This document discusses aided language stimulation (ALS), which is a communication strategy where a partner models language use by combining verbal input with selecting vocabulary on an augmentative communication system. ALS teaches symbol meaning and language in the same way that verbal children learn. Research shows that ALS has been an effective practice since 1988 for all individuals using augmentative communication. The document provides guidelines for implementing ALS, such as gaining attention, modeling core language, and using recasting to add or correct information.
