California’s Kindergarten Readiness Act of 2010 established transitional kindergarten (TK), the first year of a two-year kindergarten program for students affected by the change in the birthdate cutoff for entry into kindergarten from December 2 to September 1. This final report from the program’s evaluation focuses on results from a five-year study. The study used a rigorous regression discontinuity design to examine whether TK, as a new approach to prekindergarten education for age-eligible students, leads to positive outcomes, for which students, and under what conditions.

Quality rating and improvement systems (QRISs) constitute an ambitious policy approach to improving early care and education practices and child outcomes. A QRIS is a uniform set of ratings, graduated by level of quality, used to assess and improve early learning and care programs. The purpose of this study, conducted by AIR and the RAND Corporation, is to support the state of California and its counties in their efforts to build robust, evidence-based quality improvement systems.
