The positive relation between child care quality and virtually every facet of children’s development that has been studied is one of the most consistent findings in developmental science.

Quality in early childhood programs matters! This is one of the key conclusions from three decades or more of research on child care and child development. In fact, studies from a number of countries show that the importance of quality in child care cannot be overstated. High-quality early childhood programs such as child care provide children with many benefits. They can be ineffective if the quality is poor.
