The primary purpose of the 2016-2017 NC Pre-Kindergarten (NC Pre-K) Evaluation study was to examine variability in enrollment practices within the statewide Pre-K Program. Four major categories of enrollment practices were examined: recruitment, application, placement, and waitlist. The study involved all 91 local NC Pre-K Program contracts, with data gathered through both surveys and phone interviews. The results provided information about local variations in implementation of the NC Pre-K Program and how these variations impacted who was served and not served by the program; how placement decisions were made; who was on the waitlist (i.e., those who applied to the NC Pre-K Program but were not selected); and the extent of collaboration and coordination of NC Pre-K with other programs and agencies. Second, these data also were used to inform the feasibility and design of the subsequent year's evaluation utilizing a randomized controlled trial (RCT) design. (author abstract)
