We used the Stanford education data archive (SEDA) data to examine the heterogeneity among urban school districts in the United States. The SEDA 2.1 includes data sets on students' mathematics (Math) and English language arts (ELA) achievement from 2008 to 2014 at the district level. Growth mixture modeling was used to uncover the underlying…

Closing the achievement gap has been a continuous topic of conversation in the United States for decades. School leaders have explored many ways to address the academic achievement of their marginalized student population. One approach has been the implementation of culturally relevant pedagogy and curriculum. By implementing a curriculum in which…

This study focused on a problem of practice at Mystic River School (MRS), a kindergarten through eighth grade school in an urban district in New England. Schoolwide diagnostic data showed a significant gap between multilingual learners (MLs) and their native English speaking peers in literacy. An analysis of this data, interviews with staff and…

We study the distributional effects of remote learning using a novel approach that combines preference data from a conjoint survey experiment with administrative records of student outcomes. The experimentally derived preference data allow us to account for selection into remote learning while also studying selection patterns and treatment effect…

This study compared the summer learning rates of students who attended Houston Independent School District (HISD) 2016 summer school to similar students who did not attend, for both promoted and retained students. For students between 1st and 2nd grade and those between 2nd and 3rd grade, summer learning rates were faster for both promoted and…

Using a DisCrit intersectional lens and statistical and spatial methods, we trace how the creation of K-8 schools functioned to create pockets of privilege in one urban U.S. school district. K-8 schools were both whiter and wealthier than district averages, serving as "enclave" schools. Although far fewer students with disabilities were…

This article explores inequity in access to and provision of bus service across student sociodemographic groups and examines possible barriers to bus access and utilization. To so do, we use administrative data on New York City K-6 public school students from 2011-2017, including information on race/ethnicity, poverty status, distance from home to…

In November 2014, the New York City Department of Education classified 94 low-performing schools as "renewal schools." New York's Renewal School Program (RSP), announced Mayor Bill de Blasio at the program's launch, represented a big change to the city's education policy: whereas former mayor Michael Bloomberg favored closing failing…

Principals' beliefs and actions have powerful outcomes in the lives of the students and families they serve. In this article, we offer the portrait of a long-standing principal of a diverse urban school where the student body is 90% Latinx, 65% English learners (ELs), and 87% eligible for free or reduced-price lunch. We explore many key practices…

Two decades ago, the New Jersey Supreme Court in "Abbott v. Burke" mandated that the state establish high quality preschool education in the 31 highest-poverty school districts. New Jersey created a pre-K program with high standards and a continuous improvement system that transformed a patchwork of private and public programs into a…

Using testing data from 2.1 million students in 10,000 schools in 49 states (plus D.C.), we investigate the role of remote and hybrid instruction in widening gaps in achievement by race and school poverty. We find that remote instruction was a primary driver of widening achievement gaps. Math gaps did not widen in areas that remained in-person…

Inquiry-based science interventions aim to improve students' science proficiency by helping them understand scientific processes. In these interventions, students conduct hands-on investigations of science concepts and everyday phenomena, construct explanations for what they observe, consider alternative explanations, and communicate and justify…

This report examines how students are performing across the entire 2020-2021 school year in reading and mathematics during the pandemic. Based on insights from millions of student assessments, the report explores key questions effected by COVID-19 in education, including: (1) How much did students grow during the 2020-2021 school year compared…
