We studied the effect of the number and characteristics of siblings (sex, age) on school achievement in several grades (kindergarten, first grade, and fifth grade), in two large French cohorts, with more than 16,000 children. Running linear mixed-effects models, we find that, independently of socioeconomic status, having more siblings is…

This article proposes a latent variable regression four-level hierarchical model (LVR-HM4) that uses a fully Bayesian approach. Using multisite multiple-cohort longitudinal data, for example, annual assessment scores over grades for students who are nested within cohorts within schools, the LVR-HM4 attempts to simultaneously model two types of…

Every country strives for its students to have advanced achievement in some way, shape, or form. But too often, competence is a higher policy priority than excellence, and shrinking minimum competency gaps is a higher priority than closing excellence gaps. In this brief, educational excellence is defined as the percent of students who meet or…

This is a causal comparative research study that investigates the effects of poverty on student academic achievement within various subgroups in Nassau and Suffolk counties on Long Island, NY. Existing data for approximately 124 school districts from the published New York State Report Card (NYSRC) were used to operationalize the study. The…

This report explores a new latent variable regression 4-level hierarchical model for monitoring school performance over time using multisite multiple-cohorts longitudinal data. This kind of data set has a 4-level hierarchical structure: time-series observation nested within students who are nested within different cohorts of students. These…

While parental involvement's effect on student achievement has been explored in current research, and the relationship among parent, teacher, and student is often discussed, no definite guidelines have been stipulated for successful engagement between the three. The purpose of this project was to examine parental involvement practices…

The study analyzes the achievement trends of all third grade students in the state of Illinois who scored in the Exceeds category in reading and mathematics on the Illinois Standards Achievement Test (ISAT) in the year 2000. ISAT performance of this cohort group of students was followed through the eighth grade. Descriptive analyses were utilized…
