The Feifer Assessment of Writing (FAW) is a comprehensive test of writing that was designed to measure three subtypes of written language disorders. Academic achievement tests endeavor to evaluate core neuropsychological and theoretical perspectives that identify students at risk. Written assessments have historically focused more on the ability to write, putting ideas together in a sentence, and being able to do so efficiently. Missing from these evaluations is the impact of working memory and other executive functioning abilities, such as the ability to strategically develop a plan, evaluate, monitor, draft, and revisit the text. This review explores the FAW, and its contribution to the neuropsychological evaluation of writing.
