The tuition charge covers costs for instruction and supervised laboratory periods; however, it does not cover the costs of books and supplies. Any future change in tuition or fee rates will be posted in various locations within the school at least one month prior to implementation and will apply to future terms. Quarterly payments in all courses are due on or before the start of each quarter, unless other financing arrangements have been made. Students are charged tuition only for the full and partial quarters that they attend. Prepaid tuition for a quarter beyond that in which a student withdraws is fully refundable.
