Goal: Use research to refine policies and practices in order to facilitate greater continuity and stability in subsidized child care, thereby making services more family-friendly and supportive of positive child outcomes. Objectives: - Describe longitudinal patterns in the continuity of subsidy spells and identify differences in these patterns by child, family, and community characteristics - Examine the association between use of high quality care and continuity in subsidized care arrangements - Determine whether Maryland's shift to a private, centralized subsidy case management system is associated with changes in the length of (family) eligibility periods as well as voucher length.
