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 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.

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 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.

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.

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.

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.

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.

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.

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.

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.
