The Early College Initiative (ECI) high schools in New York City provide opportunities to take college-credit courses up to the equivalent of an associate's degree while in high school. In this study, we measure the association between attending an ECI high school and college persistence. Our sample is the 3,271 students who graduated from New York City public high schools in the ECI network between Fall 2006 and Fall 2013 and enrolled in college. We use survival analysis to measure the relationship between demographic, academic, and behavioral risk factors and persistence of ECI graduates. We find that Black and Latinx students are as likely as White students to persist, when both high school achievement and behavioral factors, such as attendance, are taken into account. Differences in persistence do exist by gender with young women more likely to persist when compared with young men. This study provides empirical evidence that attending early college high schools has the potential to narrow racial and ethnic gaps in postsecondary outcomes.
