Research and expert perspectives agree that one of the key elements that determines the quality of an early childhood education and care program is the number of adults to children - the ratio. However, it is also clear that the adult: child ratio is not the sole quality-determining element. Other important elements, especially training and qualifications, interact with ratio to form the structural and pedagogical base for quality in an ECEC program.
