This traditional program allows students to earn credits toward a high school diploma in a classroom setting.  Instruction is individualized so each student works on the specific courses he or she needs.  Students are required to attend class regularly. Classes are scheduled for two-hours and meet Monday through Friday and are available mornings, afternoons, and evenings.  Courses are textbook and computer-based.  The coursework is self-paced so completion and an earned diploma are achieved by the determination of each student.
