[1][2] The Occupational Outlook Handbook of the U.S. Department of Labor lists the following as typical tasks for a glazier:[3] The National Occupational Analysis recognized by the Canadian Council of Directors of Apprenticeship separates the trade into 5 blocks of skills, each with a list of skills, and a list of tasks and subtasks a journeyman is expected to be able to accomplish:[4] Tools used by glaziers "include cutting boards, glass-cutting blades, straightedges, glazing knives, saws, drills, grinders, putty,scrapers, sandpaper, sanding blocks, 5 in 1's respirator/dust mask and glazing compounds.

A large portion of glaziers in the United States are members of the IUPAT, the International Union of Painters and Allied Trades which offers its own apprenticeship program which consists of 8000 hours of on the job training and 4 years of classroom education.

[1] In Canada, glaziers usually go through a formal apprenticeship which includes about four years of on-the-job experience combined with classroom study in order to get certified.

[6] In Australia, while you do not need formal qualifications to work as a glazier, it is usual for apprentices to complete a Certificate III in Glass and Glazing as part of their training.

[1][3] The use of heavy equipment may also cause injury: the National Institute for Occupational Safety and Health (NIOSH) reported in 1990 that a journeyman glazier died in an industrial accident in Indiana after attempting to use a manlift to carry a thousand-pound case of glass which the manlift did not have capacity to carry.
