In a recent study of Head Start's impact on early childhood education, a meta-analysis reviewed 28 studies from 1965 to 2007. Head Start yielded a 0.27 effect size, indicating modest improvement in children's short-term cognitive outcomes, aligning with general early childhood education programs. Yet, its effects were smaller compared to more intensive programs like Perry Preschool, but within the range of wider ECE averages. Research design significantly influenced these outcomes, particularly the nature of the control group. Studies with an "active" control group, exposed to other forms of ECE, showed smaller effects than those with a "passive" group, receiving no alternative ECE. As ECE attendance rises, communities with multiple ECE options could produce smaller Head Start effects. This does not question Head Start's efficacy but highlights other effective ECE alternatives, skewing comparative evaluations. Skills closely tied to ECE curricula, like early reading and math, responded better to Head Start than broader cognitive skills, suggesting tempered expectations for effects on measures like vocabulary or IQ. Finally, the study emphasizes considering measurement quality when interpreting program evaluation outcomes.

A new study explores the impact of full-day kindergarten on English learner (EL) students in California, a group previously overlooked in research on extended kindergarten programs. While overall findings showed no significant difference in performance between EL full-day and half-day students in first or second grades, nuanced benefits surfaced within specific subgroups. EL students in full-day programs were 5.2% less likely to face retention in early grades, indicating potential help for at-risk students. Moreover, EL students with stronger English skills upon kindergarten entry exhibited advantages: they were more likely to progress to fluent-English proficiency by second grade, demonstrated higher reading skills, and slightly improved English fluency. Interestingly, students from lower-performing schools experienced the most substantial benefits from full-day kindergarten. Despite no broad performance differences, targeted advantages for specific EL subgroups emphasize the nuanced impact of extended kindergarten hours. Schools considering adopting full-day programs should weigh these specific benefits against implementation costs for individual districts.

For nearly three decades, PACE has facilitated discussions on California's education policies by integrating academic research into key policy challenges. Traditionally, this involved publishing policy briefs, organizing seminars, and producing the annual 'Conditions of Education in California' report, offering comprehensive data and analysis on the state's education system. The launch of "Conditions of Education in California" as a blog marks a shift to engage a wider audience and enable ongoing updates. This platform, authored by PACE-affiliated researchers across California, aims to share new data, compelling research findings, and insights on current legislation and policies. The objective remains fostering informed discussions on education policy challenges in California, now extending the conversation to policymakers, educators, and citizens. This inclusive dialogue is crucial to drive the necessary policy understanding and momentum for improving the state's education system.

"Getting Down to Facts" is a new research initiative commissioned by Governor Schwarzenegger's Committee on Education Excellence, state Democratic leaders, and Superintendent Jack O'Connell. Led by Susanna Loeb, a Stanford Graduate School of Education Professor and PACE codirector, this project seeks to explore California's school finance and governance systems. Its objective is to provide comprehensive insights essential for assessing the effectiveness of potential reforms. The initiative addresses three key questions: the current state of school finance and governance, optimizing existing resources for improved student outcomes, and evaluating the need for additional resources to meet educational goals. The studies from this project are expected to be available by January 2007.
