This article describes our efforts to screen and enrol clinical trial participants conscientiously in the COVID-19 pandemic setting. We present the standard screening and enrolment process prior to, and our process of adapting to, the pandemic. Our goal was to develop a way to screen and enrol people for clinical trials that was both equitable and…

This article synthesizes findings from a reanalysis of data from the Head Start Impact Study with a focus on impact variation. This study addressed whether the size of Head Start's impacts on children's access to center-based and high-quality care and their school readiness skills varied by child characteristics, geographic location, and the…

Well-established evidence of the ill-effects of exclusionary school discipline, its disproportionate use on students of colour, and association with the "school-to-prison pipeline" has, in the last decade, led to systemic reforms in the United States, which are successfully reducing exclusion and improving outcomes. Few studies, however,…

The Center for Education Policy Research at Harvard University explained, "Across the country, 10- 40% of seemingly college-intending students, particularly those from low-income backgrounds, fail to enroll in college the fall after graduation. This phenomenon is known as "summer melt" (Castleman, Page, and Snowdon, 2013). In order…

Attending high-quality early childhood care and education (ECCE) is associated with higher cognitive and social-emotional skills, especially for children growing up in poverty, but access to high-quality ECCE is limited. This study capitalizes on the random assignment design of the Head Start Impact Study to better understand whether the…

Despite growing economic opportunities in "middle-skills" science, technology, engineering, and mathematics (STEM) professions, the majority of community college STEM students leaves the STEM pipeline or withdraws from college altogether. We tested an intervention that addressed one reason why students abandon STEM: psychosocial…

Large numbers of qualified students do not apply to and enroll in college. Yet, earning a college degree is one of the primary pathways for economic success and is increasingly required for good jobs and high wages. A number of programs and practices aim to improve college readiness and enrollment, including "Take Stock in Children's®…

In the summer of 2013, the National Council on Teacher Quality (NCTQ) issued public, highly-visible ratings of teacher education programs as part of their ambitious and controversial Teacher Prep Review. We provide the first empirical examination of NCTQ ratings, beginning with a descriptive overview of the ratings and documentation of how they…

This paper evaluates the effects of a high school curriculum reform on students' probability to enroll at university and to choose a Science, Technology, Engineering or Mathematics (STEM) major. The reform increased the difficulty of graduating from high school by increasing the instruction time in core subjects and by raising the graduation…

When nonrandom treatments occur across sites, within-site matching (WM) is often desirable. This approach, however, can significantly reduce treatment group sample size and exclude substantively important subgroups. To limit these drawbacks, we extend a matching approach developed by Stuart and Rubin to a multisite study. We demonstrate the…

This paper estimates the effect of tuition fees on enrolment behaviour among prospective students in Germany. According to the rational choice theory (RCT), we argue that due to the higher costs brought on by such fees tuition fees should have a negative effect on student's enrolment. This should be even more pronounced among prospective students…

In some educational settings, the cost of textbooks approaches or even exceeds the cost of tuition. Given limited resources, it is important to better understand the impacts of free open educational resources (OER) on student outcomes. Utilizing digital resources such as OER can substantially reduce costs for students. The purpose of this study…

The purpose of this study was to conduct a rigorous examination of co-enrollment of students in math remediation and college-level math. A quasi-experimental, posthoc design examined the outcomes and the relationships of two groups of students who participated in a pilot project the goal of which was to assess the co-enrolled model that is…

School attendance is a robust predictor of course performance, and it is consistently the strongest predictor of high school dropout, even more so than suspensions and test scores. Focusing on getting students to school is an essential part of decreasing high school dropout rates. What is concerning is that up to 20% of students miss essentially a…

This study is a randomized controlled trial that assessed the impact of Early College High Schools on students' high school graduation, college enrollment, and college degree attainment, as well as students' high school experiences using extant data and survey data. The study included 10 Early Colleges that enrolled students in Grades 9 to 12 in…
