In the Pennsylvania General Assembly, the bipartisan and bicameral Early Childhood Education Caucus has more than 100 members, and since its launch in 2014, the Pre-K for PA campaign has reported on connections between state early childhood policies and the criminal justice system, K-12 education, and workforce quality. The campaign has worked to increase public funding to serve more children and focus on strengthening the early childhood education system. The campaign developed this report to describe the effective, but sometimes opaque system Pennsylvania has created to provide high-quality public pre-k. (author abstract)
