No apprentice may practice independently. An apprentice may perform any and all acts necessary for professional training within the scope of this chapter when such acts are performed in compliance with board rule, including immediate personal supervision of the apprentice by a licensed instructor. Establishments employing apprentices shall keep a daily work record of the attendance of such apprentices and shall, upon the termination of such apprenticeship, certify to the board the total number of hours worked and the types of instruction given to the apprentice. All apprenticeships must be completed within three (3) years from the time of commencement, unless an extension is approved by the board for good cause. The specific time allowed for each apprenticeship shall be set by board rule.
