Ohio Rev. Code Ann. § 2151.16

The juvenile judge may appoint and fix the compensation of referees who shall have the usual power of masters in chancery cases, provided, in all such cases submitted to them by the juvenile court, they shall hear the testimony of witnesses and certify to the judge their findings upon the case submitted to them, together with their recommendation as to the judgment or order to be made in the case in question. The court, after notice to the parties in the case of the presentation of such findings and recommendation, may make the order recommended by the referee, or any other order in the judgment of the court required by the findings of the referee, or may hear additional testimony, or may set aside said findings and hear the case anew. In appointing a referee for the trial of females, a female referee shall be appointed where possible.
