The current study provides new evidence on the sustained benefits of preschool attendance on a broader range of skills--both academic and executive functioning (EF)--than many prior studies have examined. Using propensity score methods, we predicted children's (N = 920, M age at 1st = 6.5 years) literacy, language, math, and EF skills in…

Although universal social-emotional learning programs are increasingly implemented across the USA, few studies have examined the effects of sustained exposure to the same program across multiple grade levels. As such, the goal of this study was to isolate the effects of sustained exposure to a universal social-emotional learning program (Elliott…

The purpose of this study was to evaluate the efficacy of a universal social skills program, the Social Skills Improvement System Classwide Intervention Program (SSIS-CIP; Elliott & Gresham, 2007), for students in first grade. Classrooms from 6 elementary schools were randomly assigned to treatment or business-as-usual control conditions.…

A growing body of research has shown that high quality early care and education (ECE) is positively related to the development of children's social and academic skills (e.g., Barnett, 2011; Lamb & Ahnert, 2006; NICHD ECCRN, 2006). There is evidence that high quality ECE experiences can improve children's levels of social adjustment (Bierman et…

California's Kindergarten Readiness Act of 2010 established transitional kindergarten (TK), the first year of a two-year kindergarten program for students affected by the change in the birthdate cutoff for entry into kindergarten from December 2 to September 1. This final report from the program's evaluation focuses on results from a five-year…

California's Kindergarten Readiness Act of 2010 established transitional kindergarten (TK), the first year of a two-year kindergarten program for students affected by the change in the birthdate cutoff for entry into kindergarten from December 2 to September 1. This fifth short report in a series highlighting findings from the Study of…

This article examined the efficacy of a primary-level, standard-protocol behavior intervention for students with externalizing behavioral disorders. Elementary schools were randomly assigned to treatment (behavior intervention) or control (business as usual) conditions, and K-3 students were screened for externalizing behavior risk status. The…

Teacher perceptions about students' academic abilities are important for several reasons (e.g., instructional decision making, special education entitlement decisions). Not surprisingly, researchers have investigated the accuracy of teachers' decisions. Although some data reveal that teachers are relatively good judges of academic performance,…

This study was designed to increase student empowerment through the use of formative assessment. The targeted population consisted of first and fifth grade students in the same school. Evidence for the existence of the problem included teacher observation, students' lack of knowledge and skills to complete classroom assignments, and low test…
