Dual Credit allows students to earn high school and college credit for the same course simultaneously. These courses may be taught on the high school or college campus, or online. Students may be asked to pay a tuition fee in order to enroll (this will vary according to school and district policy).
In Dual Credit, a student is enrolled in a course which allows him/her to earn high school credit and college credit simultaneously. This course may be taught on a college campus or on a high school campus, but it will be in conjunction with a college or university.
Dual Enrollment is very similar to Dual Credit. However, with dual enrollment, the student will actually be enrolled in both high school and college. Therefore, the classes are nearly always taught on the college campus and the student will often be taking multiple college courses.
A Middle College or an Early College is a high school located on a college campus that targets students whose demographics are traditionally underrepresented on college campuses. It will typically have a small enrollment and will focus on advising for college readiness. These schools often provide students the opportunity to take courses for both high school and college credit.
