What is National Occupation Classification (NOC)?
The National Occupational Classification (NOC) is a system used in Canada to classify and categorize differe occupations in the coury’s labor market. It is a standardized reference tool that provides a consiste framework for understanding and organizing occupational information.
The main purpose of the NOC is to facilitate the collection, analysis, and dissemination of occupational data for various purposes, including labor market research, workforce planning, career information, and immigration programs. It helps to provide a common language for describing job duties, skills, and qualifications across differe industries and sectors.
