(2) The practice of chiropractic, except the administration of a chiropractic adjustment, by a person who is a regular senior student in an accredited school of chiropractic approved by the commission if the practice is part of a regular course of instruction offered by the school and the student is under the direct supervision and control of a chiropractor duly licensed pursuant to this chapter and approved by the commission.
