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,…

Eighteen students, who self-identified as Latinx, from a rural, Midwestern community participated in this study. The participants were enrolled in their high school's "Risk Academy," a program designed for students labeled "at risk." Data shared in this article stem from a larger study where we applied photovoice, a critical,…

The purpose of this study was to investigate the effects of a transition to homogenous ability grouping between secondary grades on MAP test scores in an international private school in Dubai. Participants were students who have been enrolled at PISD for two years for grades 6, 7, 8, or 9 from 2020-2022 and who have presented MAP test scores both…

This case explores the complexities of how consolidation perpetuates stereotypes among different social classes in a rural Appalachian school setting. Examined are the experiences at the intersection of social class in rural U.S. school districts when two communities--one affluent and one underresourced--are consolidated. We present a nuanced…

Ability grouping is a common practice in elementary mathematics instruction, but some research suggests that grouping by ability can exacerbate existing inequities, and there is evidence that alternatives to grouping can improve learning experiences for all students. In this paper, we describe an effort to support teachers in using equitable…

Effects of full-time ability grouping on students' academic self-concept (ASC) and mathematics achievement were investigated in the first 3 years of secondary school (four waves of measurement; students' average age at first wave: 10.5 years). Students were primarily from middle and upper class families living in southern Germany. The study sample…

Facilitating a more responsive style of teaching in primary mathematics has implications for not only teaching practice, but also for how we plan for our learners. Grouping decisions, task selection and teacher confidence in mathematical content are important considerations when developing inquiring mathematical communities. This article…

Background: For the last century, the dominant practice in U.S. high schools has involved sorting students by perceived ability level, yet 40 years of research has yielded consistent evidence that these practices harm the learning of students placed in lower-level classes; evidence is inconsistent about benefits for students in classes designated…

Teachers often group students into teams to organize their classrooms and network-informed interventions hold great promise as a way to facilitate positive peer influence and promote the diffusion of intervention effects. Yet thus far, relatively little research has explored how teachers or prevention scientists can best use social network…

The knowledge base on various forms of structuring students' learning by ability grouping is more robust than that on teachers' instructional practices being implemented within these groupings. The present study examines if student-reported mathematics teachers' instructional practices vary among schools with different degrees of implementing…

With the rise of accountability policies since the early nineties, the daily operation of English schools has profoundly changed. Through the in-depth analysis of ability grouping practices in one English secondary school, this paper aims to explore how the accountability shift and datafication impacted the practice of student grouping and…

Both in New Zealand and internationally, there has been a focus on the use of differentiation in mathematics instruction to raise achievement levels and provide equitable outcomes. New Zealand has a long history of the use of ability grouping to provide differentiation. Recently, this practice has been challenged in a large scale professional…

Grouping pupils by attainment is frequently practised in primary schools yet is associated with detrimental effects for middle- and lower-attaining children. Drawing on a mixed methods study, we find that attainment grouping practices at key stage 2 in primary schools are seldom straightforward. Although grouping by attainment appears to be the…

After reviewing curriculum materials and observing instructional practices, the author identified trends and issues in school districts related to the implementation of differentiated curriculum and stakeholders' views. Although primary stakeholders hold positive views of a differentiated curriculum, limited differentiation is being used in the…

Despite research demonstrating that attainment-based grouping has little, if any, overall benefits there is an increasing trend towards ability grouping in the early years. Using an ethnographic case study the article demonstrates how different pedagogical approaches are used with different 'ability' groups. The pedagogical experiences of…
