Postsecondary educators have expressed concerns for many years about how prepared high school students are for college. As a result, states and organizations have launched a variety of initiatives designed to increase high school students' readiness for college, including increased access to college-level courses. One of the most promising initiatives has been the early college high school model--an innovative high school-college blend that is purposefully designed to ensure that students are ready for college. Early colleges, as they are often called, expand the model of dual enrollment by incorporating dual enrollment courses into the whole structure of the school. This article presents an overview of early colleges and their results, focusing particularly on how early colleges support the goal of college readiness. The first section briefly explores the concept of college readiness. The second section describes the early college high school model, and the final section highlights the impact of the model on different indicators of college readiness. (Contains 1 figure.)
