The COVID-19 pandemic initially resulted in an unanticipated and near-universal shift from in-person to virtual instruction in spring 2020. During the 2020-21 school year, schools began to re-open and families were faced with decisions regarding the instructional mode for their children. We leverage administrative, survey, and virtual-learning data to examine the determinants of family learning-mode choice and the effects of virtual education on student engagement and academic achievement. Family preference for virtual (versus face-to-face) instruction was most highly associated with school-level infection rates and appeared relatively uniform within schools. We find that students who were assigned a higher proportion of instructional days in virtual mode experienced higher rates of attendance, but also negative student achievement growth compared to students who were assigned a higher proportion of instructional days in face-to-face mode. Students belonging to marginalized groups experienced more positive associations with attendance but were also more likely to experience lower student achievement growth when assigned a greater proportion of instructional days in virtual mode. Insights from this study can be used to better understand family preference as well as to target and refine virtual learning in a post-COVID-19 society.

We use publicly available, longitudinal data from Washington state to study the extent to which three interrelated processes—teacher attrition from the state teaching workforce, teacher mobility between teaching positions, and teacher hiring for open positions—contribute to “teacher quality gaps” (TQGs) between students of color and other students in K–12 public schools. Specifically, we develop and implement an agent-based model simulation of decisions about attrition, mobility, and hiring to assess the extent to which each process contributes to observed TQGs. We find that eliminating inequities in teacher mobility and hiring across different schools would close TQGs within 5 years, while just eliminating inequities in teacher hiring would close gaps within 10 years. On the other hand, eliminating inequities in teacher attrition without addressing mobility and hiring does little to close gaps.

High school graduation rates in the United States are at an all-time high, yet many of these graduates are deemed not ready for postsecondary coursework when they enter college. This study examines the short-, medium-, and long-term effects of remedial courses in middle school using a regression discontinuity design. While the short-term test score benefits of taking a remedial course in English language arts in middle school fade quickly, I find significant positive effects on the likelihood of taking college credit-bearing courses in high school, college enrollment, enrolling in more selective colleges, persistence in college, and degree attainment.

We use statewide administrative data from Missouri to document the prevalence of Industry Recognized Credential (IRC) programs in public high schools and understand the characteristics of students who complete IRCs. We show that 9 percent of Missouri students complete an IRC during their senior year of high school. IRC completers have lower achievement and are more likely to be disadvantaged along several measurable dimensions relative to their peers who complete analog college-ready programs, on average. Noting these average relationships, there is substantial heterogeneity among individual IRCs in terms of the types of students served: some IRCs attract students with high test scores who mostly go on to attend college, whereas others serve low-scoring students who mostly forego college. There is strong gender segregation across individual IRCs that aligns with gender segregation across occupations in the labor market.

What does it mean for students to be in a gifted program? While about 7% of students nationally participate in gifted programs, relatively little is known about the experiences of students in these programs or how they vary across districts. Combining administrative and survey data, we describe the structure of gifted programs across nearly 300 school districts in Washington State. Using covariate adjustments and student fixed effects, we find that participation in gifted programs increases access to advanced courses, high-achieving peers, smaller classrooms, and more qualified teachers. These effects are largely concentrated in larger urban and suburban school districts that frequently run large, self-contained gifted programs. Effects of participation are much smaller for small school districts, rural or town school districts, and districts with small gifted programs. While gifted participation changes the educational environment for the average student in the state, the median school district program effect is near zero across the measures of educational environments we consider. This divergence is driven by a pattern of large school districts, high-income school districts, and urban and suburban school districts having programs with significantly larger effects on learning environments. Finally, we find that gifted program effects are larger for some student subgroups, but this is entirely due to district treatment effect heterogeneity, not differential effects on subgroups within districts.

There is empirical evidence of substantial heterogeneity in economic mobility across geographic areas and the efficacy of schools has been suggested as an explanatory factor. Using administrative microdata from seven states covering nearly 3 million students, we explore the potential role of schools in promoting economic mobility by estimating cross-district variation in “academic mobility”—a term we use to describe the extent to which students’ ranks in the distribution of academic performance change during their schooling careers. We show that there exists considerable heterogeneity in academic mobility across school districts. However, after aggregating our district-level measures of academic mobility to the commuting-zone level and merging them with geographically matched external estimates of economic mobility, we find little scope for geographic differences in academic mobility to meaningfully account for differences in economic mobility.

A number of school districts and states have implemented transition intervention programs designed to help high school students graduate ready for college. This study estimates the effectiveness of a transition program implemented statewide in Kentucky for high school seniors called Targeted Interventions (TI). Using 11 years of linked panel data, this study tracks the college progression of seven cohorts of students as they move from high school into college. Using a difference-in-regression discontinuity design, we estimate the program’s impact on college credit attainment and transfer as well as the extent to which the program has helped reshape pathways through college. We find that the TI program significantly increased the likelihood that students would take at least 15 credits during the first term in college, a key measure that has been shown to be predictive of college completion. These early effects, however, do not translate into statistically significant impacts on the likelihood of transfers from a 2-year to a 4-year college, or the likelihood of earning enough credits to graduate from college. We discuss some possible explanations for why the TI program did not lead to observable improvements in college transfer or credit accumulation.

