National Occupational Classification

The National Occupational Classification, or NOC, is a systematic taxonomy in English of all occupations in the Canadian labour market. As a Canadian government publication it is concurrently published in French as Classification nationale des professions. Organized into two volumes, it describes 923 distinct occupations in terms of aptitudes, interests, education, physical activities, and other qualifiers. A separate index further classifies over 25,000 job titles from the listed occupations.
