This secondary analysis study examined patterns, predictors, and outcomes of dual language learners' (DLLs') development in Spanish and English. Research Findings: Latent profile analysis identified three groups of DLLs: Balanced Bilinguals (54%), English-Dominant Bilinguals (25%), and Spanish-Dominant Bilinguals (21%). These groups had fairly…

Research Findings: Peer play interactions are important contexts for supporting early learning both at home and at school for preschool children from low-income backgrounds. The current study used structural equation modeling to examine whether teacher-reported learning behaviors in the classroom mediated the relationship between parent-reported…

Despite research demonstrating the importance of mathematics achievement to children's educational success and trajectories, many children enter kindergarten without the foundational mathematics skills needed to succeed (Garcia & Weiss, 2015). Children's executive function (EF) skills and their learning-related behaviors (Anthony & Ogg,…

The purpose of this study was to examine associations between attendance in Georgia's Pre-K Program and children's academic and social outcomes through third grade. This report includes a sub-study that incorporates a comparison group of children who did not attend any pre-k program. This report focuses on third grade outcomes, but it also…

This report summarizes results from the Georgia's Pre-K Longitudinal Study Third-Grade Report. The study followed a representative sample of children (n=1,169) from their pre-k experience (2013-2014) through the third grade (2017-2018). Study components include: (1) Standardized child assessments that measure skills across learning domains. By…

General measures of process quality are widely used in the early childhood education (ECE) field. However, the evidence regarding associations between the most widely used process quality measure, the Classroom Assessment Scoring System (CLASS; Pianta et al., 2008), and children's school readiness gains during the preschool year is mixed. Using…

Research Findings: Using a nationally representative sample of Head Start recipients, this study compared Head Start classroom contexts and English language and literacy skill trajectories for Spanish-speaking dual-language learners (DLLs) and English speakers from preschool through kindergarten. It also examined whether Head Start classroom…

The primary purpose of the 2017-2018 NC Pre-Kindergarten (NC Pre-K) Evaluation was to examine the effectiveness of the NC Pre-K Program using a randomized controlled trial (RCT) design. The major issue addressed by this type of study is around the benefits of offering children access to enrollment in NC Pre-K. An RCT is considered the…

The standard scoring of the CLASS PreK produces three domain scores that are widely used in research, practice and policy. Despite these domains being based on developmental theory and research, limited empirical evidence exists for the three-domain structure as operationalized in the CLASS PreK. Using the 2009 and 2014 Head Start Family and Child…

The purpose of the 2015-2016 NC Pre-Kindergarten (NC Pre-K) Evaluation study was to examine the long-term effects of participation in NC Pre-K at the end of kindergarten. Two groups of children were compared--those who attended NC Pre-K (treatment) and those who had not attended NC Pre-K (comparison). Propensity score matching (PSM) was used to…

The purpose of the 2014-2015 North Carolina Pre-Kindergarten (NC Pre-K) Evaluation study was to examine the characteristics and quality of the program and the outcomes for children during Pre-K, along with comparisons to previous years. NC Pre-K is a state-funded educational program for eligible 4-year-olds, designed to enhance their school…

This executive summary presents results from a study that began in 2013-2014, and involves a longitudinal design to follow a sample of 1,169 children (139 Spanish-speaking DLLs) who attended 199 randomly-selected Georgia's Pre-K classrooms. These findings focus on results from the second year of the study, which included 1,034 of these children…