Testing students and using test information to hold schools and, in some cases, teachers accountable for student achievement has arguably been the primary national strategy for school improvement over the past decade and a half. Tests are also used for diagnostic purposes, such as to predict students at-risk of dropping out of high school. But there is policy debate about the efficacy of this usage, in part because of disagreements about whether tests are an important schooling outcome. We use panel data from three states – North Carolina, Massachusetts and Washington State – to investigate how accurate early test scores are in predicting later high school outcomes: 10th grade test achievement, the probability of taking advanced math courses in high school, and graduation. We find 3rd grade tests predict all of these outcomes with a high degree of accuracy and relatively little diminishment from using 8th grade tests. We also find evidence that using a two-stage model estimated on separate cohorts (one predicting 8th grade information using 3rd grade information, and another predicting high school outcomes with 8th grade information) only slightly diminishes forecast accuracy. Finally, the use of machine learning techniques increases accuracy of predictions over widely used linear models, but only marginally.

In this paper we use data from two states—Michigan and Washington—on COVID case rates at the county level linked to information on the type of instructional modality offered by local public school districts to assess the relationship between modality and COVID outcomes. We focus primarily on COVID case rates, but also provide estimates for hospitalizations (in Washington only) and deaths. Our preferred district and month fixed effects models exploit within district (over time) variation in instructional modality and account for time-invariant district factors. In both states, we find evidence that instructional modality does lead to increases in COVID spread in communities with moderate to high levels of pre-existing COVID cases, although the causal effect is small in magnitude.

A growing quantitative literature finds evidence that student teaching placements predict later outcomes of teacher candidates and their students, but there is little large-scale quantitative evidence about the mechanisms for these estimated relationships. We use data from a survey of STEM teachers in Washington State to better understand how their perceptions of preparation are related to student teaching placements and current classroom environment. We find evidence that the composition of students in student teaching classrooms are predictive of STEM teachers’ perceptions of their preparation. For example, STEM teachers who student taught in classrooms with more English Language Learners and economically disadvantaged students reported feeling prepared to teach these specific student populations. Likewise, STEM teachers who student taught in high-poverty classrooms tended to report feeling better prepared to manage their current classroom, particularly if they were currently teaching in a high-poverty classroom.

Students’ performance on standardized tests is clearly predictive of their later outcomes (Goldhaber & Özek, 2019) but whether the costs of administering tests are justified by the value of the tests for improving students’ outcomes is controversial. This controversy fuels heated debates over federal testing requirements, such as those instituted under No Child Left Behind (NCLB) and continued under the Every Student Succeeds Act (ESSA). All ESSA-required tests were canceled in the 2019-20 school year due to COVID-19, and there was significant political debate about whether they ought to be required in 2020-21. Ultimately the U.S. Department of Education (USDOE) allowed for some testing flexibility in the form of ESSA waivers.
In this policy brief, we outline some of the common ways states might use tests to improve student outcomes and the implications of requested and approved waivers on these uses. In particular, we highlight features of waiver requests that are especially important if tests are to be used by specific actors (e.g., families) to benefit students in specific ways. We conclude with a discussion of how testing policy needs to be designed if statewide tests are going to both be useful and maintain political support.

We used survey and administrative data from Washington State to assess the degree to which special education teacher preparation, district literacy instructional practices, and the alignment between preparation and practice were associated with the reading test score gains of students with high-incidence disabilities taught by early-career special education teachers in grades 4-8. These students tended to have larger reading gains when their district emphasized evidence-based literacy decoding practices (e.g., phonological awareness, phonics, and reading fluency) and when their special education teacher graduated from a teacher education program that also emphasized these practices. Students with high-incidence disabilities in districts that emphasized balanced literacy practices tended to have lower reading gains. Finally, students with high-incidence disabilities taught by early-career special education teachers tended to have larger reading gains when their teacher’s student teaching placement was supervised by a more experienced cooperating teacher.

Free and reduced-price meal eligibility (FRM) is commonly used in education research and policy applications as an indicator of student poverty. However, using multiple data sources external to the school system, we show that FRM status is a poor proxy for poverty, with eligibility rates far exceeding what would be expected based on stated income thresholds for program participation. This is true even without accounting for community eligibility for free meals, although community eligibility has exacerbated the problem in recent years. Over the course of showing the limitations of using FRM data to measure poverty, we provide promising validity evidence for a new, publicly-available measure of school poverty based on local-area family incomes.

We use comprehensive administrative data from three states to document the relationships between geographic mobility and student outcomes during K-12 schooling. We focus specifically on nonstructural mobility events—which we define as school or district changes that do not occur naturally as the result of planned transitions between schools—and on longitudinal measures that capture these events cumulatively for students. We show that the number of nonstructural moves experienced by a student is a powerful indicator of low academic performance and graduation rates. Longitudinal information on student mobility is unlikely to be readily available to local practitioners—i.e., individual districts, schools, or teachers. However, due to recent investments in longitudinal data systems in most states, this information can be made available at low cost by state education agencies.

We use data on over 14,000 teacher candidates in Washington state, merged with employment data from the state’s public schools and Unemployment Insurance system, to investigate the career paths and earnings of teacher candidates in the state. Around 75% of candidates are employed in some education position in each of the 5 years after student teaching, but we find considerable movement from education positions outside of public schools into public school teaching positions in the first few years after candidates complete student teaching. Candidates with STEM endorsements and candidates who graduated after the Great Recession are disproportionately likely to be employed in public K–12 teaching positions compared with other education positions. Finally, candidates employed in K–12 public schools earn considerably more on average than candidates employed outside of public schools, but due to the considerable compression of teacher salaries, many candidates who do not enter teaching—particularly candidates with STEM endorsements—earn more than they would have in K–12 public schools.
