State laws that mandate in-grade retention for struggling readers are widespread in the U.S., covering 34% of public-school third graders in 2023-24. This study investigates the impacts of Michigan's third-grade reading law on subsequent test scores and school progress outcomes for the 2020-21 and 2021-22 third-grade cohorts. Using a regression…

The purpose of this qualitative study is to determine how four rural school districts in East Tennessee worked to implement the third-grade retention law within their understanding and interpretation of the law to the benefit of the students and overall communities they serve. The study used a semi-structured questionnaire format conducted with a…

We propose a novel estimator for use in a fuzzy regression discontinuity setting. The estimator can be thought of as extrapolating the traditional fuzzy regression discontinuity estimate or as an observational study that adjusts for endogenous selection into treatment using information at the discontinuity. We show that it can be motivated as…

We evaluate the effects of grade retention on students' academic, attendance, and disciplinary outcomes in Indiana. Using a regression discontinuity design, we show that third-grade retention increases achievement in English Language Arts (ELA) and math immediately and substantially, and the effects persist into middle school. We find no evidence…

The internal validity of observational study is often subject to debate. In this study, we define the counterfactuals as the unobserved sample and intend to quantify its relationship with the null hypothesis statistical testing (NHST). We propose the probability of a robust inference for internal validity, that is, the PIV, as a robustness index…

Background: Grade retention is an educational aspect that concerns teachers, families, and experts. It implies an economic cost for families, as well as a personal cost for the student, who is forced to study one more year. The objective of the study was to evaluate the effect of course repetition on math, science and reading competencies, and…

Grade-level retention is a common educational practice with the goal of improving academic performance, but the evidence of its influence is mixed. This study examines the academic effect of repeating kindergarten, first grade, second grade, or third grade on English Language Arts performance at the end of fourth grade. This study also examines…

In this pre-registered study, we explored the impacts of Boston Pre-K on children's educational trajectories, school progress/engagement, and academic achievement in late elementary and middle school using lotteries for oversubscribed schools in 2007-2011 (N=3,092 students; 24% of all applicants). Importantly, the program was unique nationally in…

The Education Policy Innovation Collaborative (EPIC) has been working closely with the Michigan Department of Education (MDE) and the Center for Educational Performance and Information (CEPI) to study the implementation and outcomes of Michigan's Read by Grade Three Law in real-time as the policy takes effect. Between 2021 and 2023, the Law…

In a large school district in Florida, many third-grade students have been retained over a 7-year period. Enrollment documents, such as summer school registration forms and seven annual summer reading camp evaluations in 2013-2019, indicated that 13,693 students attended the 4-week summer reading camp during this period. Summer reading camps are…

Much of the existing educational research has focused on affluent Western societies. Despite comprising a broad swathe of the world population, less work has focused on lower middle-income economies such as the Philippines. Perhaps part of this reason is the lack of high-quality data in such contexts. PISA provides a potential solution to this…

In recent decades, state policymakers across the country have turned to early literacy policies to address students' reading proficiency--particularly in third grade. Though states' policies vary widely in terms of the interventions and supports provided to educators and students, their intent is similar: to get students reading on grade level by…

This study was designed to examine the effects of grade level retention on students' reading achievement, based on the State of Texas Assessment of Academic Readiness (STAAR). Three research questions guided the study. Did students who were retained in kindergarten, first, or second grade reach academic success on 5th grade reading STAAR? Did…

Public policies often target individuals but within-family externalities of such interventions are understudied. Using a regression discontinuity design, we document how a third grade retention policy affects both the target children and their younger siblings. The policy improves test scores of both children while the spillover is up to 30% of…

Mandatory grade retention for poor-performing readers has been a disputed practice for decades. Since the early-2000s, state-level mandatory grade retention policies have proliferated. In 18 states and Washington, D.C. mandatory grade retention exists for students in the third-grade who fail an end-of-year standardized reading exam. These policies…
