Service credit purchased under this section shall be included in the member's total service credit. Credit may be purchased for the following:
The number of years of service purchased under this section shall not exceed the lesser of five years or the member's total accumulated number of years of Ohio service.
For each year of service purchased under this section, a member shall pay to the school employees retirement system for credit to the member's accumulated account an amount equal to the member's retirement contribution for full-time employment for the first year of Ohio service following termination of the service to be purchased. To this amount shall be added an amount equal to compound interest at a rate established by the school employees retirement board from the date of membership in the school employees retirement system to date of payment. A member may choose to purchase only part of such credit in any one payment, subject to board rules.
A member is ineligible to purchase under this section service that is used in the calculation of any retirement benefit currently being paid or payable in the future to the member under any other retirement program, except social security. At the time the credit is purchased, the member shall certify on a form furnished by the retirement board that the member does and will conform to this requirement.
