Public PreK programs are an increasingly popular policy tool to equalize early learning opportunities. Programs can be universally available or targeted to support children's readiness. At the intersection of early childhood and K-12 education, their hybrid status can be difficult for families to negotiate. Based on interviews completed in 2018, we describe how parents in a universal PreK program decided whether and where their child would attend PreK, comparing parents who chose school sites with those who did not. The part-time nature of the program was a barrier to many families, prompting us to ask whether a program is authentically universal if it is not accessible to all.
