If we looked at this from a broad point of view, we might realize that some professions use the term “Master”, and some don’t. They use other designations.
I don’t recall ever hearing of a Master Doctor, Master Physician, Master Surgeon, Master Lawyer, Master Attorney, Master Accountant, Master Actuary, Master Professor, Master Realtor, Master Scientist, Master Journalist, Master Engineer, Master Architect, Master Surveyor, or for that matter, Master Pastor. And, though I have heard of educators referred to as “Master Teacher”, I think the term was used informally, or as a special, honorific title. For some but not all of these, a Doctorate is required, and “Master” might seem to be a step down. And for some, not even a master’s degree is required. All of these professions, except perhaps journalism (which may be exempt due to freedom of the press), have some threshhold licensing or other qualification requirement.
The term “Master Builder,” while sometimes used, particularly in a historical context, as, for example, describing those who built cathedrals or pyramids, has, as far as I know, no official status as an earned or recognized title, even though in the construction industry more than perhaps any other, “Master” IS officially used as an ultimate designation, signifying one who through experience and testing has demonstrated superior ability to those of lower “apprentice” and “journeyman” status. So we DO have Master Plumbers, Master Electricians, etc. I assume there are Master Painters as well, since there’s a Master Painters Institute. In many if not most jurisdictions, one cannot obtain a plumbing or electrical permit without the requisite master’s license. Auto service departments are right proud of their Master Mechanics. Orchestra conductors are often called “Maestro”. And one needs a master’s license to captain a ship.
So, do we really need “Master Specifiers?” Do we then need “Apprentice” and “Journeyman” specifiers as well?
And, if you put “M.S.” after your name, would it really mean “Master Specifier” to anyone? Or just make them wonder if you were perhaps a little too proud of your master of science degree?
