AAC Evaluations

An augmentative and alternative communication (AAC) evaluation looks at how a person communicates and what tools and strategies may support communication across their daily environments. AAC includes a wide range of approaches, from gestures and symbols to speech-generating devices and communication apps. The goal is to match communication needs to features, not to promote any particular product.

Areas an AAC evaluation may consider:

Communication needs: what the person wants and needs to communicate, and with whom.

Current communication methods: how the person communicates now, including speech, gestures, signs, and any existing tools.

Symbol vs. text needs: whether pictures, symbols, text, or a combination best support the person.

Language considerations: vocabulary, language level, and how language is organized.

Direct selection: touching or pointing to make selections.

Switch access: using one or more switches to operate a device.

Scanning: selecting items presented in sequence, often with switches.

Eye gaze: using eye movements to make selections.

Motor access: the physical movements a person can use reliably.

Positioning: seating and positioning that support consistent, comfortable access.

Vocabulary needs: core and personalized vocabulary that fit the person's life.

Educational participation: communication demands in learning settings.

Communication environments: home, school, work, and community settings.

Communication partners: family, peers, teachers, and others who interact with the person.

Device and application feature matching: comparing options based on the features the person needs.

Trials: trying options in real activities where appropriate.

Training: support for the person and communication partners.

Implementation: putting the system into daily use.

Follow-up: reviewing and adjusting over time as needs change.
