May an eighteen to twenty year-old student who takes and passes a class 12 training course upgrade to a class 12 permit upon turning twenty-one without retaking the training course?
Yes.
(1) An eighteen, nineteen or twenty year-old person may take a class 12 training course and pass the corresponding exam; however, he or she may be issued only a class 13 permit. Upon turning twenty-one years of age, such a person who obtains a class 13 permit after taking and passing a class 12 training course and exam may request that a provider or trainer upgrade his or her class 13 permit to a class 12 permit.
(2) The expiration date of an upgraded class 12 permit shall be the same expiration date as the original class 13 permit.
