The Commissioner of Education shall at least once each year inspect each accredited school to ascertain whether its standards of efficiency are maintained. If upon examination the Commissioner finds that any school is not maintaining required standards of efficiency, he shall by written notice to the head of the school state clearly in what manner such school is deficient, and shall direct that the required standards of efficiency be adhered to within a reasonable time stated in the notice. If at the expiration of such time the Commissioner finds that the school so notified has not complied satisfactorily with his directions he shall report the facts fully in writing to the Virgin Islands Board of Education. The Board shall thereupon examine the conditions reported by the Commissioner of Education, and if deemed advisable may by resolution adopted at a regular meeting revoke the certificate of accreditation.
