A teacher who desires to purchase service credit under subdivision 1 must apply with the executive director to make the purchase. The application must include:
The Teachers Retirement Association must grant allowable service credit to the teacher making the purchase for the period being purchased upon receipt of the purchase payment amount. Payment must be made by the earlier of the teacher's termination of teaching service or one year after the executive director's approval of the teacher's application to purchase service credit. Purchasing allowable service credit under this section does not change the date the teacher first became a member of the association for the purpose of computing an annuity under section 354.44, subdivision 6.
The purchase payment amount is the amount determined under section 356.551 for the period or periods of service requested, except that, for purposes of calculating the purchase payment amount to purchase allowable service credit for service as a teacher in another state that occurred before becoming a member of the association or between periods of teaching service as a member of the association, section 356.551, subdivision 2, paragraph (c), shall not apply.
