To apply for Dual Enrollment at DIU, students must be at the sophomore, junior, or senior level of high school. Students must either attend a private high school with whom DIU has a Dual Enrollment partnership, or be homeschooled. If a student attends a private high school that does not have a Dual Enrollment partnership with DIU, e-mail dual-enrollment@diu.edu to request that we consider a partnership with their school.
