Ohio Rev. Code § 3301.50
Except as otherwise provided under division (B) of section 3301.54 of the Revised Code, the issuing of any educator license designated for teaching in a preschool setting pursuant to section 3319.22 of the Revised Code shall not be construed as requiring any person who does not hold such a license to obtain one in order to be employed as a teacher in a pre-kindergarten program. However, a person hired after July 1, 1988, to direct a preschool program regulated by the department of children and youth under sections 3301.52 to 3301.57 of the Revised Code, other than a program operated by a nontax-supported eligible nonpublic school, shall hold a valid educator license designated as appropriate for teaching or being an administrator in a preschool setting issued pursuant to section 3319.22 of the Revised Code plus the four courses required by division (A)(1) of section 3301.54 of the Revised Code, unless division (A)(4) of that section applies to the person.
