This brief is part of an ongoing study that is tracking implementation of the Boston Universal Prekindergarten (UPK) expansion, including effects of the COVID-19 crisis on UPK community-based centers. We use administrative and interview data to provide a descriptive snapshot of the impacts of the COVID-19 pandemic on UPK centers so far, focusing on three areas: teacher and administrator turnover; child enrollment; and changes in practices that centers are implementing to increase safety. Unlike many programs across the country, UPK centers have continued to receive full funding for UPK slots and for child-care subsidy slots throughout the crisis. As such, the effects we describe here likely represent a “best case” scenario for centers operating in urban areas serving mostly children from families with low incomes. (author abstract)
