Down Syndrome AAC and Nonverbal IEP Goals

Your child understands everything happening in the classroom. She follows multi-step routines, laughs at jokes with perfect timing, and navigates social dynamics with her peers better than half the neurotypical kids. But because she can't produce intelligible speech, the school treats her as though she has nothing to say.

This is the gap that destroys educational outcomes for nonverbal and minimally verbal students with Down syndrome. The child's receptive language runs years ahead of her expressive output, and without a communication system written into the IEP, she sits in classrooms where nobody asks her opinion, nobody tests her knowledge, and nobody expects her to participate.

Why Speech Alone Is the Wrong Target

Oral hypotonia, dysarthria, and motor-planning dyspraxia can make intelligible speech difficult to produce, even when the child knows exactly what she wants to say.

Schools that write IEP goals focused exclusively on "will produce intelligible speech in 4 out of 5 trials" set the child up for years of documented failure. Speech therapy should absolutely continue, but expressive communication cannot wait for articulation to catch up. Augmentative and Alternative Communication (AAC) bridges that gap immediately.

AAC provides functional communication channels that can reduce frustration-driven behaviors.

What AAC Looks Like in Practice

AAC is not one device. It is a system of tools matched to the child's motor skills, cognitive profile, and communication contexts:

• Low-tech options: Picture Exchange Communication System (PECS), core vocabulary boards, visual choice boards, and communication books. These require no batteries, no charging, and no IT support from the school.
• Mid-tech: Single-message or sequential-message voice output devices (Big Mack, GoTalk). Useful for circle time participation, answering questions, and social greetings.
• High-tech: Speech-generating devices (SGDs) and tablet-based AAC apps (Proloquo2Go, TouchChat, LAMP Words for Life). These allow open-ended communication with robust vocabulary sets. Visual processing and memory can be relative strengths, but AAC access should be matched to the individual student's needs.
• Key word signing: Makaton, Signalong, or adapted ASL signs used alongside spoken language. Multimodal signing can enhance receptive understanding and support expressive communication while spoken language develops.

The IEP should specify which AAC modality the child uses, who programs and maintains devices, and where the device is available. A speech-generating device locked in the SLP's office does nothing for a child who needs to communicate during lunch, recess, and science class.

Writing AAC Goals That Schools Must Honour

Vague goals like "will use AAC to communicate needs" give schools room to do nothing measurable. Write goals with specific modality, context, and criteria:

Requesting: "Using her SGD with a minimum 40-cell core vocabulary display, [child] will independently navigate to and select vocabulary to make requests across 3 different school settings (classroom, cafeteria, playground) in 8 out of 10 opportunities over 3 consecutive data collection sessions."

Commenting and social interaction: "During structured peer activities, [child] will use her AAC device to initiate or respond to conversational exchanges with a peer at least 4 times per 20-minute session, as measured by SLP observation data."

Academic participation: "When called upon during whole-class instruction, [child] will use her AAC device to answer comprehension questions related to grade-level content (with modified complexity) with 70% accuracy across 5 consecutive sessions."

When written into the IEP, these goals make progress measurable. If the IEP team determines AAC is needed, the IEP must describe the device and related services or staff supports to be provided, and how progress toward each goal will be measured.

The Communication Plan: What Belongs in the IEP

A communication plan within the IEP should specify:

1. Primary and backup communication modes — what happens when the device battery dies or the tablet breaks. A paper-based core board should always be available.
2. Staff training requirements — identify which adults who work with the child (classroom teacher, paraprofessional, specials teachers, lunch monitors) need AAC modelling training. The SLP can provide this, and the IEP should name the training frequency when needed to implement the plan.
3. Modelling expectations — adults must model AAC use during instruction, not just expect the child to use it. Aided Language Stimulation means the teacher points to symbols on the board while speaking, showing the child how language maps to the system.
4. Device availability — the AAC system travels with the child to every setting, including field trips, assemblies, and after-school programs.
5. Programming schedule — who adds new vocabulary, how often the system is updated, and how curriculum-specific words get loaded before a new unit begins.

If the IEP team determines an AAC device or service is required as part of the child's special education, related services, or supplementary aids and services, IDEA requires the public agency to make it available under 34 CFR §300.105. Ask the team to consider the child's communication needs rather than treating speech-only use as a prerequisite.

When Schools Push Back

Common pushback and what to say:

"She's not ready for AAC yet." Ask what evidence supports that conclusion and whether a low-tech communication option could support the child while speech goals continue.

"We don't have trained staff." If staff training is needed to implement AAC supports in the IEP, ask that the IEP identify the training and who will provide it.

"She'll become dependent on the device and stop trying to talk." AAC provides a functional communication channel. If the IEP team identifies AAC as needed, the IEP can include it alongside speech-language goals so communication does not depend on intelligible speech alone.

The Down Syndrome IEP & Inclusion Toolkit includes an Accommodation Menu with AAC-specific provisions, AAC goal examples, and broader placement pushback scripts you can adapt when the school resists communication supports.

Multi-Country Notes

In England, Section F of the EHCP describes special educational provision. If AAC support is needed, ask for the provision to be specified clearly, including device access, staff training, and relevant SLP support.

In Ontario, Regulation 181/98 requires the IPRC to consider placement in a regular class with appropriate supports before recommending a special education class. Ask the committee to address what communication supports have been considered.

In Australia, the Disability Standards for Education 2005 require education providers to enable participation on the same basis through reasonable adjustments. AAC needs can be considered as part of those adjustments.

A nonverbal child with Down syndrome is not a child without language. She is a child whose language needs a different output channel. The IEP is where you make that channel a legal requirement.
