Ohio Rev. Code § 5119.184
The department of mental health and addiction services may provide educational grants or tuition reimbursements to upgrade the education, training, and professional achievement of its employees, whenever it determines that provision of such grants or reimbursements is essential to the achievement of its goals. The department may enter into agreements with its employees for the purposes of this section. The agreements may require, as a condition of each grant or reimbursement, that the employee continue employment with the department or with another federal, state, or local public agency designated by the department for a period of time stated in the agreement. If an employee does not fulfill the employment requirement stated in the agreement, the department may take action to recover the amount of all educational grants or tuition reimbursements paid to the employee under this section, plus interest at the rate of ten per cent per year calculated from the date of payment of each grant or reimbursement.
