Purpose: Quickly identify developmental strengths and weaknesses in five key areas and offer suggested activities for remediation Age: Birth – 21.11 Time: 20–40 minutes
The Developmental Profile™ 4 (DP-4) is a comprehensive assessment instrument with a simple yes-or-no response format that includes 190 test items, each describing a particular skill. The respondent indicates whether or not the child has mastered the skill in question.
Within each of the five scales on the interview form, start and stop rules are used, so you don’t have to administer all items. Each scale has its own norms, so you don’t have to use all five scales if you’re interested in just one area of development. Additionally, there’s an intervention activity for every item.
New Features
Upgraded with a broader age range
Updated items reflect changes in society, technology, and culture
New growth scores monitor progress over time
Updated norms based on a new, nationally representative standardisation sample
Two new forms (Teacher Checklist and Clinician Rating) strengthen overall evaluation
Updated items to accommodate children who are deaf/hard of hearing
Four forms offer flexible administration – three forms (Parent/Caregiver Interview, Parent/Caregiver Checklist, and Teacher Checklist) provide standard scores and growth scores.
The Clinician Rating form provides growth scores for monitoring progress.
The DP-4 Kit includes:
DP-4 Manual
25 Parent/Caregiver Interview Forms
