The following is a list of trades in construction.
Among the construction trades, in most industrialized countries, each has a distinct 2-5 year craft apprenticeship education and usually once started a worker remains in a single craft and progresses through ranks of skill for the duration of their career (pre-apprentice, apprentice, and journeyman; some countries include a post-journeyman 'master' level, which in other countries is a company title like leadman, foreman, and superintendent).
While not as formalized in laws as in industrialized countries, the same situation is true through craft traditions in non-industrialized countries.
