Using dynamic assessment with learners who communicate nonsymbolically

Abstract

Many individuals with severe disabilities converse primarily by prelinguistic or nonsymbolic communication, using an idiosyncratic repertoire of gestures, vocalizations, and other behaviors. These learners may or may not be intentional in their communication with others, are difficult to understand, may make requests by engaging in problem behavior, and communicate with few conventions other than those developed in their interactions with partners. Traditional static assessment methods often fail to describe accurately the communication abilities of these learners. In this article, the characteristics of dynamic assessment are reviewed and guidelines to assess the abilities of learners and to explore partner and environment factors are provided. In addition, the pilot outcomes of a process for conducting a dynamic assessment are presented.
