If you do not have the structure of a dedicated classroom environment, in which theory, rules, safety and sanitation are taught and valued, how can you ensure that the public's health and safety isn't jeopardized? In a theory classroom and in the practical classroom, safety and sanitation are taught without regard to commerce. How can you ensure that the apprecenticeship program will not be exploited as a low cost method in which to service clients? The public trusts their government to protect their safety.
