The DP-3 is a powerful, quick, and cost-effective developmental test for children.

Features and benefits

  • Quickly identifies strengths and weaknesses. 
  • Helps plan interventions with item-by-item teaching activities. 
  • Meets the federal criteria for evaluating children with developmental problems.
  • Helps determine eligibility for special education and assists with writing IEP goals.
  • Determines specific areas that need further assessment. 
  • Monitors progress over time. 
  • Use to investigate puzzling behavior, respond to parental concerns, or follow up on teacher observations.

Test structure

  • The DP-3 measures development across five scales:
    • Physical: Large and small muscle coordination, strength, stamina, flexibility, and sequential motor skills.
    • Adaptive behavior: the ability to cope independently with the environment—to eat, dress, work, use current technology, and take care of self and others.
    • Social–Emotional: interpersonal skills, social–emotional understanding, functioning in social situations, and manner in which the child relates to peers and adults.
    • Cognitive: intellectual abilities and skills prerequisite to academic achievement.
    • Communication: expressive and receptive communication skills, including written, spoken, and gestural language.
  • Includes 180 items, each describing a particular skill, and uses a simple yes-or-no format.
  • 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.

Technical information

  • Uses norm-based standard scores, percentiles, stanines, age equivalents, and descriptive ranges.
  • Standardized on a nationally representative standardization of 2,216 typically developing children.
  • Demonstrates strong reliability and validity.
