The DP-3 is designed to assess development in children ages birth through 12 years, 11 months.

Features and benefits

  • Because the DP-3 meets federal criteria for evaluating children with developmental problems, it is useful for determining eligibility for special education, planning IEPs, and implementing periodic screening programs. Its five scales correspond to the five domains specified in IDEA for assessing developmental delays.
  • Includes 180 items, each describing a particular skill; the respondent simply indicates on the Interview Form whether the child has mastered the skill in question.
  • Provides a General Development score as well as five scale scores: Physical, Adaptive Behavior, Social-Emotional, Cognitive, and Communication.
  • Within each scale, basals and ceilings are used, so it is not necessary to administer all 180 items. Plus, each scale has its own norms, enabling you to use them individually.
  • When an interview is not possible, the Parent/Caregiver Checklist can be completed by the child’s parent or caregiver without examiner supervision; it contains the same items as the Interview Form.
  • The DP-3 computer program saves time, reduces the chance of error, and gives you a wealth of information. It provides unlimited scoring and interpretation, graphical representation of scores, scale pattern analysis and scale-by-scale item analysis, individualized intervention activities, and clinician and parent reports.
