Dual enrollment is a program that allows high school students to take college-level courses and earn credits toward both their high school diploma and a postsecondary degree at the same time. It doesn’t matter if you go to private school or public school – dual enrollment is available to almost all U.S. high school students. If you want to graduate college as soon as possible, save money on tuition, and better prepare yourself for university curriculum, dual enrollment could be for you.
