With limited federal requirements for block grants, states have developed very different welfare policies, often with onerous recertification or reporting requirements, creating barriers to continuous program enrollment. Examined through the framework of Administrative Burden, our study examines how changes to burdensome policies in states’ Child Care Development Fund (CCDF) programs affect the length of children’s continuous enrollment in child care through the CCDF program, known as subsidy “spells.” We exploit state-level changes in three key policies during a 10-year period (2004–13) that capture administrative burden: (1) length of eligibility redetermination; (2) reporting requirements for income changes; and (3) grace period for care before termination.
