The most accurate and efficient way to screen for developmental delays

This full revised third edition of the Developmental Profile strengthens and updates an instrument already considered the best of its kind. This new edition adds norm-based standard scores, an expanded age, updated item content, clearer interpretive guidelines, a nationally-representative standardization sample, suggested remediation activities and unlimited computer scoring and interpretation.

Because the DP-3 meets federal criteria for evaluating children with developmental problems, it’s useful in 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. In addition, the DP-3's interview format, and provision of a parent report, satisfy the federal requirement that parents be involved in a child’s assessment.

Through 180 items, the DP-3 provides general development scales, as well as the following scale scores:

  • Physical — large- and small-muscle coordination, strength, stamina, flexibility and sequential motor skills
  • Adaptive Behavior — ability to cope independently with the environment–to eat, dress, work, use modern technology and take care of self and others
  • Social-Emotional interpersonal abilities, social and emotional understanding, functional performance in social situations and manner in which the child relates to friends, relatives and adults
  • Cognitive— intellectual abilities and skills prerequisite to academic achievement
  • Communication — expressive and receptive communication skills, including written, spoken and gestural language

Typically, the DP-3 is administered as an interview, in which a parent of caregiver answers “Yes” or “No” to questions about the child. Within each scale, basals and ceilings are used, so that all 180 items don’t have to be administered. “Start” and “Stop” points ensure that only age-appropriate questions are asked, making the interview focused and efficient. And, because each scale has its own norms, all five scales don’t have to be administered, allowing for flexibility in testing.

The DP-3 offers an alternative administration method, with its new Parent/Caregiver Checklist. It contains the same item content as the Interview Form (although the language has been altered slightly). Written at a sixth-grade reading level, the Checklist can be completed without examiner supervision. It offers a convenient option when a face-to-face interview is not possible, due to time or clinical needs.

IDEA Compliance

Efficient and accurate, the DP-3 is an excellent way to identify developmental delays early in a child’s life. Its norm-based standard scores allow comparison of a children’s functioning with that of peers, to design interventions that meet their particular needs, and monitor progress over time. DP-3 norms are based on a sample of 2,216 typically-developing children, representative of the U.S. population in regard to ethnicity, geography, and socioeconomic status. Score are available as standard scores, percentile ranks, stanines, age equivalents and descriptive ranges. This provides flexibility in using, reporting and explaining test results. For example, standard scores might be used to determine eligibility , or for progress monitoring; age equivalents for parent conferences; ad stanines or percentiles for school records. Unlimited Computer Scoring and Interpretation Provided on an unlimited-use CD, the DP-3 computer program saves time, reduces the chance of error, and gives a wealth of information. It includes the following features:

  • Scoring and Interpretation — calculates all DP-3 scores (standard scores, percentile ranks, stanines and age equivalents) and provides a ready-to-use interpretive analysis.
  • Graphic Representation of Scores — a clear-cut, graphic profile makes it easy to spot advanced, or delayed, development across the five scales and the General Development score.
  • Scale Pattern Analysis and Scale-by-Scale Item Analysis — difficult, or impossible, in hand scoring, are teased out in subtle distinctions in a child’s profile. Scale comparisons reveal statistical significance in the pattern of strengths and weaknesses, while item analysis pinpoints skills not yet mastered (failed items) below the child’s ability level on each scale.
  • Individualized Intervention Activities — for each scale, the program suggests teaching activities that address the child’s specific weaknesses.
  • Clinical and Parent Reports — the CD generates both a thorough clinical report for professional, and an easy-to-understand summary for parents. Compatible with most word processing programs, these reports can b e easily customized.

The DP-3 Kit includes the unlimited-use Scoring and Interpretation CD, a Manual and 25 each of the Interview Forms and the Parent/Caregiver Checklists.
