To plan an AAC-inclusive communication assessment, preserve continuous access to the person's communication systems and identify every aided and unaided mode, access method, vocabulary, positioning need, partner skill, and backup. Measure effort, message recognition, repair, and partner response across meaningful settings. Protect consent, assent, privacy, health, and device ownership. Qualified SLP and AAC expertise should lead AAC-specific evaluation and recommendations.
Inventory all communication systems
List Theo's device, apps, pages, symbols, signs, gestures, writing, speech, partner-assisted scanning, and low-tech backups. Record ownership, configuration, current use, and which modes work for selection, refusal, repair, pain, and emergencies.
Verify physical and sensory access
Check positioning, mounting, reach, switch or eye-gaze calibration, visual and auditory access, charging, connectivity, fatigue, lighting, noise, and mobility. Test access in each setting instead of assuming clinic readiness transfers.
Check vocabulary and navigation
Confirm that Theo can reach words and messages relevant to the planned activities, including stop, no, discomfort, help, correction, and topics he selects. Preserve personalized language and avoid replacing it with staff-preferred vocabulary.
Assess partner readiness
Ask partners to wait, recognize modes, provide access, respond to messages, check meaning, repair breakdowns, and use backups. Measure their steps separately. A partner error never becomes evidence of Theo's limited communication.
Plan outages and privacy
Define backup activation, device failure, updates, charging, storage, transportation, access permissions, recording, data ownership, retention, and deletion. Keep protected communication content limited to the assessment purpose.
Coordinate qualified evaluation
Route AAC feature matching, language organization, speech-language diagnosis, motor access, vision, hearing, and medical questions to qualified professionals. ABA observation can contribute bounded context and partner data within scope.
Protect Theo's communication access
For Theo, preserve AAC and every reliable communication mode, language and interpreter access, privacy, ordinary supports, adequate wait time, food, water, bathroom, mobility, prescribed care, pain response, rest, relationships, and emergency help. Verify health, hearing, vision, motor, and safety questions through qualified roles. Use applicable consent and assent processes and honor refusal or withdrawal during nonemergency participation.
Build Theo's communication-evidence ladder
Begin with Theo's direct accessible report, priorities, modes, languages, partners, and ordinary routines. Add source-labeled interviews, records, natural samples, structured probes, speech-language or AAC assessment, hearing or medical evidence, and behavior-analytic observation only as needed. Keep message, language, speech, AAC access, partner response, behavioral function, diagnosis, decision, and outcome separate.
Explain the assessment to Theo
Use Theo's preferred language and mode to explain the question, lead role, contributors, activities, tools, interpreter, recording, privacy, access, supports, prompts, risks, stop route, possible decisions, and uncertainty. Invite questions, correction, refusal, pause, and withdrawal. Assessment participation never requires speech, eye contact, one motor response, or surrender of AAC.
Build Theo's AAC-inclusive assessment access plan
Create one versioned AAC-inclusive assessment access plan for the clinic and community communication review. Include client priority, question, lead, contributors, qualifications, source, languages, modes, AAC, interpreter, partner, setting, opportunity, message, response window, partner response, access, health, consent and assent when applicable, supports, prompts, methods, tools, integrity, raw data, invalidity, missingness, uncertainty, decision, referral, revision, and review trigger.
Work through Theo's example
Theo's plan reviews 12 scheduled assessment blocks. Ten have the primary AAC system positioned and functioning, and all 12 have a tested low-tech backup. The same two blocks that lack primary-system readiness also lack current vocabulary for the planned activity. Report 10/12 primary-system readiness, 12/12 backup readiness, and 10/12 activity-vocabulary readiness. Because the block-level register confirms that the two gaps overlap, two blocks are held as access gaps rather than client nonresponse. If the gaps occurred in different blocks, the three totals alone would not reveal how many blocks were ready. Preserve planned and valid units, raw counts, denominators, languages, modes, source labels, partner actions, access states, refusals, invalidity, corrections, versions, decisions, and open work. This fictional example demonstrates one communication-assessment control. It supplies no universal language level, diagnosis, behavioral function, legal conclusion, treatment effect, or outcome guarantee.
Use Theo's evidence for a bounded decision
Identify the exact decision and qualified owner before expanding assessment. For Theo, document direct and conflicting evidence, client priority, language and mode, AAC, access, health, partner, context, alternatives, burden, further evidence, chosen action, accessible explanation, disagreement route, and review trigger. Choose the least burdensome adequate path and stop collection that cannot change action.
Review Theo's data without causal shortcuts
For Theo, show raw messages or responses and denominators, representative opportunities, direct and proxy sources, languages, modes, AAC, partners, supports, prompts, access, health context, invalidity, missingness, and uncertainty. Observed communication describes sampled conditions. It never proves diagnosis, behavioral function, internal intent beyond the person's communication, or universal performance.
Address Theo's main assessment risk
Removing Theo's device to test speech would erase communication access and change the assessment. A backup stored in a cabinet but never tested offers little protection. The plan makes system readiness observable. Review definitions, client meaning, language, mode, AAC, interpreter, partner behavior, access, health, method fit, tool rules, sampling, causal scope, and authority separately. A test score cannot repair invalid language conditions or inaccessible administration. Technical labels never override Theo's current communication.
Choose Theo's next assessment action
Theo chooses the backup layout, adds two activity words, and asks both communication partners to demonstrate the repair routine before assessment resumes. Record qualified owners, current supports, method and tool versions, evidence or referral tasks, due dates, validation, client communication, uncertainty, decision, and next review. Preserve original observations when the account changes. A later assessment adds an auditable version instead of rewriting what Theo communicated under earlier conditions.
Apply current speech-language and AAC sources to Theo
The ASHA Autism portal describes comprehensive speech-language assessment for autistic people across speech, language, feeding and swallowing, and AAC as relevant. The ASHA Spoken Language Disorders portal describes comprehensive, culturally and linguistically appropriate assessment and consideration of language difference and disorder. For Theo, qualified SLP, AAC, hearing, medical, motor, educational, and other professionals lead conclusions within their current authority and competence.
Protect multilingual validity for Theo
The ASHA Multilingual Service Delivery portal discusses case history, samples, observation, dynamic assessment, interpreters, and collaboration. It advises against reporting standardized scores when the person is outside the normative sample and against deriving a standard score from translated items unless that version is validated and used as directed. For Theo, record the language, mode, examiner, interpreter, method, and validity limit of every result.
Keep AAC available for Theo
ASHA's AAC portal states that AAC users should always have access to their tools or devices. Breaux and Smith offer assent-focused guidance in an evolving evidence base. Preserve Theo's AAC, reliable modes, privacy, ordinary supports, and accessible ways to consent when required, assent when applicable, decline, pause, stop, correct an interpretation, and change a communication preference.
Keep education and ABA sources in scope for Theo
For Theo's school-specific question involving a child evaluated under IDEA Part B, 34 CFR 300.304(c)(1)(ii) requires assessment in the child's native language or other communication mode and in the form most likely to yield accurate information unless clearly infeasible. This education rule is setting-specific. The BCBA outline is examination content. The BACB Ethics Code governs covered people and gives BACB no separate organizational jurisdiction. The CASP public summary supplies high-level ABA treatment scope for autistic people.
Close Theo's communication review
Review the AAC-inclusive assessment access plan with Theo, the SLP or other clinical lead, the behavior analyst when involved, access and operational owners, and the specialists named in the manifest. Verify that languages and modes remain represented, AAC stays available, methods and conclusions remain within scope, partner and system conditions remain visible, and uncertainty is clear. Keep this page draft and noindex until every required review is complete.
