This report commemorates the fifth anniversary of the Getting Down to Facts project, which sought to provide a thorough and reliable analysis of the critical challenges facing California’s education system as the necessary basis for an informed discussion of policy changes aimed at improving the performance of California schools and students. The report focuses on the four key issues that received emphasis in the Getting Down to Facts studies: governance, finance, personnel, and data systems.

This report examines the effects of preschool or childcare exposure on cognitive and social development before kindergarten, focusing on intensity and duration of attendance, and how this varies across different income and ethnic groups. The authors utilize data from a nationally representative sample of young children with rich family background information. Findings are important for debates over extending free preschool and which groups of children would most benefit.
