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 report finds that improving school attendance is crucial, especially with the increase in chronic absence. Data on unexcused absences should be used to create a more preventive, problem-solving, and equitable response to poor attendance. Labeling absences as unexcused affects how students and families are treated and can lead to punitive measures that may not improve attendance. Overuse of the unexcused-absence label could undermine efforts to partner with students and families to improve attendance.

Educators face a dilemma of staying up-to-date with evidence-based practices while dealing with superficial ideas. Continuous improvement methods can help in testing new ideas but if seen as add-ons, they may not yield sustained improvement. This brief describes the CORE Districts’ five-driver model that deepens educators’ ownership and sustains improvement over time.

This study uses qualitative case study methods to explore how educators establish system-wide continuous improvement capabilities and coherence for implementation, taking into consideration the local contexts. Educators use two bridging approaches to crafting coherence: weaving and stacking. The study contributes to understanding how leaders create shared meaning and practice in complex and dynamic educational systems. The implications for both research and practice are discussed.

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.

This report examines how continuous improvement is applied to educational accountability in California. It analyzes the experiences of two organizations leading networks to increase postsecondary success, aiming to improve the consistency of initiatives using continuous improvement. Key takeaways for districts, county offices, and support providers are provided.

This article explores the issue of satisficing, which is suboptimal responding on surveys, in the context of a large-scale social-emotional learning survey administered to over 400,000 elementary and secondary students. Despite concerns about its impact on data quality, the study found that satisficing had a more modest effect than expected. The article offers an approach for defining and calculating satisficing for researchers, practitioners, and policymakers to improve the quality of survey data.

At the first anniversary of school closures due to COVID-19, nearly half of the K–12 students in the U.S. were attending schools that were either fully remote or offering hybrid instruction, with more than 70 percent of California students attending schools remotely. For this reason, continued efforts to unpack the effects of COVID-19 on student outcomes are especially important for California students, who may be experiencing larger-than-average effects of continued school closures relative to the nation overall.

The CORE Districts in California conducted a survey to measure K-12 students’ social-emotional well-being during the pandemic. Results indicate that students’ personal and interpersonal well-being rated lower than their learning environments. Interpersonal well-being was most correlated with academic achievement. Home/online learning environment improved, but Grades 5-12 students reported not liking school as much in winter 2020-21. Stakeholders should focus on meeting the pressing needs of each group of students.

This brief is one in a series aimed at providing K–12 education decision makers and advocates with an evidence base to ground discussions about how to best serve students during and following the novel coronavirus pandemic.

The central question of this brief is: How can schools and districts monitor students’ social and emotional well-being across the year?

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 article assesses confusion due to negative wording on social-emotional learning (SEL) assessments using mixture IRT models. Results based on student self-reports show confusion biasing scores, especially in Grades 3-5, and correlational relationships between SEL constructs and reading proficiency and ELL status. Using positively oriented items in future SEL measures is recommended to address these issues.

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.

Self-report surveys are used to track students’ social-emotional development. This large-scale panel survey reveals that self-efficacy, social awareness, and self-management decrease after Grade 6, except for growth mindset. Female students report higher self-management and social awareness but lower self-efficacy than males in middle and high school. Students of color and economically disadvantaged students report lower levels of each construct. Policymakers should consider these trends and use self-reports to target interventions and resources.

California's CORE districts have been collecting data since 2014 on social and emotional learning (SEL) and school climate and culture to improve K-12 schools' holistic approach to student development. Advocates argue that a focus on SEL and school culture will lead to higher academic achievement and better well-being for students. The CORE districts developed survey instruments for SEL competencies and school climate perceptions involving students, staff, and parents. Many states and districts have adopted SEL-specific curricula and disciplinary reforms.

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 paper investigates the effect of student satisficing, the act of providing suboptimal survey responses, on data quality in a large-scale social-emotional learning survey. The study examines the prevalence and impact of satisficing among 409,721 students and finds that its effect on data quality is less significant than expected. The paper offers a practical approach to defining and calculating satisficing, useful for researchers, policymakers, and practitioners working with large-scale datasets.

This paper examines which social-emotional skills are most important for student success and how they vary among student subgroups. It uses longitudinal data from over 200,000 fourth through seventh grade students in California to explore growth mindset gaps across student groups and shows the significant predictive power of growth mindset for academic achievement gains, even when controlling for other social-emotional skills and background characteristics.

This paper uses mixture IRT models to evaluate whether students experience confusion due to negative wording of items on a social-emotional learning assessment. It examines the consequences of confusion on student- and school-level scores and correlations with student-level variables, finding that confusion is present and most prevalent in lower grades, and is related to reading proficiency and ELL status. The study recommends the use of positively oriented items in future SEL measures, and suggests bias corrections based on the studied mixture model to maintain measurement continuity.

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 article discusses the use of standardized tests as the primary tool for assessing school-level growth in student outcomes, despite the emerging importance of social-emotional learning (SEL). It presents results from large-scale surveys of students on SEL constructs, and finds significant differences across schools in SEL growth, with magnitudes of differences similar to those for academic achievement. However, caution is recommended in interpreting measures as causal impacts of schools on SEL, as the goodness of fit of the value-added model was considerably lower for SEL measures.

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.
