Policymakers' solutions to the problem of inequitable access to postsecondary institutions often focus on the financial barriers students face. However, other barriers are just as significant. Students may face barriers in the logistical aspect of applying to college. They may not have the knowledge and skills they need to succeed in college…

Estimating treatment effects for subgroups defined by posttreatment behavior (i.e., estimating causal effects in a principal stratification framework) can be technically challenging and heavily reliant on strong assumptions. We investigate an alternative path: using bounds to identify ranges of possible effects that are consistent with the data.…

Early Colleges (ECs) provide high school students access to college coursework with the goal of increasing postsecondary opportunities for traditionally underrepresented students. We examine the impact of ECs on postsecondary attainment, calculate the resulting monetary benefits, and then estimate the per-student costs of ECs compared to…

Early colleges are an innovative model of schooling that combines high school and college. A 14-year, rigorous experimental study has been examining whether this model works. The study compares early college students who were accepted through a lottery to students who applied to early colleges but were not accepted through the lottery (the control…

Advancing in key courses in ninth grade is an early, crucial step in preparing for college. Students who miss academic targets early in high school may not be ready to go to college 4 years later. In the United States, when students fail key courses in ninth grade, they may struggle to catch up to their peers who successfully took and passed these…

Developed in response to concerns that too few students were enrolling and succeeding in postsecondary education, early college high schools are small schools that blur the line between high school and college. This article presents results from a longitudinal experimental study comparing outcomes for students accepted to an early college through…

Building on a previous randomized experiment of the impact of Early Colleges (ECs) (Berger et al., 2013), this follow-up study assessed longer-term impacts of ECs on students' postsecondary outcomes 6 years after expected high school graduation. It also explored the extent to which students' high school experiences mediate EC impacts.…

Early colleges are a new model of schooling in which the high school and college experiences are merged, shortening the total amount of time a student spends in school. This study uses a lottery-based experimental design to examine the impact of the model on longer term outcomes, including attainment of a postsecondary credential and academic…

To increase the number of students graduating from high school prepared for college, North Carolina has established the largest number of Early College High Schools (ECHS) in the United States. Early results from a rigorous, independent study of North Carolina's initiative have shown that these schools have substantial positive impacts on student…

This article utilizes mixed methods--a lottery-based experimental design supplemented by qualitative data--to examine college readiness within an innovative high school setting: early college high schools. Early colleges are small schools that merge the high school and college experiences and are targeted at students underrepresented in college.…

Developed in response to concerns that too few students were enrolling and succeeding in postsecondary education, early college high schools are small schools that blur the line between high school and college. This article presents results from a longitudinal experimental study comparing outcomes for students accepted to an early college through…

Background: Early college high schools, small schools that blur the line between high school and college, have been obtaining very strong results. This paper uses the frame of student engagement to posit an explanation for the success of these schools. Purpose: This paper examines the impact of early college high schools on indicators and…

As implemented in North Carolina, Early College High Schools are small, autonomous schools designed to increase the number of students who graduate from high school and are prepared for postsecondary education. Targeted at students who are underrepresented in college, these schools are most frequently located on college campuses and are intended…

Early college high schools are a new and rapidly spreading model that merges the high school and college experiences and that is designed to increase the number of students who graduate from high school and enroll and succeed in postsecondary education. This article presents results from a federally funded experimental study of the impact of the…
