Until the 1980s, preschools in most countries were largely focussed on providing simple child minding. But as economies shift towards more knowledge-based activities, awareness about child development—the need to improve their social awareness, confidence and group interaction skills, and to prepare them for starting primary education—continues to grow. Nevertheless, policymakers still give most attention to the tertiary, secondary and primary levels of education, in descending order of importance, with the least focus given to the early years of child development.
