Features

The PDMS 3 has several enhancements from the previous edition:

  • The subtests of the PDMS-3 were renamed to reflect a better understanding of the skills required by the items.
  • The addition of the supplemental Physical Fitness subtest reflects the current literature’s interest in overweight, obesity, and fitness testing of preschool children.
  • Examiner Record Booklets now contain complete administration and scoring instructions, allowing administration of the test without using the Examiner’s Manual.
  • The kit now includes a Scoring Transparency containing images of a protractor and ruler to aid examiners in scoring.
  • The revised Illustrated Guide to Item Administration includes many replaced and updated illustrations.
  • The Motor Activities Program was revised to be more user friendly. It contains units organized developmentally by skill area to facilitate the child's development in areas assessed as requiring intervention.
  • The manipulative kit includes most of the manipulatives needed for testing to better ensure the standardized administration of items.
  • Updated Peabody Motor Development Chart
  • Norms are based on a sample of 1,452 children who were tested from Spring of 2016 through Spring of 2021.
  • Standardized scores and corresponding narratives are obtained via the PDMS-3 Online Scoring and Report System.

The majority of the PDMS-3 normative sample was collected prior to the pandemic, but the raw score means of the data collected during the pandemic were compared to the raw score means of the data collected prior to the pandemic and found to be very similar.
