AAC, a 30-Day Trial, and a Family That Wants Speech
Malik is 6;4, autistic, and minimally speaking: about eight spoken words, hand-leading, and pulling adults toward what he wants. Cognitive testing has not produced interpretable scores. Tantrums occur 10–12 times a day, mostly at transitions. His mother wants him to talk and is reluctant to try 'a machine'; his teacher wants a talker and reports that nothing else has worked. Your district has one iPad with TouchChat available for a 30-day trial, after which the special education director says it must be returned 'unless the family buys one.' Malik receives two 30-minute individual sessions a week plus 30 minutes of classroom consultation. No one in the classroom has used AAC before.
1. Is the director correct that the family must buy the device to keep it after the trial? What does the evidence say about readiness or prerequisite skills?

No-and the prerequisite question is settled too.
Funding. Under IDEA, if assistive technology is required for the child to receive FAPE, the district must provide it at no cost to the family (34 CFR §300.105; devices and services defined at §§300.5–300.6). A school cannot make access contingent on family purchase, and a 30-day trial is a clinical and funding step, not a legal basis for withdrawing a needed device. Medicaid or private insurance can be pursued in parallel; a denial or a slow approval does not transfer the obligation to the parents. If TouchChat is the appropriate system and Malik needs AAC, the district provides it.
Prerequisites. There are none. The evidence does not support requiring cause-and-effect training, picture discrimination, or a 'readiness' period before introducing an AAC system. Requiring them delays intervention and is itself a predictor of abandonment. What is evidence-based is feature matching-matching vocabulary organization, access method, and physical design to Malik's sensory, motor, and communication profile.
Also: AAC is multimodal. Keep supporting speech, gesture, and vocalization. The evidence shows AAC does not suppress speech and often supports it. His hand-leading is already communication-the goal is to give him a more efficient, more symbolic way to do the same job.
2. Write a defensible goal and data system for the 30-day trial. What has to be true for the data to mean anything?

Goal (function-based, not device-based):
'During 10 opportunities embedded in three daily routines (snack, centers, transition), Malik will independently use his AAC system to request, protest, or comment in at least 4 of 10 opportunities across three consecutive data days, with no more than one adult prompt per opportunity.'
Why this shape. 'Will use the device for 20 minutes' measures attendance, not communication. The functions matter-protest and comment are the jobs his tantrums are currently doing. Defining the prompt hierarchy in advance keeps the independence data honest.
Data system:
- Per-opportunity tally by communicative function, coded independent / gesture or vocalization / aided / prompted. This shows whether AAC is replacing the tantrum or just adding a step.
- Partner fidelity: how often adults model on the device (aided language input) during those routines, targeted at roughly one model per minute in the training phase. If partner fidelity is low, Malik's data are uninterpretable-you cannot tell whether the tool failed or the adults did.
- Tantrum frequency and duration by routine as a parallel measure. A baseline of 10–12 per day that has not moved by day 20 is a signal that the intervention, not the child, needs changing.
The decision point is day 10, not day 30. If he is not exceeding baseline by then, the likely culprits are the system, the vocabulary, or the partners-not readiness.
3. Malik's mother says, 'I don't want him to depend on a machine.' How do you respond, and what do you do concretely?
Read the worked answer
Take her seriously; she is describing a fear, not an obstacle.
That statement usually carries three worries: that AAC will replace speech, that it marks him as different, and that it is one more thing to manage. Address each with evidence and without lecturing.
- AAC does not stop speech from developing; for many children it supports it. The 30-day trial lets her see that for herself rather than take your word for it.
- Right now the 'machine' is his behavior-10 to 12 tantrums a day is an exhausting way to communicate, for him and for the family. AAC is a lower-cost way to do the same job.
- Start where she is. Offer a low-tech core board alongside the device during the trial, and ask what she would most like him to be able to say. Her answer becomes target vocabulary. That is how buy-in is built and how abandonment is prevented.
Concretely: invite her to one session, coach her in aided language input on her words ('more,' 'stop,' 'help,' 'all done'), and give her a two-week video-modeled plan with three specific routines to practice.
Do not make AAC contingent on her consent; do make her a partner in choosing the vocabulary and the trial's success criteria. Document her concerns, your response, and her agreement to participate.
