Abstract
The reliability and concurrent validity of the Minnesota Child Development Inventory (MCDI) as a measure of developmental functioning with handicapped children was investigated with a sample of 72 moderately to severely handicapped children, aged 38 to 77 months. Although the MCDI is not as strong psychometrically as other standardized measures of developmental functioning typically used with this population, results were moderately encouraging, given the ease and economy with which MCDI can be administered. Suggestions for further research and validation are made.
