Earning a postsecondary credential is increasingly important for individuals, the economy, and the future of Colorado. The Georgetown Center for Education and the Workforce predicts that in the modern economy, two-thirds of entry-level jobs will require training beyond high school. In response to these realities, the Colorado Department of Higher Education (CDHE) and the Colorado Commission on Higher Education (CCHE) released a statewide plan to help Colorado reach 66 percent educational attainment among adults by 2025. To get there, the master plan lays out four strategic goals: increase credential completion, erase equity gaps, improve student success, and invest in affordability and innovation. Developing Colorado's own population by ensuring high school graduates are enrolling and succeeding in postsecondary education is essential to reaching the state's goals. The CDHE has several initiatives aimed at supporting high school students as they make the transition to a variety of postsecondary education options; however, Colorado must do more to ensure high school graduates pursue some type of education after they graduate. This report explores both data trends and policy context related to the experience of Colorado's recent high school graduates in postsecondary education through three sections: (1) Postsecondary enrollment trends; (2) Leading indicators of postsecondary success; and (3) Progress toward a credential. Consistent with the commitments outlined in Colorado's goal to erase equity gaps, selected data are provided by gender, race/ethnicity, and income.
