This report is the result of a multi-phased process to identify and vet a set of early childhood indicators and emerging themes to support the early learning field. Our research focused on identifying a set of early learning indicators and emerging themes that aim to support the variety of actors in this space by: • Emphasizing a systems view of early childhood, where indicators reflect the various layers that affect young children (such as families, education and care settings, and communities) and actors that influence the range of domains that are part of “whole child” development from birth to age 8 • Addressing the critical and growing importance of issues of equity, as the population of young children in the U.S. reflects increasingly diverse racial and cultural backgrounds • Highlighting the role of indicators to serve as a common language and foster communication and collaboration in a field that has been historically fragmented The resulting indicators and emerging themes reflect a distillation of many existing efforts to define early learning indicators. We began with interviews with 40 early childhood experts and conducted a literature review in early learning and related fields. We then reviewed over 1,100 indicators from 11 existing indicator sets, from which we synthesized and prioritized 48 indicators based on our analysis and expert input. In addition to distilling these indicators, we identified gaps where new themes are emerging and further research is needed to develop additional indicators, particularly in the area of racial and cultural equity.
