Keeping vocabulary organized in a consistent way can make AAC easier to learn and use. When important words stay in predictable locations, learners do not have to relearn where to find them each time the board changes. Research has found that symbol selection is faster when symbols remain in consistent locations rather than moving across exposures, which supports the idea that stable layouts can reduce search demands and support motor learning.

Keep high-use words in the same place #
Words used often, such as more, help, stop, go, want, and yes/no, should stay in consistent locations whenever possible. ASHA’s AAC guidance describes core vocabulary as common words used across contexts, and research on core vocabulary notes that these words tend to remain useful across environments, activities, and age groups. (ASHA)
Avoid moving buttons too often #
It can be tempting to reorganize the board frequently, especially when adding new vocabulary, but frequent changes can make communication harder. A stable layout helps learners build familiarity over time and can reduce frustration during daily use. Research on symbol location found an advantage for consistent placement, suggesting that changing locations can slow access. (PubMed)
Keep home and school aligned #
When a learner uses the device in more than one setting, it helps to keep key vocabulary in similar places across home, school, and therapy. ASHA’s early AAC guidance emphasizes educating caregivers and communication partners to create consistent, responsive communication environments, and school-based AAC guidance highlights the value of core vocabulary that carries across settings. (ASHA)
Use the same words across routines #
Try to keep important everyday words available across many parts of the day rather than limiting them to one activity page. Core vocabulary approaches are built around words that can be used across contexts, which helps learners use language more flexibly in real life. (ASHA)
Add new vocabulary carefully #
As the learner grows, the system should grow too, but new words should be added thoughtfully. A good rule is to keep the learner’s most familiar words stable while adding related vocabulary around them. This helps preserve what the learner already knows while making room for growth. That recommendation is supported by the consistent symbol location findings and by the broader AAC emphasis on reducing unnecessary operational demands. (ASHA Publications)
Make changes as a team #
If parents, teachers, therapists, and aides all support the learner, try to make vocabulary changes together. Shared decisions can help prevent unnecessary layout changes and keep the device more predictable for the learner. ASHA specifically highlights the role of family and community input in selecting AAC vocabulary, and its early AAC guidance stresses communication-partner education. (ASHA)
Helpful tips #
- keep high-use words in predictable locations
- avoid moving familiar buttons unless needed
- keep key vocabulary similar across home and school
- use core words across many routines
- add new words without disrupting familiar ones
- communicate layout changes with the full support team (ASHA)
Why consistency matters #
A consistent vocabulary layout can support faster access, less visual searching, and more confident communication over time. The goal is not to make the board rigid forever, but to let it grow in a way that protects what the learner has already learned. (PubMed)
