29 | Getting an AAC Device & Understanding the Evaluation Process | Lydia McKay & Staci Dover
Intro
For families of non-speaking or minimally speaking children, Augmentative and Alternative Communication (AAC) can open powerful pathways to communication. But many parents wonder where to begin. How do you actually get an AAC device? What does the evaluation process look like? And who helps guide families through it?
In this episode of the Autism Family Resource Podcast, host Brian Keene continues a three-part series on AAC with Phoenix-based speech-language pathologists Lydia McKay and Staci Dover. Together, they walk through the steps involved in obtaining an AAC device and what families can expect during the evaluation process.
Their goal is to make the process less confusing and help families understand that AAC is simply another tool that supports communication.

Key Themes From the Conversation
Starting the AAC Process
One of the biggest challenges families face is simply knowing where to begin. In Arizona, families often start by contacting their insurance provider or reaching out to an AAC evaluation provider. If a child receives services through the Arizona Department of Developmental Disabilities (DDD), that system can help guide parts of the process.
Therapists may also help initiate referrals. Speech therapists, occupational therapists, and other clinicians can collaborate with families to complete the referral paperwork needed to begin the evaluation.
Understanding the AAC Evaluation
AAC evaluations are typically conducted by a team that includes a speech-language pathologist and either an occupational therapist or physical therapist. The reason for this team approach is simple: communication and motor access both matter.
While speech-language pathologists evaluate language and communication needs, occupational or physical therapists help determine how a child will physically access the device. This might include selecting icons with their fingers, using switches, or even eye gaze technology.
Finding the Right Device
During the evaluation, professionals use a process called “feature matching.” This means matching the features of different devices to the child’s individual needs.
For example, the team may consider:
• Button size and layout
• Vocabulary organization
• Access methods like touch, switch scanning, or eye gaze
• Visual supports and color coding
• The child’s motor abilities and positioning
Families play a critical role in this process because they know their child best. Their feedback helps the team determine which system feels most intuitive and usable in everyday life.
What Happens After the Evaluation
Once a device is recommended, the team prepares a detailed report and submits documentation to insurance and the child’s physician. A medical prescription is required both for the evaluation and for the device itself.
Because AAC devices are considered durable medical equipment, the approval process can take time. However, some providers may arrange temporary “loaner” devices so families can begin using AAC while waiting for the permanent device.
Training and family support are also essential. Once the device arrives, professionals typically provide coaching to help families learn how to incorporate AAC into daily routines.
Common Questions Parents Ask
How do I know if my child should try AAC?
AAC can be introduced at any age and does not require a child to meet specific prerequisites. If a child is struggling to communicate verbally, AAC can provide additional ways to express wants, needs, and ideas.
Will using AAC stop my child from talking?
Research and clinical experience consistently show that AAC does not prevent speech development. In many cases, AAC actually supports language development by giving children another way to practice communication.
Who helps choose the right AAC device?
AAC evaluations are typically completed by specialists, including speech-language pathologists and occupational or physical therapists. Families are an important part of the decision-making process, helping ensure the system fits their child’s needs and daily routines.
Why This Conversation Matters for Families
For many parents, AAC can feel overwhelming simply because the process is unfamiliar. Understanding how evaluations work and who helps guide the process can make the journey much more manageable.
When families have the right support and information, AAC can become a powerful communication tool that helps children express themselves, participate more fully in daily life, and build stronger connections with the people around them.
