It would probably be quite difficult to hammer together some "agreed upon standard" for "levels" of proficiency in X_language. That said, it's been done before...with spoken languages for the Military. Taking the DLPT will give you a rating on your proficiency, and then you get both the credentialing and then additional pay (Once upon a time I took it for Arabic and scored some 0+s). It'd be hard, but I don't think it would be impossible to do it for some kind of development credential. http://www.dliflc.edu/wp-content/uploads/2015/03/Generic-Fam-Guide-MC-CBu-updated.pdf http://www.dliflc.edu/wp-content/uploads/2015/03/Generic-Fam... https://en.wikipedia.org/wiki/Defense_Language_Proficiency_Tests https://en.wikipedia.org/wiki/Defense_Language_Proficiency_T...
