At what age is the DAYC-2 developmental assessment used?
The DAYC-2 (Developmental Assessment of Young Children, 2nd edition) is used for children from birth to 5 years 11 months. It is a clinician-administered tool that looks at five areas of early development — communication, cognition, physical, social-emotional and adaptive behaviour — making it useful from the newborn weeks through the preschool years.
Read the answer AnswerWhat is the DAYC-2 and what does it assess?
The Developmental Assessment of Young Children, 2nd edition (DAYC-2) is a structured developmental assessment for children from birth to about 5 years 11 months. Administered by a trained professional through observation, play and parent interview, it maps five areas of growth: communication, cognition, physical (motor) development, social-emotional development and adaptive (self-care) behaviour. It is a measurement and mapping tool, not a diagnosis, used to build a whole-child profile and guide early support.

How the DAYC-2 compares with the AbilityScore assessment
The DAYC-2 is a standardised, norm-referenced tool comparing a child against age expectations across five domains, used mainly for screening and eligibility. The AbilityScore is Pinnacle's clinician-administered structured assessment that maps a child against their own baseline to drive a personalised, evolving therapy plan. They are complementary rather than competing, and any diagnosis is formed only by a qualified Pinnacle clinician.
Read the answer AnswerShould my child have a DAYC-2 assessment, and what does it involve?
The DAYC-2 is a gentle, clinician-administered assessment for children from birth to about 5 years 11 months, looking at communication, cognition, motor skills, social-emotional development, and everyday adaptive skills. It uses observation, play-based activities, and a parent interview to map your child's strengths and areas needing support. Whether it suits your child is best decided with a clinician — it is one helpful tool, never a label.

The DAYC-2 is a norm-referenced tool for children from birth to ~5;11, profiling cognition, communication, social-emotional, physical and adaptive development. Strengths include breadth and flexible administration via observation, interview and direct testing; limits include reliance on examiner and informant judgement, age-extreme ceiling/floor effects, and that it characterises rather than confirms diagnosis. Best used as one input within a wider clinician-led assessment.
