NOC: Structure

The National Occupational Classification program is in effect a list of job descriptions that have been standardized by the government.

Standardization does a number of things that help in many aspects of government and industry:

  • Immigration officials are better equipped to determine whether or not an immigrant is best for an employment visa to Canada.
  • Corporations have rubrics and standards on which to base promotions and raises.
  • By developing expectations, workers can feel more confident in doing their jobs because they will know in advance of what is expected of them.

NOC Structure

The job descriptions listed in the National Occupational Classification are categorized by similarity. Each job is given a number. Each digit within that number has a meaning to itself.

The first digit is the Skill Type Classification. The next number indicates the Major Group Classification. The third number indicates the Minor group and the fourth number indicates the actual job description.

Below are the 10 Skill Types and their subordinate major categories according to the official National Occupation Classification of Canada website:
