An Atelier (or botegga in Italian) is the private working studio of a professional painter or sculptor -- one who dedicates time to training a limited number of select students who seek to pursue careers as professional artists.

The instruction offered in the atelier tradition evolved from the apprentice system which, in the case of craftsmen and artisans, dates far back into ancient history.  Apprenticeship training of fine artists dates back to the Renaissance.  A master painter or sculptor trained a group of assistants and apprentices until they were ready to work independently. - Adrian Gottlieb
