Ohio Rev. Code § 145.36
A member who has elected disability coverage under this section, has not attained the applicable age, and is determined by the public employees retirement board under section 145.35 of the Revised Code to qualify for a disability benefit shall be retired on disability under this section.
The applicable age is sixty if the member is described in division (A) or (B) of section 145.32 or division (A), (B), or (E)(1), (3), or (4) of section 145.332 of the Revised Code. It is sixty-two if the member is described in division (C) of section 145.32 or division (E)(2) or (5) of section 145.332 of the Revised Code.
Upon disability retirement, a member shall receive an annual amount that shall consist of:
Where the recipient is not receiving a disability benefit under section 145.37 of the Revised Code and is receiving a disability benefit from either the state teachers retirement system or the school employees retirement system, the recipient shall not be eligible for service credit based upon the number of years and fractions thereof between the date of disability and attained age sixty as provided for in this division.
In no case shall disability retirement be less than thirty per cent or more than seventy-five per cent of the member's final average salary, except that it shall not exceed any limit to which the retirement system is subject under section 415 of the "Internal Revenue Code of 1986," 100 Stat. 2085, 26 U.S.C.A. 415, as amended.
A year of service for the purpose of disability retirement is a complete year of full-time employment, or the equivalent thereof. The public employees retirement board is the final authority in determining the eligibility of a member for disability retirement.
