalidity, exposure, and direct experience within that version. Mark transition dates and decision reasons. Preserve separate denominators because 80 percent at an easier criterion and 70 percent at a harder criterion answer different questions.
Give each criterion a version
Store a version identifier, threshold, unit, effective date, owner, reason, ordinary supports, and decision rule with every opportunity. Never infer the active criterion from the score after data collection.
Report response values and attainment
Show the underlying measurement distribution alongside met or unmet criterion. Attainment supports the active decision rule, while response values permit comparison across version boundaries.
Preserve exposure
Report valid opportunities, planned opportunities, sessions, dates, and time at each version. Ten opportunities in one day and ten across a month provide different experience histories.
Keep prompts and reinforcement visible
Record prompt exposure, consequence due and delivered, latency, correction, and unplanned partner help. Apparent progress can reflect a procedure change rather than movement under the natural cue.
Pair performance with practical value
Measure scan completion, effort, delays, access failures, errors, and Orla's rating separately. A narrower alignment criterion may add precision while reducing usefulness.
Use this sequence to measure shaping progress across criterion changes
Version Orla's criteria, collect the same response unit, report within-version attainment and exposure, audit support and reinforcement, inspect experience, and state only the progress claim the series supports.
Build Orla's cross-criterion shaping progress table
Create one versioned cross-criterion shaping progress table for the volunteer-mailroom scanner review. Include Orla'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 Orla's shaping evidence
Reproduce Orla's 8/10, 7/10, 6/10, and pooled 21/30 = 70%. Verify each opportunity's version, criterion, response value, validity, reinforcement, prompt, latency, error, withdrawal, device state, and date. Plot the same underlying response unit across versions when feasible, then overlay criterion boundaries. Confirm that the summary distinguishes attained criterion, changing response dimension, operational success, and Orla's experience.
Keep Orla'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 Orla 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 Orla's example
Orla's three scanner-alignment versions each have ten valid opportunities. Attainment is 8/10 at the broad zone, 7/10 at the middle zone, and 6/10 at the narrow zone. The pooled result is 21/30, or 70%, yet the denominator contains three different thresholds. Report 8/10, 7/10, and 6/10 with their response distributions and exposure rather than treating 70% as one stable performance level. 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 Orla's main assessment risk
A rising average response value can coexist with lower criterion attainment after the threshold changes. A pooled percentage can also make a rollback look like sudden improvement even when the underlying response distribution stays similar. 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 Orla
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 Orla.
Distinguish gradual-change procedures for Orla
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 Orla's plan, while the qualified clinician selects and evaluates an individual procedure.
Read the small shaping comparison cautiously for Orla
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 Orla.
Keep criteria and follow-up visible for Orla
For Orla's cross-criterion shaping progress table, McDougale and colleagues provide a reporting caution from 157 skill-acquisition articles in selected behavior-analytic journals. In Orla'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 Orla
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 Orla.
Choose Orla's next bounded action
Orla prefers the middle zone because it completes scans reliably with less corrective repositioning, so the team reviews practical benefit before narrowing further. 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 Orla's earlier performance.
Close Orla's shaping review
Review the cross-criterion shaping progress table with Orla, 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.
