All licensed instructors who have not taught in a school, college, or provided on the job training within a period of five years, or who have not attended the annual Board-approved barber examination overview for instructors for two of the years within a five-year period will be required to apply for and take the instructor examinations required by the Board, to insure continued competency as an instructor. Licensed instructors attending the overview during the five year period who are not actively teaching during that time must provide to the Board, at the time of attendance, an affidavit or other proof acceptable to the Board certifying their attendance at the required overview.
