Parent report measures have made a significant contribution to the measurement of early language development. The MacArthur Communicative Development Inventory-Level III (CDI-III) is such a measure intended for children 30-43 months. At present, norming and validation data are just emerging and its ability to categorize groups of children of different language status is unknown. Thus, the following investigation sought to determine whether the CDI-III could correctly discriminate between children with and without language impairments. Participants were 69 English-speaking children between 30-45 months of age, including 15% who were known to have a language impairment. Discriminant Analysis revealed that 92.8% of the participants were correctly classified based on CDI-III total score. 78% of children with language impairment were correctly identified. Our data suggest that using the CDI-III is a valid initial, but not sole, step in the process of identifying young children with language impairments.
