Inconsistent reporting of critical facets of classroom interventions and their related impact evaluations hinders the field’s ability to describe and synthesize the existing evidence base. In this essay, we present a set of reporting guidelines intended to steer authors of classroom intervention studies toward providing more systematic reporting of key intervention features and setting-level factors that may affect interventions’ success. The guidelines were iteratively developed using recommendations and feedback from scholars active in conducting and synthesizing classroom intervention research. This effort aims to open wider the ‘black box’ in classroom research, communicating key information with more precision and detail to practitioners and future researchers, and permitting the field to more efficiently accumulate and synthesize findings on classroom interventions, determining what works, for whom, and under what conditions.

This paper reports findings from a nationally representative survey of K-12 teachers in May 2023 that examines the potential long-term impacts of COVID-19 on public schooling. The findings suggest fundamental ways in which school operations, instructional practice and parent-teacher interaction have changed since the pandemic. Some changes seem promising; others suggest caution. While policymakers may not be able to directly influence some of the reported changes in the short run, monitoring the evolution of school practices (and their consequences for children) will position educational leaders to help teachers and students address the consequences of the COVID-19 pandemic going forward.

The immediate impacts of COVID-19 on K12 schooling are well known. Over nearly 18 months, students’ academic performance and mental health deteriorated dramatically. This study aims to identify if and how the pandemic led to longer-term changes in core aspects of schooling. Drawing on semi-structured interviews with 31 teachers and administrators across 12 districts in two states, we find that schools today look quite different in several areas including the availability and use of instructional technology, instructional practice, parent-teacher communication, and the balance between academics and social-emotional well-being. We interpret these findings through the lens of institutional theory, and discuss implications of the changes for practitioners and policymakers.

In the context of an ongoing national conversation about teacher shortages, we build on prior literature on the efficacy of teacher certification pathways by comparing entry and exit patterns based on age at the time of certification. All trainees who complete a state certification process have invested substantial time and resources into entering teaching. Competing employment opportunities and expectations might vary with age. We use both linear regression and discrete-time hazard models to examine employment and subsequent exit of newly certified teacher trainees in Michigan from 2011 to 2023. We find that while mid-career entrants in their 30s and 40s compose a small share of new certificates, they are more likely to enter a teaching position and no more likely to subsequently exit than counterparts who were certified in their early 20s. Mid-career pathways also contribute to teacher diversity by attracting more Black and male teachers who enter and persist.

Specialized high schools are an increasingly popular way to prepare young adults for postsecondary experiences and expand school choice. While much literature ex- amines charter school spillover effects and the effects of specialized schools on the students who attend them, little is known about the spillover effects of specialized high schools on traditional public schools (TPS). Using an event study design, we show that one type of specialized high school, North Carolina’s Cooperative Innovative High Schools, initially attracted students who were higher achieving and more likely to be white than TPS students, but these specialized schools became more representative of the district population over time. On average, the opening of specialized schools had a mix of null and positive spillover effects on TPS student achievement. While there is some evidence of negative spillovers from the first schools that opened, the effects become more positive over time.

Targeted school funding is a potentially valuable policy lever to increase educational equality by race, ethnicity, and income, but it remains unclear how to target funds most effectively. We use a regression discontinuity approach to compare districts that narrowly passed or failed a school funding election. We use close tax elections in 9 states to identify effects of operating funds and close bond elections in 8 states to identify effects of capital funds. Results indicate positive achievement returns to spending, especially for math achievement and for operating funds. We find similar returns to spending by race, ethnicity, and income (not statistically different), but we find significantly larger returns for students in low-resource districts than in high-resource districts, including larger returns for Black, Latinx, and low-income students. Mediation analyses suggest spending on teacher salaries and counselors may be particularly effective mechanisms to increase achievement among Black and low-income students.

This study uses a concurrent embedded mixed-methods design to assess the impact of additional funding on student outcomes in a large, urban school district in the Southeastern United States. The district implemented student-based budgeting (SBB), which allocates dollars to schools based on student characteristics using a weighted student funding (WSF) formula and provides flexibility to principals to allocate those dollars under site-based budgeting. Using simulated instruments in a difference-in-differences framework, we estimate the impact of additional funding on student outcomes provided by WSF. Student test scores in math and ELA increased by 0.14 and 0.12 standard deviations, respectively. Our qualitative analysis suggests that the flexibility given to principals was a key mechanism that improved student outcomes.

The United States is facing growing teacher shortages that may disproportionately affecting schools serving high proportions of students of color, low-income students, and those in rural or urban areas. Special education teachers (SETs) are particularly in demand. Each year, nearly half of all vacancies are filled with teachers switching from one school to another, yet little research has addressed the nuances of within-career sorting, especially by subject. Utilizing longitudinal data covering 27 years and over 1.2 million teachers in Texas, this study examines SET switching patterns relative to core subject teachers, utilizing discrete time hazard modeling, fixed-effect regressions, and geographic information system mapping. Results show SETs switch schools at much higher rates, associated with experience, salary, and student demographics, yet generally transfer shorter distances than their peers. These findings highlight differential subject-specific labor market dynamics, suggesting targeted recruitment and retention strategies to address widespread shortages.

Currently 15 percent of U.S. students receive special education services, a widespread intensive intervention with variable effects on students. Spurred by changes in federal policy, many states and districts have begun adopting the Response to Intervention (RTI) approach to identifying students to receive special education services. RTI seeks to provide a system for targeting interventions to children facing early academic challenges and identifying children with specific learning disabilities (SLD). This paper uses a difference-in-differences design to examine the effects of RTI adoption across Oregon on elementary students’ disability identification and state-standardized achievement test scores. RTI adoption reduced special education identification by 1.4 percentage points (11%) and SLD identification by 0.5 percentage points (15%). RTI also caused moderately large reading test score gains for Black students (0.15 SD) and did not reduce other students’ achievement. These findings suggest RTI is a promising approach to supporting struggling students.

This study uses administrative data from Oregon to estimate the extent to which base salary increases reduce teacher turnover and to investigate whether these effects are heterogeneous by teacher characteristics. Using multiple sets of fixed effects to isolate plausibly exogenous variation in salaries across experience bands within a district, we find that increases in salary are associated with decreases in teacher turnover. In our fully specified model, we estimate that a 1 percent increase in current and future base salary is associated with a 0.15 percentage point decline in turnover. This relationship appears to attenuate for mid-career teachers. While increasing salary reduces turnover among BA and MA degree teachers, these effects are not statistically different from each other. We also find that teachers in special education positions are more responsive to salary increases than those only assigned general education classes. Together, our results indicate the varied impact salaries may have in ameliorating teacher staffing challenges across different teacher characteristics.
