What level of skill does a Mistress need to obtain in order to use the term "professional Dominatrix?"

To my knowledge, there is no such thing as a master's degree or doctorate in BDSM. Aside from the the outstanding Glamour Domme Alliance, Dommes do not belong to a professional association and there is no set of criteria for using this term. Anyone can call themselves a ProDomme. To be blunt, a number of retired sex workers have retreated to the BDSM scene without the benefit of any training. This is very unfortunate because untrained Dommes have the potential to injure a sub.

For some submissives simple beating is enough and these women have been able to continue in business. I can also sympathize with subs who have described sessions with unskilled Mistresses as being "lingerie modeling with an attitude or paid punishment."
