Differential tuition is tuition charged to students according to the specific courses they take after they have reached 60 credit hours. Those 60 credits include any AP or IB credits the student transferred from high school coursework. The exception is courses in the College of Business, for which differential tuition is assessed after 30 credit hours.
Differential tuition is not assessed for any student who is classified as a freshman.
Many universities assess differential tuition beginning the freshman year. At CSU, we believe that every student needs the flexibility and time to explore possible majors. Again, for most students except those taking College of Business courses, students have two full years before differential tuition is assessed.
