New Jersey Statutes Title 18A. Education 18A § 66-15.1

a. A member who is a member of another State-administered retirement system or pension fund at the time of enrollment in the Teachers' Pension and Annuity Fund and who does not contribute to the other system or fund after that time may transfer the service credit in the other system or fund to the Teachers' Pension and Annuity Fund upon application and transfer of the member's contributions from the other system or fund to the fund. If the member has withdrawn the contributions to the other retirement system or pension fund, the member may purchase credit for the service in the other system or fund. The purchase shall be made in the same manner and be subject to the same terms and conditions provided for the purchase of previous membership service by N.J.S.18A:66-9.

b. A member of the retirement system who had established service credit in a municipal or county retirement system or pension fund, and who was ineligible to transfer the service credit to the retirement system and withdrew contributions from the municipal or county retirement system or pension fund, may purchase credit for all of the member's service in that retirement system or pension fund by paying into the annuity savings fund the amount required by applying the factor, supplied by the actuary, as being applicable to the member's age at the time of the purchase, to the member's salary at that time, or to the highest annual compensation for service in this State for which contributions were made during any prior fiscal year of membership, whichever is greater. The terms of the purchase and the credit granted shall be identical, except as otherwise herein provided, to those stipulated for the purchase of previous membership service by members of the retirement system as provided by N.J.S.18A:66-9.

c. A member who is a member of the Public Employees' Retirement System, established pursuant to P.L.1954, c. 84 (C.43:15A-1 et seq.), at the time of enrollment in the Teachers' Pension and Annuity Fund and who within three years of the date of that enrollment ceases to be an active contributing member of the Public Employees' Retirement System may transfer all service credit in the Public Employees' Retirement System to the Teachers' Pension and Annuity Fund upon application and transfer of the member's contributions from the Public Employees' Retirement System to the Teachers' Pension and Annuity Fund. If the member has withdrawn the contributions to the Public Employees' Retirement System, the member may purchase credit for the service. The purchase shall be made in the same manner and be subject to the same terms and conditions provided for the purchase of previous membership service by N.J.S.18A:66-9.
