A review of the literature on educational outcomes for children of early childhood education can provide relevant information for policymakers. Research suggests that the quality of programs offered in early childhood centers affects the extent to which children experience education. On the basis of the studies, the main characteristics of low quality centers are: (1) inappropriate caregiver-child ratios; (2) inadequate staff training; (3) large group size; (4) high staff turnover; (5) inexperienced staff; (6) inappropriate programs; (7) low levels of interaction; (8) limited parental involvement; (9) low maintenance of indigenous cultures; and (10) an inadequate physical environment. Insufficient provision of early childhood services adversely affects all children, but affects most strongly those children who are at risk. Recent research also highlights the importance of funding levels in the maintenance of quality programs. In New Zealand, the quality of early childhood centers and the provision of early childhood education compares favorably with the quality and provision found in the United States. Research with children in New Zealand childcare centers supports the importance of high staff-child ratios, staff training, and ongoing inservice training. (Contains 86 references.) (SW)
