Program and policy effects

English-only college education in non-English speaking countries is a rapidly growing phenomenon that has been dubbed as the most important trend in higher education internationalization. Despite worldwide popularity, there is little empirical evidence about how the transition to English-only instruction affects students’ academic outcomes. Using a natural experiment at a selective university in Central Asia and a difference-in-differences strategy, we estimate the causal effect of switching to English-only instruction on students’ college outcomes. We find that the introduction of English-only instruction led to a decrease of GPAs and probability of graduation and an increase in the number of failed course credits. Although negative, the effects were short-lived. The difference-in-differences estimates and the examination of potential mechanisms suggest that at least in selective universities in non-English speaking countries, the switch to English-only instruction may affect college outcomes negatively at the time of transition but may not necessarily imply longer-run negative effects.

Prior research has shown that EL classification is consequential for students, however, less is known about how EL classification impacts students’ outcomes. In this study, we examine one hypothesized mechanism: teacher perceptions. Using nationally-representative data (ECLS-K:2011), we use coarsened exact matching to estimate the effect of EL status on teachers’ perceptions of students’ skills in language arts, math, science, and social studies in kindergarten through second grade. We further explore whether that impact is moderated by instructional setting (bilingual versus English immersion). We find evidence that EL classification results in lower teacher perceptions across content areas and grade levels. This impact is, however, moderated by bilingual environments. This study adds to research on teacher perceptions and the effects of EL classification.

The vast majority of literature on school choice, and charter schools in particular, focus on attending an elementary or middle school and often focus on test scores or other proximal outcomes. Much less is known about the long-term effects of attending a charter high school. It is important to fill this information void for a few reasons. First, schools in general affect more than just students’ test scores. Second, high schools make up a larger share of the charter sector. Third, school choice depends on freely available information for parents and students to make informed decisions about where to attend, including potential long-term benefits. We add to the empirical research on charter school effects by using a doubly-robust regression-adjusted propensity score matching approach to evaluate the impacts of charter high school attendance on 9th grade behavioral outcomes and individuals propensity to commit crime and participate in elections as young adults in North Carolina, a state with a large and growing charter school sector.

Student loan borrowing for higher education has emerged as a top policy concern. Policy makers at the institutional, state, and federal levels have pursued a variety of strategies to inform students about loan origination processes and how much a student has cumulatively borrowed, and to provide students with greater access to loan counseling. We conducted an experiment to evaluate the impact of an outreach campaign that prompted loan applicants at a large community college to make informed and active borrowing decisions and that offered them access to remote, one-onone assistance from a loan counselor. The intervention led students to reduce their unsubsidized loan borrowing by 7 percent, resulted in worse academic performance, and increased the likelihood of loan default during the three years after the intervention occurred. Our results suggest policy makers and higher education leaders should carefully examine the potential unintended consequences of efforts to reduce student borrowing, particularly in light of growing evidence regarding the counter-intuitive positive relationship between reduced borrowing levels and worse student academic and financial outcomes.

In the forty plus years since passage of the Individuals with Disabilities Education Act (IDEA), special education has grown in the number of students and amount spent on services. Despite this growth, the academic performance of students with disabilities (SWDs) remains troubling low compared to general education students (GENs). To some extent, these differences reflect persistent underlying disabilities, but they may also reflect ineffective special education services. Does special education improve academic outcomes for students with disabilities? There is surprisingly little evidence to guide policy and answer this question. This paper provides an answer for the largest disability group, students with learning disabilities (LDs), using rich data from New York City public schools. Because the majority of LDs are classified after school entry, we observe outcomes both before and after classification, allowing us to gauge impact using within-student pre/post comparisons and, ultimately, student fixed effects in regression models exploring impacts. We find that academic outcomes improve for LDs following classification into special education, and impacts are largest for those entering special education in earlier grades. Results are robust to alternative specifications and falsification tests bolster confidence in a causal interpretation. Differences in impacts by gender and race/ethnicity, grade of classification, and settings shed light on possible mechanisms.

In this paper we estimate the impacts of the “pathways” chosen by community college students—in terms of desired credentials and fields of study, as well as other choices and outcomes along the paths—on the attainment of credentials with labor market value. We focus on the extent to which there are recorded changes in students’ choices over time, whether students make choices informed by their chances of success and by labor market value of credentials, and the impacts of choices on outcomes. We find that several characteristics of chosen pathways, such as field of study and desired credential as well as early “momentum,” affect outcomes. Student choices of pathways are not always driven by information about later chances of success, in terms of probabilities of completing programs and attaining strong earnings. Students also change pathways quite frequently, making it harder to accumulate the credits needed in their fields. Attainment of credentials with greater market value could thus likely be improved by appropriate guidance and supports for students along the way, and perhaps by broader institutional changes as well.

Research has begun to investigate whether teachers and schools are as effective with certain student subgroups as they are with the overall student population.  Most of this research has examined the issue by trying to produce causal estimates of school contributions to short-term student growth (usually using value-added models) and has emphasized rank orderings of schools by subgroup.  However, not much is known about whether schools contributing to long-term growth for all students are also contributing to student growth by subgroup in ways that might close achievement gaps.  In this study, schools’ contributions to student growth are estimated separately for Black versus White students.  Results show that focusing on rank orderings of schools alone can mask troubling trends in relative achievement over time.  Options for how policymakers can sensibly hold schools accountable for student growth, including under The Every Student Succeeds Act, are discussed.

This study is a randomized control trial of full- versus half-day pre-kindergarten in a school district near Denver, Colorado. Four-year-old children were randomly assigned an offer of half-day (four days/week) or full-day (five days/week) pre-k that increased class time by over 600 hours. The offer of full-day pre-k produced substantial, positive effects on children’s receptive vocabulary skills (0.267 standard deviations) by the end of pre-k. Among children enrolled in district schools, full-day participants also outperformed their peers on teacher-reported measures of cognition, literacy, math, and physical development. At kindergarten entry, children offered pre-k still outperformed peers on a widely-used measure of basic literacy. The study provides the first rigorous evidence on the impact of full-day preschool on children’s school readiness skills.

The well-documented racial disparities in school discipline have led many school districts in the U.S. to adopt restorative justice practices. The restorative justice philosophy differs from traditional disciplinary action by placing an emphasis on restitution and improving behavior rather than punishment. While models of restorative justice are descriptively and theoretically promising, research on restorative practices in schools is limited. We use student-level administrative data and a difference-in-difference design to measure the changes in student discipline outcomes that occurred under restorative justice in Pacific City schools between the 2008-2017 school years. Results indicate that restorative justice practices led to an overall reduction in disciplinary action. However, results also show that restorative justice practices had differential effects between racial groups, with White students benefiting most from restorative justice. These findings suggest that while the overall effects of restorative justice are promising, these practices may unintentionally widen the racial disproportionality in school discipline they are instituted to mitigate.

Estimates of school voucher impacts on educational attainment have yet to explore heterogeneities in socioeconomic status among disadvantaged minority students. We theorize reasons for these heterogeneities and then estimate experimentally the differential impacts of voucher offers on college enrollment and graduation rates for minority and non-immigrant students from moderately and severely disadvantaged backgrounds. The findings are obtained from a privately sponsored, lottery-based voucher intervention in New York City that began in 1997. College enrollment and degree attainment as of the fall of 2017 were obtained from the National Student Clearinghouse. We find no significant effects of offers on minority students from severely disadvantaged backgrounds but significant effects of six to eight percentage points on those from moderately disadvantaged households. Similar results are obtained for students born of non-immigrant mothers. Some policy implications are discussed.
