Ohio Rev. Code § 124.25
The director of administrative services shall require persons applying for an examination for original appointment in the service of the state to file with the director or the director's designee, within reasonable time prior to the examination, a formal application, in which the applicant shall state the applicant's name, address, and such other information as may reasonably be required concerning the applicant's education and experience. No inquiry shall be made as to religious or political affiliations or as to racial or ethnic origin of the applicant, except as necessary to gather equal employment opportunity or other statistics that, when compiled, will not identify any specific individual.
Blank forms for applications shall be furnished by the director or the director's designee without charge to any person requesting the same. The director or the director's designee may require in connection with such application such certificate of persons having knowledge of the applicant as the good of the service demands. The director or the director's designee may refuse to appoint or examine an applicant, or, after an examination, refuse to certify the applicant as eligible, who is found to lack any of the established preliminary requirements for the examination, who is addicted to the habitual use of intoxicating liquors or drugs to excess, who has a pattern of poor work habits and performance with previous employers, who has been convicted of a felony, who has been guilty of infamous or notoriously disgraceful conduct, who has been dismissed from either branch of the civil service for delinquency or misconduct, or who has made false statements of any material fact, or practiced, or attempted to practice, any deception or fraud in the application or examination, in establishing eligibility, or securing an appointment.
