AAC funding through NDIS: a parent's plain-language guide

If you are reading this, you are probably trying to work out one of three things: whether your child can have an AAC device funded through their NDIS plan, what the assessment and trial process actually involves, or why the device you asked for got knocked back. This is the version we’d give a friend.

What “AAC funding through NDIS” really means

Augmentative and Alternative Communication (AAC) — the speech-generating tablet, the dedicated device, the PODD book, the high-quality switch — is fundable through NDIS, but it doesn’t sit neatly inside one budget. The hardware sits under Assistive Technology (AT). The trial, assessment, set-up, modelling and ongoing therapy sit under Capacity Building — Improved Daily Living (CB). The device and the support to use it well are two different conversations, and both have to be solid for AAC to actually take off in a family’s day.

A common failure mode: a device gets approved, arrives at home, sits in a drawer because no one got funded to teach the family how to model on it. The hardware on its own isn’t language — language is what happens when adults around the communicator use the system constantly. So in practice we always plan for both budgets at once.

The trial: why it matters and how it actually works

Before NDIS will fund a high-tech device (anything over a few thousand dollars typically), your speech pathologist needs to write an assistive technology assessment that recommends a specific device based on a trial period. The trial is not a formality. It is the bit of the process that protects the family from spending plan money on a device that doesn’t fit.

A real trial looks like this:

1. Two or three candidate devices identified by the speech pathologist, based on the communicator’s motor, sensory, visual, and language profile. Common contenders for kids are TouchChat with WordPower, LAMP Words for Life, Proloquo2Go, and Snap Core First.
2. Loaned hardware for two to six weeks. Some apps run on a family’s existing iPad; others need dedicated hardware. We coordinate loans through suppliers and the apps’ own free trials.
3. Modelling by the speech pathologist and by family/support people across real moments — not just during sessions. The goal is to see how the device functions in the kitchen, in the car, at bedtime, during a meltdown, at the playground.
4. A short comparison write-up that explains what worked and what didn’t on each candidate, and which one the AT assessment will recommend.

You can absolutely ask to extend a trial. If a kid is mid-shutdown for the first ten days, two weeks isn’t enough data; we will say so in the report and ask for more time.

What goes into the AT assessment report

NDIS planners read a lot of reports. The ones that work tie every recommendation to a clearly named functional goal and to the line items that funded the trial. Ours typically include:

• A plain-language summary of the communicator’s current communication (what they already do, what’s hard, what they want to do that they can’t yet).
• The candidate devices that were trialled, with the date range for each.
• Observations across at least three environments (home, school or kindy, community).
• The recommended device, mounting, case, accessories, and any warranties.
• A clear total cost broken out by item.
• The ongoing capacity-building support needed to use the device well — usually around 1:1 modelling for the family and any educators, plus regular review sessions.

We write reports plainly. If a planner has to translate clinical jargon to understand the recommendation, the recommendation is more likely to be cut.

Why AAC applications sometimes get knocked back

The most common reasons we see for AAC funding requests being delayed or reduced:

• The functional goal isn’t specific enough. “Improve communication” is too vague. “Be able to request a break independently across five environments by Q4” is reviewable.
• No documented trial. If the report just lists the recommended device without trial data, it reads as a wishlist rather than evidence.
• Cheap-device alternative not addressed. Planners are increasingly trained to ask “could a cheaper or lower-tech option meet the same goal?”. If the report doesn’t answer that question upfront — yes/no, and why — the file goes back for review.
• No capacity-building plan. A device with no modelling support attached looks high-risk.
• Stale assessment. Reports older than 12 months may be asked to be redone.

If a request has already been knocked back, it can usually be fixed with a targeted addendum rather than a brand-new application. We’ve done this enough that we can usually predict which of the above five issues was the trigger from a planner’s comments.

Self-managed, plan-managed, and agency-managed: does it change AAC funding?

Functionally, no — the application process is the same regardless of plan management. The practical differences are:

• Self-managed. You pay invoices directly and claim them back from the portal. Fastest turnaround, most admin. You can use any speech pathologist, whether registered or not.
• Plan-managed. Your plan manager handles the paying. You can still use registered or non-registered providers. Easiest for most families.
• Agency-managed. NDIS pays providers directly. You must use NDIS-registered providers. Speech Sprout is registered, so this is fine, but it can limit which device suppliers are available because not all are NDIA-registered.

If you’re agency-managed and the device supplier you want isn’t NDIS-registered, the workaround is usually to ask for a partial change to plan-managed for the AT category specifically.

Where AAC fits alongside other supports

AAC funding sits inside a wider plan that usually includes ongoing speech pathology under CB, sometimes OT for motor access needs (especially for switch users or eye-gaze systems), and sometimes psychology for advocacy and identity work. Reasonable AAC plans for a school-age kid across the first 12 months tend to look something like:

• AT — device, case, mount, warranty: one-off purchase from the AT budget
• CB — Improved Daily Living — speech pathology: 40–60 hours across the year for direct therapy, modelling, family training, and review
• CB — Improved Daily Living — therapy assistant: optional, can multiply the modelling exposure at lower per-hour cost for some families

We are happy to help you draft the goals and request specific hours when you go into a planning meeting — that conversation is part of standard practice for our clients.

What to ask your planner

If you’re heading into a planning meeting and AAC is on the table, three questions tend to make the conversation more productive:

1. “Can you confirm the AT category will be sufficient to fund the recommended device with accessories?” — this surfaces budget mismatches before they become a denial.
2. “What documentation do you need from us to support the AAC capacity-building hours?” — getting the format right up front avoids resubmissions.
3. “How would you prefer the report to handle alternative-option comparisons?” — different planners and LACs read reports differently; some want one paragraph, some want a full side-by-side. Asking up front means we can write the version they’ll actually use.

What we’ll do at our end

When a family at Speech Sprout decides to pursue AAC funding, the typical sequence is:

1. Free 15-minute call to map the question and timeline.
2. Initial sessions to establish where the communicator already is, what they currently use, and what we’d be aiming for.
3. Trial period across two or three candidate systems, with structured modelling at home and in sessions.
4. AT assessment written and submitted with the family, tied to the planning cycle.
5. Capacity-building hours costed and justified in the same report or a companion letter.
6. Once funding is in place, set-up, vocabulary customisation, family training, and the long, slow, beautiful work of building robust language access.

If your kid uses AAC, or you think they might benefit from it, the trial is rarely the wrong move. The risk of trying is small; the cost of not trying — measured in years of communication access — is enormous.
