A person attending a licensed school of barbering, hairdressing, manicuring, or esthetics and a person apprenticed to a licensed instructor in a shop approved by the board or receiving training from a practitioner of tattooing, permanent cosmetic coloring, or body piercing shall obtain a student permit. A student permit to practice barbering or hairdressing is valid for two years. A student permit to practice esthetics, tattooing, permanent cosmetic coloring, or body piercing is valid for one year. A student permit may not be renewed, but, upon application, the board may issue a new permit to the same person or extend an expired permit to the date of the next scheduled examination. Credit earned under an expired student permit may be transferred to a new permit as determined by the board.
