15-39.1-15. Withdrawal from fund - Return to teaching
A teacher who has withdrawn from the fund as set forth in this chapter, by returning to teach
in a public school or state institution of this state, may regain service credit for prior teaching by
making the required payment. The required payment is the purchase cost on an actuarial
equivalent basis. If the teacher returns to teach in covered employment after June 30, 2008, the
teacher becomes a tier two member regardless of whether the teacher repurchases service
credit earned while the teacher was a tier one member.
