This study examined the effect of small class size intervention on student outcomes using reading achievement scores as measured by the Comprehensive Test of Basic Skills (CTBS), a standardized, norm-referenced test, while controlling for independent variables inclusive of students' gender, race, socioeconomic status (SES), and environment. This…

There is empirical evidence of substantial heterogeneity in economic mobility across geographic areas and the efficacy of schools has been suggested as an explanatory factor. Using administrative microdata from seven states covering nearly 3 million students, we explore the potential role of schools in promoting economic mobility by estimating…

In this paper, we use NWEA MAP test data to examine variation in students' achievement and growth during the pandemic across multiple dimensions. Consistent with prior evidence, we find that students' test scores in fall 2021, on average, were substantially below historic averages. Moreover, the average scores of students of color, students…

The academic achievement gap is a persistent and pernicious educational challenge confounded with race and socioeconomic status. The achievement gap persists despite over three decades of interventions and federal, state, and local policies and initiatives meant to close it. We examine the achievement gap in one of the most diverse states in the…

School buses may be a critical education policy lever, breaking the link between schools and neighborhoods and facilitating access to school choice. Yet little is known about the commute for bus riders, including the average length of the bus ride or whether long commutes harm academic outcomes. We begin to fill this gap using data from New York…

The purpose of this study was to identify an indicator that the School District of Philadelphia (SDP) could use to measure the percentage of entering kindergarteners who are on-track to read on grade level by the end of grade 3. To develop the indicator, this study examined relationships between student scores on SDP's different assessments that…

This study examined the influence of grouping formation on the scores on the New Jersey Assessment of Skills and Knowledge (NJASK 3) in Grade 3 English Language Arts. Grouping within the general education classroom was compared to grouping between the same grade level. The analysis included a multiple regression model for student variables gender,…

Test-score data show that both low-income and racial-minority children score lower, on average, on states' elementary-school accountability tests compared with higher-income children or white children. This report explores the relationship between racial and socioeconomic test-score gaps in New England metropolitan areas and two factors associated…

A data set from an urban Midwestern school district was mined to explore how the technology-based reading enrichment known as Mindplay Virtual Reading Coach (MVRC) affects children's performance on the English Language Arts (ELA) Standards state-wide assessment (N = 6098 students from Grades 3 to 9). ELA data from two times points were available,…

A comparison of Chicago public school students' standardized test scores in 2009-2014 with those of public students across the U.S. reveals two striking patterns. First, Chicago students' scores improved dramatically more, on average, between third and eighth grade than those of the average student in the U.S. This is true for students of all…

I use standardized test scores from roughly 45 million students to describe the temporal structure of educational opportunity in over 11,000 school districts--almost every district in the US. For each school district, I construct two measures: the average academic performance of students in grade 3 and the within-cohort growth in test scores from…

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…

Public schools with impressive records of serving lower-performing students are often overlooked because their average test scores, even when students are growing quickly, are lower than scores in schools that serve higher-performing students. Schools may appear to be doing poorly either because baseline achievement is not easily accounted for or…

New York mayor Bill de Blasio entered office in January 2014, promising to "take dead aim at the Tale of Two Cities … [and] put an end to economic and social inequalities that threaten to unravel the city we love." The Manhattan Institute's "Poverty and Progress in New York" series tracks the effects of Mayor de Blasio's…

The purpose of this report is to describe the technical qualities of the 2018-2019 operational administration of the English language arts/literacy (ELA/L) and mathematics summative assessments in grades 3 through 8 and high school. The ELA/L assessments focus on reading and comprehending a range of sufficiently complex texts independently and…
