Developmental Profile – Third Edition (DP-3)

The Developmental Profile – Third Edition (DP-3; Alpern, Boll, & Shearer, 2007) is a norm-referenced developmental screening instrument that uses a structured parent interview to determine the child’s present level of functioning. It can be administered either as an interview or provided as a Parent/Caregiver Checklist when a direct interview is not feasible.

Overview

The DP-3 inventories 180 skills and is designed to assess a child’s development on five scales: Physical, Adaptive Behavior, Social-Emotional, Cognitive, and Communication. A General Development Score may also be obtained based on performance on all five scales. It is particularly useful for children with severe disabilities who may not respond to formal evaluation procedures and measures. With the DP-3 (Third Edition), the expanded age range extends from birth through 12 years, 11 months. Newly standardized data allow conversion of raw scores into standard scores, percentiles, stanine scores, age equivalent scores, and descriptive ranges.
