Half of kindergarten teachers split children into higher and lower ability groups for reading or math. In national data, we predicted kindergarten ability group placement using linear and ordinal logistic regression with classroom fixed effects. In fall, test scores were the best predictors of group placement, but there was bias favoring girls,…

It is important to understand how longitudinal patterns of special education placement differ from cross-sectional incidence estimates in order to improve measurement precision and better target assistance to students with disabilities. This study used latent class growth analysis in a national-level data set to classify four trajectories of…

Many kindergarten teachers use ability groups to differentiate instruction in reading and math. Ability group placement should depend primarily on student achievement, but critics charge that placement is biased by socioeconomic status (SES), gender, and race/ethnicity. We predict group placement in the Early Childhood Longitudinal Study of the…

In national data, we predicted kindergarten ability group placement using linear and ordinal logistic regression with classroom fixed effects. In fall, test scores were the best predictors of group placement, but there was bias favoring girls,…

Although national legislation and policy call for the use of student assessment data to support instruction, evidence suggests that teachers lack the knowledge and skills required to effectively use data. Previous studies have demonstrated the potential of training for increasing immediate teacher outcomes (i.e., knowledge, skills, and beliefs),…

Background: Ability grouping has resurged in U.S. schools despite long-standing debates over its consequences for educational equity. Proponents argue that it is the best response to variation in academic skills because it allows teachers to customize the content and pace of instruction to students' diverse needs. Critics answer that this practice…

This study investigated how student and school-level socioeconomic status (SES) measures predict students' odds of being identified for special education, particularly high-incidence disabilities. Using the Early Childhood Longitudinal Study--Kindergarten cohort, hierarchical models were used to determine the relations of student and school SES to…

Ability grouping is a common educational practice utilized by elementary teachers during reading instruction. This study examines whether ability grouping operates as a form of educational stratification by examining the following research question: To what extent do student literacy skills, background characteristics, and prior group placement…

The proportion of eighth graders in United States public schools enrolled in algebra or a more advanced mathematics course doubled between 1990 and 2011. This article uses Early Childhood Longitudinal Study's Kindergarten Cohort data to consider the selection process into advanced middle school mathematics courses and estimate the effects of…

Students of color are underrepresented in gifted programs relative to White students, but the reasons for this underrepresentation are poorly understood. We investigate the predictors of gifted assignment using nationally representative, longitudinal data on elementary students. We document that even among students with high standardized test…

This study is a longitudinal look at the different mathematics placement profiles of Black students and White students from late elementary school through 8th grade. Results revealed that Black students had reduced odds of being placed in algebra by the time they entered 8th grade even after controlling for performance in mathematics. An important…

The issue of over or under representation of ethnic minority students in special education placement has received a great deal of attention in recent years. An equally important question that has not received as much attention centers on the impact of special education placement, particularly early in a child's education career, on subsequent…

With tightened school budgets, school administrators need to know the short term and long range effects of providing gifted programs at the elementary level. Programming opportunities in elementary school have direct impact on middle school and this, in turn impacts high school and college course selection. This study used the Early Childhood…

Increased access to algebra was a focal point of the National Mathematics Advisory Panel's 2008 report on improving mathematics learning in the United States. Past research found positive effects for early access to algebra, but the focus on average effects may mask important variation across student subgroups. The author addresses whether these…

The authors analyzed the Early Childhood Longitudinal Study-Kindergarten Cohort (ECLS-K) national data set to investigate gender differences in ability group placement in American kindergartens. They found that in kindergarten, within-class ability grouping was widely used for reading instruction, with boys being underrepresented in high-achieving…
