The DAYC-2 (Developmental Assessment of Young Children, Second Edition) is a standardized assessment tool used to evaluate developmental skills in children from birth to 5 years old. It assesses cognitive, communication, social-emotional, physical, and adaptive behavior domains to identify developmental delays early. At OrbRom Center in Phnom Penh, Cambodia, we utilize the DAYC-2 as part of our comprehensive evaluation process to design effective, individualized therapy programs.
