Applicants for a license to practice osteopathic medicine and surgery must successfully complete an examination prepared or approved by the board. The examination shall be conducted in the English language, shall determine the applicant's fitness to practice osteopathic medicine and surgery, and may be in whole or in part in writing or by practical application on those general subjects and topics of which knowledge is commonly and generally required of applicants who have obtained the doctor of osteopathic medicine and surgery conferred by accredited schools of osteopathic medicine and surgery approved by the board.
