Special Education Substantially Improves Learning: Evidence from Three States

Special education serves more than one in seven U.S. students, yet its causal impact remains understudied. In this paper, we estimate the effect of individualized supports with an event-study design that tracks achievement around initial classification. The research shows students’ scores decline prior to placement and rise sharply afterward. Overall, individualized supports substantially increase learning productivity.

Forecasting the Supply and Demand of Diverse Educators

The increasing diversity of students in Massachusetts makes growing a diverse educator workforce a critical policy goal for the Commonwealth. In recent years, state and local leaders have responded to this challenge with a variety of programs and policy changes. This report details these efforts and their considerable impact to date. However, the findings show the racial and ethnic differences between the state’s students and teachers will continue to widen through the end of this decade, if Massachusetts remains on the current trajectory. Employing a projection model developed by researchers at the Wheelock Educational Policy Center, the analysis models several hypothetical scenarios to close the gap. The report concludes with policy recommendations to accelerate the pace of change.

Deconstructing the EL Gap

Across U.S. schools, students classified as English learners (ELs) tend to achieve lower educational outcomes than their non-EL peers. What explains these differences? Are they a product of ELs’ developing English language proficiency and/or the services they receive at school, or do other factors play a role? The authors of this study attempt to deconstruct the “EL gap” in Massachusetts by examining the extent to which differences in outcomes between ELs and non-ELs can be attributed to factors that are unrelated to a student’s English proficiency or receipt of EL services.

Enrollment Flexibility and Charter School Impacts: The Effect of Backfill on Students in Massachusetts Charter Middle Schools

This study leverages Massachusetts’s adoption of a statewide requirement for charter schools to backfill vacancies within some grades to provide the first causal estimates for the effect of incorporating new students on the performance of incumbent charter school pupils. Using data from the universe of Massachusetts public school students enrolled in Grades 5 through 8 from 2007-2008 to 2013-2014, this study compares changes in student achievement in impacted vs. not-impacted grades within Boston charter schools to the patterns of student achievement within traditional public schools and charter schools outside of Boston.
