This case study explores the Garden Grove Unified School District's culture of improvement through four key structures and processes, including consistent goals, data-driven reform, vertical and horizontal structures, and prioritization of people. The district's culture prioritizes student outcomes, commitment, and high-quality teaching. Lessons from GGUSD are broadly applicable to other California districts seeking to foster a culture of improvement.

The CORE-PACE Research Partnership's report on Long Beach Unified School District highlights lessons learned from their continuous improvement approach to improving classroom instruction. This report describes four key practices that have led to improvements in organizational function, including shared clarity of purpose, structures for shared learning, differentiated support for instructional leaders, and deepening understanding of implementation. LBUSD's efforts offer valuable insights for other systems and leaders seeking to support continuous improvement.

A case study of Ayer Elementary School in Fresno, California, reveals leadership practices that foster continuous improvement in education. The report identifies three lessons for supporting improvement in other schools: access to district resources, a culture of continuous improvement, and teacher agency. The study highlights the importance of leadership skills in promoting a culture of risk-taking, teacher agency, and collective efficacy to improve student outcomes in California schools.

This report examines how California's education sector is embracing continuous improvement over standards-based reform. The study presents six lessons learned from PACE and CORE Districts' collaboration on the topic, including the complexity of embedding continuous improvement processes into school norms and the need for deliberate steps to build a culture conducive to continuous improvement. The report provides implications for broader continuous work in California and beyond, with three case studies providing more detail on exemplary practices in two districts and one school.

This report examines the stability of school effects on social-emotional learning (SEL) over two years in California's CORE districts. The correlations among school effects in the same grades across different years are positive but lower than those for math and ELA. While these effects measure real contributions to SEL, their low stability draws into question whether including them in school performance frameworks and systems would be beneficial.

California’s shift towards continuous improvement in education makes understanding how districts and schools can learn to improve a more pressing question than ever. The CORE Improvement Community (CIC), a network of California school districts engaged in learning about improvement together, is an important testing ground to learn about what this work entails.

Effective data use is crucial for continuous improvement, but there is confusion about how it differs from data use for other purposes. This report explains what data are most useful for continuous improvement and presents a case study of how the CORE data collaborative uses a multiple-measures approach to support decision-making.

This report discusses the validity and reliability of CORE Districts’ social-emotional learning (SEL) student-report surveys. Through a pragmatic approach, the report answers four guiding questions that explain different facets of validity for school leaders. The aim is to provide guidance around the use of SEL surveys within and outside of the CORE districts to facilitate decision-making for educational leaders.

This study examines the properties of California's CORE Districts' SEL survey, which measures social-emotional learning in students. The survey was given to over 400,000 students in grades 3-12. The study uses both classical test theory and item response theory frameworks to analyze the data and make recommendations for modeling and scaling SEL survey data. Policy implications are discussed for educators, administrators, policy makers, and other stakeholders.

This study explores ten "outlier schools" in California's CORE districts that have strong social-emotional learning outcomes. The brief and infographic summarize the various practices found in these schools and the common implementation challenges faced. The findings offer lessons that can help other schools and districts implement social-emotional learning at scale.

States and school districts across the U.S. are seeking to expand their definition of student success to include social-emotional learning. The CORE Districts, a collaborative of California districts that has developed a system of school accountability and continuous improvement that includes measures of social-emotional skills based on student self-reports, exemplify this trend. In this case study, we provide an overview of CORE's School Quality Improvement System, which was implemented in the 2015–16 school year across six districts serving roughly one million students.

California's Local Control Funding Formula (LCFF) aims to improve educational equity by providing additional funds to districts with disadvantaged students. Districts are required to engage with their communities and develop Local Control Accountability Plans (LCAPs) to identify priorities and allocate funds. However, there are concerns about the quality of LCAPs, lack of stakeholder involvement, and limited transparency. To improve the effectiveness of LCFF, districts must ensure meaningful stakeholder engagement and use data to guide decision-making.

California's Local Control Funding Formula (LCFF) requires districts to report student performance measures and use state and local data to monitor progress towards preparing students for college, career, and citizenship. Fresno Unified School District (FUSD) utilized principles of Improvement Science and a data dashboard to increase college access for students, in partnership with the University of California, Merced.

The Local Control and Accountability Plan (LCAP) in California and the federal Every Student Succeeds Act (ESSA) encourage local control in school accountability. The CORE waiver districts have implemented an innovative measurement system and supports for school and district improvement, providing an opportunity to learn from the enactment of a system supported by accountability policy in this new era. This report examines the early implementation and effects of the CORE reform and seeks to inform the ongoing efforts within CORE and future accountability policy in other states and districts.

California and the US are undergoing a cultural shift in school accountability policies towards locally-determined measures of school performance. Lessons can be learned from the CORE districts, which developed an innovative accountability system, emphasizing support over sanctions, and utilizing multiple measures of school quality. The CORE districts' measurement system and collaboration hold promise for improving local systems, but efforts to build capacity remain a work in progress.
