As a result of the heightened public and political attention and the movement toward standards and accountability, performance measurement has emerged as an important concern in the early childhood care and education field. At the request of the Department of Health and Human Services' Administration for Children and Families, the Board on Children, Youth, and Families convened two workshops to learn from existing efforts to develop performance measures for early childhood care and education, to consider what would be involved in developing and implementing an effective performance measurement system for this field, and to delineate some critical next steps for moving such an effort forward.
