Early care and education providers are subject to monitoring by multiple agencies and organizations. In this brief, we first provide an overview of monitoring and the major early care and education monitoring systems. We then offer possible goals for a coordinated monitoring system and describe some approaches to addressing those goals. We also describe 11 dimensions that are important to consider in planning monitoring coordination efforts. We highlight the efforts of two states, Ohio and Rhode Island, that are working to coordinate their early care and education systems. The appendix provides an overview of eight major early care and education monitoring systems. This publication has a companion tool, Mapping the Early Care and Education Monitoring Landscape (Maxwell, Sosinsky, & Tout, 2016), to help leaders better understand the current monitoring systems and plan future coordination efforts.
