Newly released data from the National Survey of Early Care and Education provide a unique opportunity to understand Head Start and Public Pre-K offerings within the context of all center-based ECE to children age five and under. These two prominent initiatives involve almost 40 percent of all ECE centers nationally. Most centers receiving any Head Start or Public Pre-K funding are also serving young children through other ECE services such as parent-funded preschool. In fact, 25 percent of centers with Head Start (but no Public Pre-K) funding and 45 percent of centers with Public Pre-K (but no Head Start) funding are also supported with private funds. Fewer than one in five centers with Head Start or Public Pre-K funding are operated by a public school district. The NSECE data indicate that ECE centers nationally are a diverse group in terms of size, auspice, mix of public/private funding, and other characteristics; the same can be said for centers receiving any Head Start or Public Pre-K funds.
