California’s Transitional Kindergarten (TK) program provides an additional year of schooling within the K–12 system that aims to prepare children for kindergarten. Launched a decade ago with limited eligibility, the program will be expanded to all four-year-olds by 2025–26. Little is known about TK’s longer-term impact—especially among multilingual students and students with disabilities, who might benefit from early identification. Taking stock of TK’s impact so far can help the state expand it successfully.

This study explores the impact of reclassification on social-emotional learning skills (SEL) of English learners (ELs) in grades 4 to 8. Using a regression discontinuity design, the study found that reclassification improved academic self-efficacy by 0.2 standard deviations for students near the cutoff threshold. The results suggest that reclassification can positively influence the academic beliefs of ELs and the authors provide recommendations for districts to create practices that foster such positive beliefs.

This study explores the impact of county-level immigration arrests on the academic achievement, attendance, and perceptions of school climate and safety for Latinx and Latinx English learner students in California's CORE districts. The research found that there is a negative relationship between immigration arrests and these students' academic performance and school experiences. The study recommends policies and practices that can help schools and districts create safer, more welcoming environments for immigrant-origin students and families in the face of anti-immigrant actions.

Collaborative networks using continuous improvement principles can accelerate and spread learning. This brief highlights the importance of understanding the benefits of collaboration, building a culture of trust and vulnerability, and engaging in true collaborative work, not just "show and tell." These lessons can help network members work together effectively to improve outcomes for students in changing conditions.

Parental engagement is essential to improve academic outcomes for all students, particularly low-income, Black, and Latinx students. Distance learning has intensified the need for parental support, but state policies and tools for engagement are inadequate. Local Educational Agencies can remove barriers to data access and support parent engagement by following three key principles and taking related actions.

This study used data from California CORE Districts to explore whether changes in students' self-reported social-emotional learning (SEL) predicted changes in academic outcomes and attendance. The findings revealed that within-student changes in SEL were positively associated with improvements in English language arts (ELA) and math achievement, as well as attendance, and were consistent across various student subgroups.

The CORE districts studied characteristics, outcomes, and transitions of students with disabilities (SWDs). Specific learning disability was the most common type. Males, African Americans, English learners, and foster youth were overrepresented. Chronic absence was higher for SWDs with multiple disabilities. Most SWDs entered special education in K-4 and exited in grades 8-12. These results help identify who may need targeted support.

This brief examines the consistency of the drop in academic self-efficacy during middle school across various student groups, such as demographics, achievement level, and school of attendance. The study finds that the drop is essentially universal across all groups, despite some showing lower self-efficacy than others. Additionally, schools vary in their students' level of self-efficacy, but do not differ much in this trend. The drop in academic self-efficacy is steeper for female students, resulting in lower self-efficacy for girls than boys throughout middle and high school.

This study uses value-added models to explore whether social-emotional learning (SEL) surveys can measure effective classroom-level supports for SEL. Results show that classrooms differ in their effect on students' growth in self-reported SEL, suggesting that classroom-level effects may be larger than school-level effects. However, the low explanatory power of the SEL models means it's unclear if these are causal effects. The SEL measures also capture growth not measured by academic test scores, indicating that classrooms within schools may impact measurable student growth in SEL.

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.

The increase in students opting out of standardized tests is a threat to accurately measuring student achievement. This brief examines the effects of opting out in the CORE districts and models how it could affect accountability measures. More opt-outs could significantly impact some metrics, but the growth measure is largely unaffected. Metrics tracking achievement by cohort are at risk of bias, even with low levels of opting out. Adjusting for characteristics of students who take the tests could be a solution.

Given the importance of a college degree for both individual and societal economic prosperity, policymakers and educators are focused on strengthening the path to college beyond college entry. In this report, we synthesize the existing literature on four factors key to educational attainment—aspirations and beliefs, academic preparation, knowledge and information, and fortitude and resilience—and the implications of each.

Continuous improvement is a holistic and research-based approach to education grounded in the belief that every system is designed to achieve the results it gets; therefore, change must be systemwide, not piecemeal. California is a national leader in the continuous improvement movement that is spreading throughout local school districts as well as state and county offices of education. At its annual conference in February 2019, PACE convened a panel of California educators working on the cutting edge of continuous improvement. In this brief, they share their stories and lessons learned.

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.

Continuous improvement in education involves engaging stakeholders in problem-solving to discover, implement, and spread evidence-based changes that work locally to improve student success. California sees it as central to enduring education transformation. It requires an initial significant investment in time and money to make it a reality, but can improve education quality. However, California's data systems are inadequate for helping districts monitor progress, and more training and coaching are needed to build expertise for statewide implementation.

The use of social-emotional learning (SEL) and school culture/climate (CC) measures is a promising way to understand school performance. SEL and CC measures are reliable, distinguish between schools, and relate to academic and non-academic measures. They can identify areas for improvement within schools, such as subgroup gaps. Incorporating these measures into higher stakes accountability systems requires further research.

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.

This report examines the Every Student Succeeds Act (ESSA) and how schools can be identified for support and improvement using a multiple measures framework. The authors find that different academic indicators measure different aspects of school performance and suggest that states should be allowed to use multiple measures instead of a summative rating. They also find that non-academic indicators are not given enough weight and suggest a clarification in federal policy.

This policy brief analyzes the implications of using various subgroup sizes for school-level reporting under the ESSA. Data from the CORE Districts shows that a subgroup size of 20+ offers clear advantages in representing historically underserved student populations. The authors also produced a supplementary report comparing subgroup sizes of 20+ and 30+ in response to new ESSA regulations.

To support policymaker discussions on including chronic absenteeism data in California's accountability system, PACE analyzed the CORE Districts' student chronic absenteeism data. It is feasible to include chronic absence as a measurement using the state's approach for rating school achievement based on outcome and improvement or by simply looking at performance in a given school year.

This brief provides an overview of California's existing network of preschool centers and the potential impact of Proposition 82, which would provide funding for half-day preschool programs for 70% of the state's four-year-olds. PACE, an independent research center, aims to clarify evidence informing education policy options. A 2005 PACE review focused on enrollment patterns and policy options for improving access and quality of local preschools.
