Evidence shows that children's early years are a crucial time for their development. Well-designed early childhood education (ECE) experiences can foster meaningful gains in school readiness, as well as long-term benefits such as lower rates of special education placement and higher graduation rates. The quality of early education is highly…

Early childhood researchers from across the U.S. came together to form the Early Learning Network (ELN) in 2016 with the mission to identify policies and practices that narrow opportunity gaps and help children maintain early learning success. Early Learning Network teams are excited to share what they have learned--and what it means for early…

The Language Interaction Snapshot (LISn; Sprachman et al., 2009) was used to measure the quantity and quality of language interactions in English and Spanish in 143 preschool classrooms serving Spanish-speaking dual language learners. Both teachers (n = 112) and assistant teachers (n = 92) were included in analyses with a total of 461…

Quality rating and improvement systems (QRISs) are designed to assess, improve, and communicate the quality of early care and education programs. Using administrative data, we investigated whether providers that participated in a county-level QRIS saw increases to their global quality (tier) rating, domain-specific quality ratings, and scores on…

As a result of patchwork policies, early childhood education (ECE) providers combine funding from multiple sources, known as blended funding. However, little is known about the consequences of blended funding for policy goals. We use national ECE provider data to identify the prevalence of blended funding models, and detailed state quality rating…

High-quality early childhood programs aim to foster children's learning through developmentally appropriate practices and environments. Early childhood assessments, when well designed and well implemented, can support developmentally appropriate early learning experiences by providing information to guide instruction and support whole child…

This study investigates the relationships between preschool quality and children's learning and development from fall to spring of 1 school year through the analysis of child- and program-level data from approximately 70,000 children, ranging in age from 4.5 to 5.5 years old, in 1,700 Quality Counts California (QCC) rated preschool programs, the…

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…

Early childhood education programs (ECE) invest in assessments of classroom quality to enable accountability and to enact efforts towards quality improvement. The "Early Childhood Environment Rating System -- Revised" (ECERS-R) and "Classroom Assessment Scoring System" (CLASS) are two widely used classroom quality assessments…

Using a large sample of longitudinal assessment data from children in publicly funded infant/toddler care, preschool, and kindergarten (analytic N = 453,468), this study modeled language and literacy trajectories from early infancy through kindergarten for dual language learners (DLLs) from homes representing many different languages and their…

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…
