The Quick Answer
The Written Expression composite on the WIAT-4 is a single score that summarizes how well a person expresses ideas in writing. It pulls together the mechanics of writing, such as spelling and forming letters, and the composition of writing, such as building sentences and organizing ideas. In short, it reflects how well a person gets thoughts onto the page in a way a reader can follow. It is one of the core academic areas the WIAT-4 measures.
