Each course of study, except on-demand courses, must be conducted in a classroom or other facility that is adequate to comfortably accommodate the faculty and the number of students enrolled. The education provider may limit the number of students enrolled in a course. Approved courses must not be held on the premises of a company doing business in the regulated area, except for company-sponsored courses allowed by statute or noncompany-sponsored courses offered by a bona fide trade association. A bona fide trade association may offer noncompany-sponsored courses on the premises of an insurance company or agency so long as the course is not restricted to employees or appointed agents of the insurance company or agency.
