A current junior or senior-level student in a U.S. high school may enroll as a student at Jacksonville College and receive college credit for courses taken and completed successfully (“concurrent enrollment”). Both college credit and high school credit for certain courses taken and completed successfully may be awarded by specific approval of the high school (“dual credit enrollment”). The high school must give permission for students to enroll and should indicate whether the course will be accepted for dual credit. Some courses may be offered on the high school campus. Both concurrent enrollment and dual credit enrollment students, whether on the college campus or on the high school campus, are subject to the published Jacksonville College admission procedures and requirements and other applicable policies.

A course offered on the high school campus is administered by the same policies as those taught on campus, including instructor qualifications, course syllabus, student placement in English or mathematics classes, student grades, and evaluation of course instruction. The student may not enroll in college-level English or math if placement scores indicate that developmental education is needed in those areas. Developmental education cannot be provided while still in high school.

Courses taken by current high school students are placed on an official Jacksonville College transcript that can be presented to another college/university for evaluation of transfer credit. The student should contact the transfer school to determine what courses are required and which Jacksonville College courses satisfy those requirements. An official Jacksonville College transcript cannot be released to anyone other than the high school until an official high school transcript showing graduation is presented to the College. The College will provide library and other student services to students upon request. Each current high school student is assigned to a full-time College faculty member as academic advisor.

Home-schooled students are also eligible to participate in the dual credit concurrent enrollment program. A home-schooled student may enroll in a maximum of two college classes per semester. The student must provide a high school transcript, verifying completion of the sophomore year and a letter of permission from the home school instructor in addition to the application credentials of all high school students.
