What is the proper term to describe the levels of experience for a trade?

For the life of me I can't recall or even Google the proper term to describe the levels of experience for a given trade.

For example let's say there are 5 levels of experience to trade x:

  • Rookie
  • Journeyman
  • Veteran
  • Craftsman
  • Luminary

What hypernym would describe these levels of experience?


I doubt there's any generally-accepted terminology, but in context, grade, level, or (more formally) competence would all be understood and accepted.


This article on medieval guilds calls them stages.


I have heard them called ranks when talking about guilds (medieval and modern).
