The University of Texas at Austin's OnRamps dual-enrollment initiative aims to increase the number and diversity of students who are fully prepared to follow a path to college and career success. Supported by the Texas Legislature, OnRamps provides high school students access to eleven UT Austin courses, developed and delivered by UT Austin faculty, that can be applied to the Texas Core Curriculum. The purpose of this study was two-fold: to descriptively examine the college enrollment of OnRamps students and to estimate the impact of OnRamps on college enrollment using a comparison group of non-OnRamps students. The results show that the vast majority of OnRamps students go on to postsecondary education and they are more likely to do so compared to their peers when controlling for a wide range of demographic and academic characteristics and the schools students attended.
