DAYC-2 Developmental Assessment of Young Children | Second Edition

Developmental Assessment of Young Children | Second Edition – Comprehensive Early Childhood Developmental Assessment Tool

Evaluate Key Developmental Domains in Children from Birth to 5 Years

 

The Developmental Assessment of Young Children – Second Edition (DAYC-2) is a widely trusted, standardized tool designed to identify developmental delays in children from birth through 5 years of age.

The DAYC-2 assesses five essential developmental domains that align with the IDEA-mandated early childhood areas for evaluation and intervention:

1. Cognition

2. Communication (including Receptive & Expressive subdomains)

3. Social-Emotional Development

4. Physical Development (including Gross & Fine Motor subdomains)

5. Adaptive Behavior

This flexible assessment can be administered through direct testing, caregiver interviews, or natural observation, providing a comprehensive picture of a child’s strengths and developmental needs.
