Are there any skill levels or categories for such occupations as carpenters or electricians in English-speaking countries? If yes, how to say it correctly: a capenter of third skill level or a carpenter, category 3? Maybe there some other variants....

Question

Answer

There are levels, but the terminology may vary by county.  I would google the levels by country. You'll probably find things such as:      apprentice, journeyman, master,   etc.
