Developmental Assessment of Young Children

The DAYC can be used to identify children from birth through 5-11 with possible delays in the areas of cognition, communication, social-emotional development, physical development, and adaptive behavior. The measure includes five subtests that you can administer separately or as a comprehensive battery in about 10 to 20 minutes.

Each of the five domains this test measures reflects an area mandated for assessment and intervention in the Individuals with Disabilities Education Improvement Act 2004 (IDEA 2004).

How to Use the Asssessment
The DAYC format allows you to obtain information about a child’s abilities through observation, interview of caregivers, and direct assessment. The DAYC may also be used in arena assessment so that each discipline can use the evaluation tool independently.

Using the DAYC, clinicians will be able to obtain standard scores, percentile scores, and age equivalents. The test also provides a General Development Quotient (GDQ) if all five subtests are completed, but all subtests can be used independently for each domain.
