When the exemption has once been granted, renewal of such exemptions for each succeeding school year may be conditioned by the director, with the approval of the board, upon proof of achievement in the basic skills of arithmetic, the communicative arts of reading, writing, grammar, and spelling, and an understanding of United States history, history of Iowa, and the principles of American government, by persons of compulsory school age exempted in the preceding year, which shall be determined on the basis of tests or other means of evaluation selected by the director with the approval of the state board. The testing or evaluation, if required, shall be accomplished prior to submission of the request for renewal of the exemption. Renewal requests shall be filed with the director on or before April 15 of the school year preceding the school year for which the applicants desire exemption.
