The Equality of Educational Opportunity Study (1966)--the Coleman Report--lodged a key takeaway in the minds of educators, researchers, and parents: Schools do not strongly shape students' achievement outcomes. This finding has been influential to the field; however, Coleman himself suggested that--had longitudinal data been available to…

Executive function skills are a set of cognitive processes that help individuals to engage in goal-directed behavior and have been linked to benefits in academic achievement and other learning-related outcomes. Recently, there has been interest in understanding how attending center-based preschool may relate to the development of executive…

What is schools' role in the stratification system? One view is that schools are an important mechanism for perpetuating inequality because children from advantaged backgrounds (white and high socioeconomic) enjoy better school learning environments than their disadvantaged peers. But it is difficult to know this with confidence because children's…

This study examines the effects of the summer period on value-added assessment (VAA) of teacher and school performance at the early grades. The results indicate that 40-62% of the variance in VAA estimates originates from the summer, depending on the outcome. Furthermore, when summer is omitted from the VAA model, 51-61% of the teachers and 58-61%…

Despite growing interest in the importance of nonacademic skills for student success, very few studies have examined the extent to which schools and teachers are associated with gains in these outcomes. This descriptive study adds to the nascent literature by examining the amount of school- and teacher-associated variation in kindergarten…

This study examines the effects of including the summer period on value-added assessments (VAA) of teacher and school performance at the early grades. The results indicate that 40-62% of the variance in VAA estimates originates from the summer period, depending on the outcome (i.e., reading or math achievement gains). Furthermore, when summer is…

This article introduces a multilevel growth mixture model (MGMM) for classifying both the individuals and the groups they are nested in. Nine variations of the general model are described that differ in terms of categorical and continuous latent variable specification within and between groups. An application in the context of school effectiveness…

The authors investigated whether age at kindergarten entry was associated with early literacy achievement gaps and if these gaps persisted over time. Using the kindergarten age eligibility cutoff date, they created 2 groups of students who represented the oldest and youngest children in a cohort of students in high-poverty, low-performing schools.…

This paper reports on a study conducted to investigate the consistency of the results between 2 approaches to estimating school effectiveness through value-added modeling. Estimates of school effects from the layered model employing item response theory (IRT) scaled data are compared to estimates derived from a discrete growth model based on the…
