Product Details

Each of the five DAYC-2 domains — Cognition, Communication, Social-Emotional Development, Physical Development, and Adaptive Behavior — reflects an area mandated for assessment and intervention for young children in IDEA.


  • Obtain information about a child’s abilities through observation, interview of caregivers, and direct assessment.
  • Test only the domains of interest or test all five domains when a measure of general development is desired. 


DAYC-2 was normed on a national sample of 1,832 children. Standard scores, percentile ranks, and age equivalents are provided for each domain, and for overall general development if all five domains are tested.

  • Subdomain scores provided for receptive language and expressive language within the Communication Domain, and for gross motor and fine motor within the Physical Development Domain.
  • Examiners may select the subdomain or domain scores that interest them.
  • Numerous validity studies, including studies of the test’s sensitivity and specificity, are provided.
  • Simplified ceiling rule and reworded items for clarity.
  • All new normative data collected in 2009 - 2011
