645—221.6 (136C,147,149) Examination and proficiency evaluation. Except as otherwise provided in this chapter, no person shall operate radiation emitting equipment in any podiatry office without first having also successfully passed a written examination with a score of 70 percent or greater given under standard, controlled conditions by the board of podiatry examiners and proctored by appropriate personnel. The examination will be given in June and December and at other times at the discretion of the board.
	 221.6(1) In the event a podiatry assistant under student status pursuant to subrule 221.5(2) fails twice to successfully complete the examination, a third examination may be taken so long as the third examination is taken within 60 days after expiration of the 12-month period of student status. In the event the podiatry assistant fails the third examination, student status shall be revoked and the podiatry assistant shall be deemed ineligible to participate in podiatric radiography under student status unless the student status is obtained pursuant to subrule 221.5(2).
	 221.6(2) A podiatry assistant who takes the examination for issuance of a renewal as defined in subrule 221.9(6) of a certificate is allowed to take the examination not more than two times. The board may require the podiatry assistant to take remedial training prior to being allowed to retake the examination. Podiatry assistants in this category may not participate in podiatric radiography before successful completion of the examination and issuance of a certificate or issuance of a renewal of an existing certificate.
	 221.6(3) A podiatry assistant who holds a permit to practice limited diagnostic radiography in extremities or foot by the bureau of environmental health may apply for and be granted a certificate in podiatric radiography without meeting the training requirements in rule 221.3(136C,147,149) or the exam requirements in rule 221.6(136C,147,149). A temporary permit issued by the bureau of environmental health does not qualify under this subrule.
	 221.6(4) Certification by endorsement of equivalency training. Any person who is the holder of a current certificate in podiatric radiography issued by another state, jurisdiction, agency or recognized professional registry may, upon presentation of the certificate to the board, be considered to meet the requirements of subrules 221.3(1) to 221.3(3) provided that the board finds that the standards and procedures for certification in the state, jurisdiction, agency or recognized professional registry which issued the certificate afford protection to the public equivalent to that afforded by this chapter.
