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…

Legislative frameworks in England have been designed to support children with special educational needs and disabilities (SEND). Despite efforts from policy makers, achievement gaps persist between students with SEND and their typically developing peers. This study examines the extent and persistence of academic achievement gaps between students…

Michigan's Great Start Readiness Program (GSRP) is a state-funded pre-K program that serves at risk four-year-old children across the state. Utilizing longitudinal data from 1,394 children in a mid-sized urban school district, we conducted regression analyses and piecewise linear growth models to examine the growth trajectory of GSRP children and…

This paper presents evidence of the effects of dual language immersion (DLI) programs on the academic outcomes of students in elementary grades. Leveraging enrollment lotteries from four cohorts of DLI applicants across 10 oversubscribed programs, analyses estimate the intent-to-treat effect of access to bilingual education on reading and math…

Student mobility that occurs within a school year may be especially disruptive for student outcomes, yet little is known regarding the predictors of within-year mobility. In particular, research has yet to comprehensively examine the role of student achievement in predicting within-year student mobility. Thus, we sought to understand this link by…

This study compares latent profiles derived from student subgroups of varying levels of mathematical skills defined by achievement and ability assessment scores. Achievement and ability cut scores for identifying students at both ends of the mathematics spectrum were applied and the resulting latent profiles within each condition were compared.…

Because standardized tests in science are not given to PreK-3 students in Ohio, this report examined the longitudinal effects of learning from a teacher who had participated in the NURTURES professional development program. Specifically, it looked at the effects on students' mathematics and reading learning in grades 2-5 and science learning in…

Cambodian primary schools shifted to remote teaching for extended periods during the 2020-21 COVID-19 pandemic. The results from national learning assessments of grade 6 students show that overall averages in Khmer language and mathematics in 2021 were 0.30-0.75 standard deviations below 2016 levels. There is some evidence that learning gaps…

This is the sixth report in a series prepared and delivered to the governor and the Senate and House standing committees responsible for education law in the Michigan legislature. It is designed to help interpret and contextualize assessment results and students' progress toward learning goals in the wake of the COVID-19 pandemic. Our analyses…

Summer learning loss is a perennial concern for educators and parents alike. However, researchers have recently questioned whether summer learning loss is just a statistical artifact driven by how achievement is measured across the school year. In this study, we empirically investigated a plausible critique of summer learning loss research, namely…

This study investigated the long-term impact of the science writing heuristic (SWH) approach on students' science achievement, focusing on differences between low and high socioeconomic status (SES) groups. Through a longitudinal design, students were divided into control and treatment (at least 1 year of SWH) groups. Polynomial growth mixed…

Based on the 2016 Progress in International Reading Literacy Research (PIRLS) data, this study determined the contextual characteristics that distinguished Moroccan fourth-grade kids with high- and low-achieving reading abilities. The PIRLS 2016 public dataset included 5446 Moroccan pupils, with 1545 scoring well and 3901 doing poorly on the…

This dissertation investigates the impact of attending a STEM-designated elementary school on students' math, ELA (English Language Arts), and science achievement and growth scores. As technology continues to advance in education, educators are exploring innovative instructional methods. With a concerning decline in math proficiency nationwide,…

While America is becoming increasingly diverse, educational stakeholders seek programs that address varied language and cultural needs, which is reflected by the growing popularity of dual language immersion (DLI) programs in recent decades. The problem is an extensively persistent academic achievement gap between students with native English and…

Many studies have been done on the short-term academic impacts of early-childhood education programs. The purpose of this study was to add to the educational literature on long-term impacts of early-childhood education programs by analyzing the long-term academic impacts that such programs had on students by the end of third grade. The variable of…
