Middle school transitions are increasingly required, despite documented negative effects on general education students (GENs). We explore if and how the move to middle school differentially affects students with disabilities (SWDs), a large and low-performing group of students. Using an instrumental variables strategy and NYC data on nine cohorts of students, we find the middle school transition causes a 0.29 standard deviation decline in SWD math performance, a 0.16 standard deviation decline in ELA performance, and a one percentage point increase in grade retention. However, after accounting for potential mediators (e.g. peer cohort stability) effects are similar for SWDs and GENs, suggesting the need to ease the middle school transition for all students.

Tutoring has emerged as an especially promising strategy for supporting students academically. This study synthesizes 33 articles on the implementation of tutoring, defined as one-to-one or small-group instruction in which a human tutor supports students grades K-12 in an academic subject, to better understand the facilitators and barriers to program success. We find that policies influenced tutoring implementation through the allocation of federal funding and stipulation of program design. Tutoring program launch has often been facilitated by strategic relationships between schools and external tutoring providers and strengthened by transparent assessments of program quality and effectiveness. Successful implementation hinged on the support of school leaders with the power to direct school funding, space, and time. Tutoring setting and schedule, recruitment and training, and curriculum influenced whether students are able to access quality tutoring and instruction. Ultimately, evidence suggests that tutoring was most meaningful when tutors fostered positive student-tutor relationships which they drew upon to target instruction toward students’ strengths and needs.

There has been an explosion of research on racial disproportionality in special education. Some recent research shifts the focus from the role of student characteristics alone to inquire whether school context moderates findings (e.g., is a Black student less likely than a White student to receive special education services as the proportion of a school’s Black students increases?). We significantly extend this emerging literature using eight years of elementary student-and school-level data from NYC public schools, examining more school contextual moderators, expanding racial categories, and distinguishing between cross-sectional and over-time differences. We find many more moderators than previous research has identified and these school context factors appear to be particularly salient for the classification of Black students.

The number of English learners enrolled in public schools has grown substantially in the United States over the past two decades. The growth is especially large in states in the South and Midwest that have not been traditional destinations for recent immigrants. In this study, we examine the effects of an influx of new English learners on students in receiving schools in Delaware, which is one of the so-called “new destination” states. We find significant positive spillover effects in the short term of new English learners on the test scores of the other students in the receiving schools. The positive effects are mainly concentrated among current and former English learners.

This mixed methods research study explores superintendents’ beliefs about and engagement in state education policymaking processes. Through interviews with 58 superintendents and a national survey of superintendents, I find that many superintendents feel that their voices have value in state policymaking spaces; however, superintendents’ actual engagement in state policymaking processes is relatively low. Three factors shape superintendents’ state policy engagement: (1) personal capacity, (2) proximity to state capitol, and (3) district size. This work can guide the development of formal educational opportunities and experiences to better prepare superintendents to engage in policy spaces. Colleges of education, researchers, and policymakers can also draw on this work as they consider solutions to reduce inequalities in superintendents’ access to shape state education policy.

School climate is critical to school effectiveness, but there is limited large-scale data available to examine the magnitude and nature of the relationship between school climate and school improvement. Drawing on statewide administrative data linked with unique teacher survey data in Michigan, we examine whether school climate appeared to play a role in the effects of a state-level school turnaround intervention. Using comparative interrupted time series models and descriptive mediation analysis, we find that students in schools with more positive school climate appeared to fare better than their peers in schools with less positive climate. Certain elements of climate—relational trust and school leadership—also mediated the effect of turnaround on student achievement. Our findings have implications for school improvement planning, for the design of evaluations of school turnaround initiatives, and for data collection by states aiming to improve their lowest performing schools.

The Core Knowledge curriculum is a K-8 curriculum focused on building students General Knowledge about the world they live in that is hypothesized to increase reading comprehension and Reading/English-LA achievement. This study utilizes an experimental design to evaluate the long term effects of attending Charter schools teaching the Core Knowledge curriculum. Fourteen oversubscribed kindergarten lotteries for enrollment in nine Core Knowledge Charter schools using the curriculum had 2310 students applying from parents in predominately middle/high income school districts. State achievement data was collected at 3rd- 6th grade in Reading/English-LA and Mathematics and at 5th Grade in Science. A new methodology addresses two previously undiscovered sources of bias inherent in kindergarten lotteries that include middle/high income families. The unbiased confirmatory Reading-English-LA results show statistically significant ITT (0.241***) and TOT (0.473***) effects for 3rd-6th grade achievement with statistically significant ITT and TOT effects at each grade. Exploratory analyses also showed significant ITT (0.15*) and TOT (0.300*) unbiased effects at 5th grade in Science. A CK-Charter school in a low income school district also had statistically significant, moderate to large unbiased ITT and TOT effects in English Language Arts (ITT= 0.944**; TOT = 1.299**), Mathematics (ITT= 0.735*; TOT = 0.997*) and positive, but insignificant Science effects (ITT= 0.468; TOT = 0.622) that eliminated achievement gaps in all subjects.

In this study, we examine an at-scale effort to encourage the formation of career pathways in California, with the goal of estimating the initiative’s causal effects on community college enrollment. We leverage a discontinuous assignment rule used to award grant funds to obtain credibly causal estimates of an ambitious $500 million effort to expand and establish career and technical education pathways between K-12 and community colleges. The competitive grant application process used a standardized rubric, and those receiving a score above a predetermined threshold were awarded funding (i.e., treatment group) while those just below received no funding (i.e., control group), allowing for a regression discontinuity (RD) design. We found that successful grantees did not experience overall enrollment increases in postsecondary partnerships; however, there were enrollment increases of 13.5 percent to 14.8 percent in CTE health sector courses, the program targeted the most for expansion. Manufacturing, and information communication technology, the other programs with the most expanded offerings, experienced no increases in postsecondary enrollment. The enrollment increases for the health sector were concentrated amongst female students in line with earlier findings by Bonilla (2020) documenting reductions in high school dropout rates for female students. These findings suggest that partnerships between K-12 schools and postsecondary institutions may be a viable avenue for increasing alignment between enrollment and high- growth sectors.

Stagnating teacher salaries and the widening gap between public school teachers and similar workers have led to growing concerns that teachers will seek out additional employment—possibly impacting their instructional practice in the process. Using data from the Schools and Staffing Survey and the National Teacher and Principal Survey from 1994–2021, we show that teacher multiple jobholding has been remarkably stable over time. When examining the predictors of multiple jobholding, we find a high degree of variation across the timing, focus, and setting of teachers’ additional work. Using regression analysis, we show that teachers who work an additional job have lower turnover rates, with the exception of teachers who work outside of school, who leave teaching at higher rates.

Four-day school weeks are becoming increasingly common in the United States, but their effect on students’ achievement is not well-understood. The small body of existing research suggests the four-day schedule has relatively small, negative average effects (~-0.02 to -0.09 SD) on annual, standardized state test scores in math and reading, but these studies include only a single state or are limited by using district-level data. We conduct the first multi-state, student-level analysis that estimates the effect of four-day school weeks on student achievement and a more proximal measure of within-year growth using NWEA MAP Growth assessment data. We conduct difference-in-differences analyses to estimate the effect of attending a four-day week school relative to attending a five-day week school. We estimate significant negative effects of the schedule on spring reading achievement (-0.07 SD) and fall-to-spring achievement gains in math and reading (-0.06 SD in both). The negative effects of the schedule are disproportionately larger in non-rural schools than rural schools and for female students, and they may grow over time. Policymakers and practitioners will need to weigh the policy’s demonstrated negative average effects on achievement in their decisions regarding how and if to implement a four-day week.
