Symbols for object nouns, action verbs, and a few other things look fairly similar when represented in various AAC symbol sets. From a learning perspective, it makes sense to have a consistent symbol type across the expressive tools that the client will use.(See the Beukelman & Mirenda text for 5 assessment tasks that help us figure this out.) That’s why it is a best practice to evaluate the kind of symbol to use as part of an AAC assessment rather than picking one at random or using one based on our own convenience. There is no empirical evidence that one type of symbol is superior to another for all AAC clients, but there may certainly be differences for a specific individual.Here are some things to think about as you and your team are making these decisions. There are many options in symbol sets and systems, and each has its own strengths and weaknesses. These are each great ways of visually representing language, but here’s something to think about: Does it help or hurt Jonah to have 3 different pictures for the same word? He has Smarty Symbols on his AAC app and a classroom core board with PCS, and is using instructional materials using Symbol Stix. On a typical school day, Jonah is likely to encounter at least three types of pictures for the same words. It isn’t uncommon to see situations like Jonah’s. In terms of AAC symbol options, we are living in plentiful times.
