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 early college model on Grade 9 outcomes. Results show that, as compared to control group students, a statistically significant and substantively higher proportion of treatment group students are taking core college preparatory courses and succeeding in them. Students in the treatment group also have statistically significantly higher attendance and lower suspension rates than students in the control group.
