Public policies targeting individuals based on need often impose disproportionate burden on communities that lack the resources to implement these policies effectively. In an elementary school setting, I examine whether community-level interventions focusing on similar needs and providing resources to build capacity in these communities could improve outcomes by improving the effectiveness of individual-level interventions. I find that the extended school day policy that targets lowest-performing schools in reading in Florida significantly improved the effectiveness of the third-grade retention policy in these schools. These complementarities were large enough to close the gap in retention effects between targeted and higher-performing schools.

Black teachers are critical resources for our children and schools. Pairing experimental data with rich measures of teacher mindsets and practices and varied student outcomes, I document that: (1) Black teachers in upper-elementary grades have large effects on the self-efficacy and classroom engagement of their Black students (0.7 and 0.8 SD) but not for non-Black students, potentially driven by role modeling; (2) race-matching effects on Black students’ social-emotional learning explain a moderate to large share of effects on more distal outcomes, including absences and test scores; (3) Black teachers also benefit the test scores (0.2 SD) and absences (roughly 20% decrease) of all students—no matter their race/ethnicity—that often persist many years later into high school; and (4) in addition to potential role-modeling channels, Black teachers bring unique mindsets and practices to their work (e.g., preparation for and differentiated instruction, growth mindset beliefs, well-organized classrooms) that mediate a moderate to large share of their effects on student outcomes. These findings help bridge the quantitative “teacher like me” literature with theoretical discussion and qualitative exploration on why Black teachers matter.

Many school districts consider family preferences in allocating students to schools. In theory, this approach provides traditionally disadvantaged families greater access to high-quality schools by weakening the link between residential location and school assignment. We leverage data on the school choices made by over 233,000 New York City families to examine the extent to which the city’s school choice system fulfills this promise. We find that over-subscribed and high-quality schools enroll smaller proportions of students from traditionally disadvantaged families. We explore three mechanisms to explain this inequitable distribution: application timing, neighborhood stratification, and the architecture of the choice process itself. We find that all three mechanisms have a disequalizing influence and propose several policy shifts to address this inequality.

Educational researchers often report effect sizes in standard deviation units (SD), but SD effects are hard to interpret. Effects are easier to interpret in percentile points, but converting SDs to percentile points involves a calculation that is not transparent to educational stakeholders. We show that if the outcome variable is normally distributed, we can approximate the percentile-point effect simply by multiplying the SD effect by 37 (or, equivalently, dividing the SD effect by 0.027). For students in the middle three-fifths of a normal distribution, this rule of thumb is always accurate to within 1.6 percentile points for effect sizes of up to 0.8 SD. Two examples show that the rule can be just as accurate for empirical effects from real studies. Applying the rule to empirical benchmarks, we find that the least effective third of educational interventions raise scores by 0 to 2 percentile points; the middle third raise scores by 2 to 7 percentile points; and the most effective third raise scores by more than 7 percentile points.

High-impact tutoring has emerged as a primary school district investment for addressing learning loss that occurred during the COVID-19 pandemic. While existing research shows that high-impact tutoring is effective for accelerating student learning, this study examined the school-level facilitators and barriers to scaling high-impact tutoring. Situated in an urban traditional school district and an urban charter management organization, we collected survey and interview data from teachers and administrators to identify scaling challenges. Major barriers to scaling included time and space constraints, tutor supply and quality, updated data systems, and school level costs, while a key facilitator was teacher buy-in. We end the paper with recommendations for how districts can strategically grow their high-impact tutoring efforts.

What happens to public opinion when prominent partisan officials intervene in education policy debates? We analyzed the results of 18 survey experiments conducted between 2009 and 2021 with nationally representative samples of U.S. adults. Each experiment explored the effect of an endorsement of a specific education policy by a high-profile partisan official on the public’s attitudes toward that policy. Our results indicated that the engagement of such officials in education policy issues typically did little to move public opinion in the direction of the cue-giver’s preferred policies. Instead, the chief consequence was increased polarization among the public along partisan lines. A key exception applied to endorsements of policies that diverged from the traditional position of the cue-giver’s own party, which tended to shift aggregate public opinion modestly in favor of those policies. Such cross-party cues also had minor de-polarizing consequences.

We analyzed the proposed spending data for the American Recovery Plan’s Elementary and Secondary Emergency Relief III (ESSER III) fund from the spring of 2021 of nearly 3,000 traditional public-school districts in the United States to (1) identify trends in the strategies adopted and (2) to test whether spending strategies were observably heterogeneous across district characteristics. We found that districts proposed a breadth of spending patterns with ESSER III. Moreover, there was a clear prioritization on spending related to academic learning recovery and facilities and operations spending, with the latter being particularly emphasized in higher-poverty districts. This divergent spending pattern may have important equity implications for short-term academic learning recovery for students affected by the COVID-19 pandemic.

This mixed-methods study synthesizes Standards-Based Grading (SBG) literature, analyzes 249 Arkansas administrators' survey responses using OLS regressions, and identifies themes through in-vivo coding of qualitative feedback. Results show more SBG support among liberal, elementary-level administrators in larger, economically diverse districts. Qualitative insights highlight structural barriers and mindsets against SBG, emphasizing its importance for mastery-focused assessment and grading alignment. These findings underscore the influence of principals' beliefs on SBG support and suggest researching the contextual and ideological factors influencing SBG's implementation.

We examine the fundamental and complex role that time plays in the learning process. We begin by developing a conceptual framework to elucidate the multiple obstacles schools face in converting total time in school into active learning time. We then synthesize the causal research and document a clear positive effect of time on student achievement of small to medium magnitude, but also with likely diminishing marginal returns. Further descriptive analyses reveal how large differences in the length of the school day and year across public schools are an underappreciated dimension of educational inequality in the United States. Finally, our case study of time loss in one urban district demonstrates the potential to substantially increase learning time within existing constraints.

Federal incentives and requirements under the Obama administration spurred states to adopt major reforms to their teacher evaluation systems. We examine the effects of these reforms on student achievement and attainment at a national scale by exploiting their staggered implementation across states. We find precisely estimated null effects, on average, that rule out impacts as small as 0.017 standard deviations for achievement and 1.2 percentage points for high school graduation and college enrollment. We highlight five factors that likely limited the efficacy of teacher evaluation at scale: political opposition, decentralization, capacity constraints, limited generalizability, and the absence of compensating wages.
