Maryland and Minnesota are two states that have been leading innovations across early care and education (ECE) policy and simultaneously investing in research and data infrastructure to ensure that their strategies are informed by evaluation and new evidence in the field. The Maryland-Minnesota Child Care Research Partnership received a grant in 2010 from the federal Office of Planning, Research and Evaluation to examine critical issues in early care and education and use research findings to inform policy. The Partnership plans were developed in collaboration with an interdisciplinary team of researchers at Child Trends, the University of Minnesota, RESI at Towson University and Wilder Research, and state partners at the Minnesota Department of Human Services and the Maryland State Department of Education. The purpose of the Maryland-Minnesota Child Care Research Partnership is to collect information about low-income families' experiences with early care and education for their young children that can be used to improve state policies and practices. Child care subsidies that provide financial assistance to eligible low-income families are a focal topic of the research conducted by the Partnership and a subject of four new research briefs: (1) Stability of Subsidy Participation and Continuity of Care in the Child Care Assistance Program in Minnesota; (2) Continuity of Child Care Subsidy Receipt: Why Definitions of Spells and Gaps Matter; (3) Implementation of 12-Month Child Care Subsidy Eligibility Redetermination: A Case Study from Maryland; and (4) Changes in Child Care Arrangements of Young Children in Maryland. Each brief also includes a summary.
