The Developmental Profile (DP-4)
What It Measures
The Developmental Profile 4 (DP-4) is a questionnaire completed by someone who knows a child well, describing what that child can already do. It covers five areas of development: physical, adaptive behavior, social-emotional, cognitive, and communication — the same five domains IDEA specifies for assessing developmental delay.
Items use a plain yes-or-no format, each describing one specific skill, which is what keeps the assessment quick despite covering birth through age 21. Standard scores compare a child with peers their own age. Growth scores are the more useful output for children functioning at a very low level. Every item comes with a matched intervention activity.

Learn More: Four forms exist, the Parent/Caregiver Interview, Parent/Caregiver Checklist, and Teacher Checklist all yield both standard and growth scores. The Clinician Rating Form yields growth scores only. Each scale has its own start and stop rules, and all five scales are not required if only one area is of interest.
