Ohio Rev. Code § 3319.18
If an entire school district or that part of a school district which comprises the territory in which a school is situated is transferred to any other district, or if a new school district is created, the teachers in such districts or schools employed on continuing contracts immediately prior to such transfer, or creation shall, subject to section 3311.83, 3319.17, or 3319.171 of the Revised Code, have continuing service status in the newly created district, or in the district to which the territory is transferred.
The limited contracts of the teachers employed in such districts or schools immediately prior to such transfer, or creation, shall become the legal obligations of the board of education in the newly created district, or in the district to which the territory is transferred, subject to section 3311.83, 3319.17, or 3319.171 of the Revised Code. The teaching experience of such teachers in such prior districts or schools shall be included in the three years of service required under section 3319.11 of the Revised Code for a teacher to become eligible for continuing service status.
Teachers employed on limited or continuing contracts in an entire school district or that part of a school district which comprises the territory in which a school is situated which is transferred to any other district or which is merged with other school territory to create a new school district, shall be placed, on the effective date of such transfer or merger, on the salary schedule of the district to which the territory is transferred or the newly created district, according to their training and experience. Such experience shall be the total sum of the years taught in the district whose territory was transferred or merged to create a new district, plus the total number of years of teaching experience recognized by such previous district upon its first employment of such teachers.
The placement of the teachers on the salary schedule, pursuant to this section, shall not result, however, in the salary of any teacher being less than the teacher's current annual salary for regular duties, in existence immediately prior to the merger or transfer.
When suspending contracts in accordance with an administrative personnel suspension policy adopted under section 3319.171 of the Revised Code, a board may consider years of teaching service in the previous district in its decision if it is a part of the suspension policy.
