Research on programs for any population of children should examine such program variations as age groupings, adult-child ratios, curricula, class size, and program duration. These questions can best be answered through longitudinal studies employing random assignment. In developing and assessing curricula, new research must also continue to consider the interplay between an individual child’s characteristics, the immediate contexts of the home and classroom, and the larger contexts of the formal school environment.

Recommendation 18: A broad program of research and development should be undertaken to advance the state of the art of assessment in three areas: (1) classroom-based assessment to support learning (including studies of the impact of methods of instructional assessment on pedagogical technique and children’s learning); (2) assessment for diagnostic purposes; and (3) assessment of program quality for accountability and other reasons of public policy.

Research on Ways to Create Universal High Quality

Recommendation 19: Research to fully develop and evaluate alternatives for organizing, regulating, supporting, and financing early childhood programs should be conducted to provide an empirical base for the decisions being made.

The current early childhood system is fragmented, lacks uniform standards, and provides uneven access to all children. Numerous policy choices have been proposed. This research would inform public policy decision making.


At a time when the importance of education to individual fulfillment and economic success has focused attention on the need to better prepare children for academic achievement, the research literature suggests ways to make gains toward that end. Parents are relying on child care and preschool programs in ever larger numbers. We know that the quality of the programs in which they leave their children matters. If there is a single critical
