Iowa Code § 290.4
The state board of education in all matters triable before it shall have power to issue subpoenas for witnesses, which may be served by any peace officer, compel the attendance of those thus served, and the giving of evidence by them, in the same manner and to the same extent as the district court may do, and such witnesses and officers may be allowed the same compensation as is paid for like attendance or service in such court, which shall be paid out of the general fund of the proper school corporation, upon the certificate of the state board to and warrant of the secretary upon the treasurer; but if the board is of the opinion that the proceedings were instituted without reasonable cause therefor, or if, in case of an appeal, it shall not be sustained, it shall enter such findings in the record, and tax all costs to the party responsible therefor. A transcript thereof shall be filed in the office of the clerk of the district court and a judgment entered thereon by the clerk, which shall be collected as other judgments.
