That depends on you! Like all master's programs, our M.S. is 30 units. Any prerequisite courses you need to take are above and beyond the program's 30 units (this also is standard). If you take one course (3 units) per semester, it will take you about ten semesters to complete the program. However, classes will always be available during summer semesters.
500- and 800-Level Courses (500 to 599; 800 to 899) Graduate courses are offered at Penn State Erie, Harrisburg, and University Park. These courses are numbered 500 to 599 and 800 to 899 and are described in the Graduate Degree Programs Bulletin. They are not available to undergraduates unless the student is enrolled in an integrated undergraduate/graduate program.
