Child Measurement Programme for Wales


The Child Measurement Programme for Wales measures the height and weight of children in Reception class.

We want to learn how children in Wales are growing so that NHS Wales can better plan and deliver health services.

Public Health Wales is responsible for the coordination of the Child Measurement Programme and every health board across Wales is taking part in the programme.
