An apprentice, after five years of work, can be a master, just by practcising.
That's why the universities of Oxford and Cambridge give Master's degree to everyone that gets a Bachelor's degree after five years, without further examination or coursework (note that these are MAs only, not MRes, MPhil or MBA degrees, which typically require 1-2 years of studies, exams and theses).
Historically, the academic Master was seen as equivalent to a Master in a craft (e.g. philosophy <=> carpentry).
