Concurrent enrolment (BE) or concurrent enrollment (AE) is a program through which students earn college credit for courses taken during high school. Students enroll at a university or college to attain high school and/or college credit for these courses. More broadly, it can refer to a student taking multiple courses simultaneously at different educational institutions. Technically, according to  National Alliance of Concurrent Enrollment Partnerships NACEP] which accredits these programs, concurrent enrollment refers to high school-college partnerships that offer high school students the opportunity to take college courses in their high schools during the regular school day and the courses are taught by trained high school teachers.
