Ohio Revised Code Title XXXIII. Education Libraries § 3307.77

(A) As used in this section, “employer” means the employer employing a member of the state teachers retirement system at the time the member commences an absence, or is granted a leave described in this section.

(B) Any member of the state teachers retirement system participating in the STRS defined benefit plan or the STRS combined plan who is, or has been, prevented from making contributions under section 3307.26 of the Revised Code because of an absence due to the member's own illness or injury, or who is, or has been, granted a leave for educational, professional, or other purposes pursuant to section 3319.13, 3319.131, or 3345.28 of the Revised Code or for any other reason approved by the state teachers retirement board, may purchase service credit, not to exceed two years for each such period of absence or leave, either by having deductions made in accordance with division (C) of this section or by making the payment required by division (D) of this section.

(C) If the absence or leave begins and ends in the same year, the member may purchase credit for the absence or leave by having the employer deduct and transmit to the system from payrolls in that year employee contributions on the amount certified by the employer as the compensation the member would have received had the member remained employed in the position held when the absence or leave commenced. The deductions may be made even though the minimum compensation provided by law for the member is reduced thereby, unless the amount to be deducted exceeds the compensation to be paid the member from the time deductions begin until the end of the year, in which case credit may not be purchased under this division. The employer shall pay the system the employer contributions on the compensation amount certified under this division. Employee and employer contributions shall be made at the rates in effect at the time the absence or leave occurred. If the employee or employer rates in effect change during the absence or leave, the contributions for each month of the absence or leave shall be made at the rate in effect for that month.

(D) If the absence or leave does not begin and end in the same year or the member does not purchase the credit under division (C) of this section, a member may purchase credit for the absence or leave by paying to the system the sum of the following for each year of credit purchased:

(E) A member who chooses to purchase service credit under division (D) of this section may choose to purchase only part of the credit for which the member is eligible in any one payment.

(F) The state teachers retirement board may adopt rules to implement this section.
