Each year you receive a TEACH Grant, you must sign a TEACH Grant Agreement to Serve and Promise to Pay (service agreement or ATS).
The TEACH Grant service agreement specifies the conditions under which the grant will be awarded, the teaching service requirements, and includes an acknowledgment by you that you understand that, if you do not meet the teaching service requirements, you must repay the grant as a Federal Direct Unsubsidized Loan with interest accrued from the date the grant funds were first disbursed.
