Since 2015, the Maryland State Department of Education (MSDE) has required child care providers who enroll children receiving a child care scholarship to participate in the state’s quality rating and improvement system, Maryland EXCELS, in order to receive child care scholarship payments. To understand how this policy change affected providers’ participation in Maryland EXCELS and families’ access to high-quality child care, and the implementation of Maryland EXCELS more broadly, the Maryland Child Care Policy Research Partnership (MD CCPRP) surveyed child care providers and families through two online surveys and conducted follow-up interviews and focus groups with a subset of those surveyed from 2021–2022. This brief summarizes key findings from these data collection efforts and provides programmatic and future research recommendations for MSDE leaders’ continued consideration in light of recent policy changes implemented since data collection began.
