California's investment in Universal Transitional Kindergarten (UTK) reflects a commitment to providing access to UTK for all 4-year-olds in public schools by the 2025-2026 academic year. However, the implementation of transitional kindergarten (TK) presents challenges for districts in aligning this new grade coherently with existing grade levels…

In 2021, California committed to making transitional kindergarten (TK)--a school-based preschool program initially designed for older 4-year-olds--available for all 4-year-olds by 2025-26. As TK becomes universal, California will need to greatly expand the early learning workforce. This brief provides estimates of how many TK teachers California…

To provide a landscape of mathematics activities children experience in U.S. preschool and kindergarten classrooms, we observed time children spent in mathematics activities (and -- as a contrast -- literacy) in 101 geographically diverse early childhood classrooms in seven U.S. states. We also observed what mathematics content, grouping…

In an effort to improve learning for young children and respond to preschool fade out, some districts are working on "PreK-3" initiatives to create better connected learning pathways for children. In these pathways, primary grades continue to build on what children learn in preschool; they also present potential implementation challenges…

School discipline policies are broadly intended to foster a high-quality learning environment by maintaining safety in the classroom; however, far too often, schools adopt measures that harm a student's social, emotional, academic, and in some cases, physical health and well-being. To create physically safe and emotionally supportive environments…

California is on the cusp of implementing universal preschool--a step that could help level the playing eld for young children. Over the next few years, all four-year-olds will become eligible for Transitional Kindergarten (TK), which has been part of the state's early learning programs since 2012. In the report, "Setting the Stage for…

This transnational comparative study between Costa Rica and the United States provides an in-depth understanding of the similarities and differences of the early literacy practices of educators in the Pre-Kindergarten to Kindergarten classroom settings. Drawing upon Costa Rica's curricular approach to Early Childhood Education, based upon the…

A socioeconomic status (SES)-related achievement gap in mathematics emerges prior to school entry, and increases in elementary school. This gap makes implementation of demanding mathematics standards (e.g., the Common Core State Standards) an ongoing challenge. Early educational intervention is a strategy for addressing this challenge. A…

In 2021, California made major new investments to advance its commitment to early childhood education through universal preschool. One important investment was extending state funding for transitional kindergarten (TK), previously just for older 4-year-olds, to all 4-year-olds by 2025-26. To ensure the quality of new preschool investments,…

High-quality early learning experiences (i.e., developmentally appropriate, play-based instruction with clear learning goals) have positive long-term effects on student outcomes. As California rolls out Universal Transitional Kindergarten (UTK), district leaders focused on meeting state requirements for hiring qualified staff and finding…

A socioeconomic status- (SES-) related achievement gap in mathematics emerges prior to school entry, and increases as children move through elementary school. This gap makes implementation of demanding mathematics standards (e.g., the Common Core State Standards) an ongoing challenge. Early educational intervention is a strategy for addressing…

In 2021, California made historic investments in early learning to expand transitional kindergarten (TK) to serve all of California's 4-year-olds. Transitional kindergarten began in California in 2012 as a free public school program for 4-year-olds who were not yet eligible for kindergarten (a non-compulsory grade). Yet by 2019, just 28 percent of…

Parent-teacher relationship (PTR) quality is linked to child and family-school functioning and may be especially important in the school adjustment of autistic children. However, measurement of PTR quality has been limited by inconsistency in the use of measures, a paucity of two-informant measurement, and limited psychometric consideration. We…
