Expanding pathways from high school to higher education is essential for Colorado to reach its goals of increasing college completion rates, erasing attainment gaps and increasing high school student engagement. Colorado, like other states across the country, utilizes dual enrollment as a strategy to cultivate seamless P-20 pathways and increase credential completion. Dual enrollment programs provide high school students with the opportunity to enroll in college-level courses, simultaneously earning both high school and college credit, often at greatly reduced costs. These programs help students develop the knowledge, skills and abilities necessary to be postsecondary education- and workforce-ready. Research indicates that dual enrollment students are more likely to enroll and persist in college and are less likely to need remedial education once in college. The Colorado Department of Higher Education (CDHE) and the Colorado Department of Education (CDE) have prepared this report pursuant to statute (C.R.S. §22-35-112). The data, collected through the CDHE Student Unit Record Data System (SURDS) unless noted otherwise, provide a descriptive summary of students in Colorado's public education system who participated in dual enrollment programs in the 2017-2018 Academic Year.
