Background/Context: Closing achievement gaps is a major concern in U.S. education. These gaps can develop in a wide range of ways over the course of a student's schooling. Yet, research on school effectiveness and accountability policies for schools often focuses on rank orderings of schools based on value-added models, which could mask those…

Background/Context: Each year, large shares of students who could do well in Advanced Placement courses and exams--known as AP potential students-- do not participate, particularly students of color and low-income students. There are a number of prevailing reasons, both structural (schools do not offer the courses or teachers do no accurately…

Background: Private schools have a big part in the educational landscape in the United States, both in terms of the number of students they educate and in the number of resources they command. That said, despite expectations to increase equity and access to opportunity for all students, little is known about racial, gender, or socioeconomic…

Background/Context: Achievement gaps motivate a range of practices and policies aimed at closing those gaps. Most gaps studies assume that differences in observed test scores across subgroups are measuring differences in content mastery. For such an assumption to hold, students in the subgroups being compared need to be giving similar effort on…

Background/Context: Scholars have attributed the underperformance of U.S. students relative to students in other high-income countries to unequal access to high-quality educational environments. Poor students are presumed to do disproportionately worse on international achievement tests and, consequently, to pull down the U.S. average. Conversely,…

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…

Background/Context: Underprepared students at community colleges are often assigned to a sequence of developmental education courses that can substantially delay, or even halt, their progress to degree completion. In 2014, Florida implemented a comprehensive reform under Senate Bill (SB) 1720 that allowed the majority of incoming students to…

Background: Value-added modeling (VAM) has been used to rank teachers and assess teacher and school quality. The apparent relationship between value-added teacher rankings and gains in student performance provide a foundation for the view that the contribution of teachers to student performance is the largest factor influencing student…

Background: Student support systems have become a permanent structure in most U.S. public schools, responsible for ensuring equal access to support services. Typically utilized before special education is deemed necessary, these supports often include a range of school- and community-based services such as tutors, mentors, out-of-school time…

Background/Context: There is broad agreement about the benefits of taking AP and/or IB courses in high school. Nonetheless, student access to such courses remains uneven and inequitable, due largely to the practice of tracking students by perceived "ability." These tracking practices are often defended based on the contention that…

Background/Context: In this article we explore equity issues related to school district decision-making about students' opportunities to learn algebra. We chose algebra because of the important role it plays in the U.S. as a gatekeeper to future academic success. Current research has not yet explored issues of equity in district-level…

Background/Context: The challenges documented in the literature on research-practice partnerships and similar school-university collaborations are outlined in the literature review in this issue. Yet only a collaboration among multiple educational and community organizations could create a synergy powerful enough to achieve the multifaceted goals…

Background/Context: Past research has examined many factors that contribute to the black-white achievement gap. While researchers have shown that teacher perceptions of students' academic ability is an important contributing factor to the gap, little research has explored the extent to which teacher perceptions of students' academic ability are…

This chapter summarizes a set of research studies that focus on high school course offerings, takings, and effects. Improving high school experiences and having students graduate from high school ready for college are national priorities under President Obama's Race to the Top initiative. Doing so by expanding access to advanced courses dates back…

Background/Context: Despite decades of research, the persistence of the gap in student achievement between disadvantaged minority students and their middle-class peers remains unexplained. Purpose/Objective: The purpose of the current article is to propose a new model of the achievement gap. Research Design: Data were analyzed from three…
