In such countries, nothing can stop individuals who see language as a marketable commodity from opening their own schools, hiring and underpaying unqualified teachers, and using illegally copied materials. I am familiar with one such school that doesn't even pay its teachers. A third defining characteristic of a profession is the existence of a disciplinary base. This theoretical and empirical basis is what distinguishes some professions from trades and crafts. They, too, shift with time, according to dominant meanings and values.
Education is a hybrid, drawing on a range of disciplines such as psychology and sociology.
Partly because of this, we don't have a shared set of rules of the game. In fact, we don't even come close. The fourth and final criterion is that of advocacy. Most professions have professional associations, and a key function of such associations is to act as advocates for the profession. They do this by attempting to influence legislators, either to create legislation that is seen to be advantageous to the profession or to oppose legislation that is seen as inimical to the profession.
