PURPOSE
The normative group of a norm-referenced test is intended to provide a basis for interpreting test scores. However, the composition of the normative group may facilitate or impede different types of diagnostic interpretations. This article considers who should be included in a normative sample and how this decision must be made relative to the purpose for which a test is intended.
METHOD
The way in which the composition of the normative sample affects classification accuracy is…

Children with SLI are unlikely to score low on these commonly used receptive vocabulary tests, despite known deficits of children with SLI in the area of vocabulary acquisition, and the misperception that newer test versions are superior to older in identifying presence or absence of language impairment is highlighted.
