Researchers at Chapin Hall at the University of Chicago (Chapin Hall) and the University of Chicago Consortium on School Research (UChicago Consortium) studied the first full-year implementation of PKTP in 2016-17. This report provides an overview of PKTP's approach as a transitions program; describes implementation fidelity, successes, and challenges; and characterizes teacher and family reports about their experiences with this effort to create coherence across the schools and centers in Altgeld-Riverdale. Studying this model offered an opportunity to add to a new and growing knowledge base about implementation efforts to improve kindergarten transition experiences. (author abstract)
