A statement for tuition is sent from Smart Tuition after completion of enrollment contract. One half of the tuition, plus the charges for the TRP and SAI, and the Parent Association dues must be paid no later than June 15. The second half of the tuition is due no later than November 15. Parents who find it more convenient to pay monthly may want to consider the Thayer 10-Month Payment Plan. Details for this plan are available from the Business Office (781.380.0503). It should be noted that a student will not be admitted to class if the tuition and fees have not been paid.
