Learn About Job Classification

I think the best way to learn about the job classification is to go through the official web site of NOC or National Occupational Classification.

The National Occupational Classification is a systematic classification of all the jobs in Canadian Market. Even though it was intended for Canadian, it can be a resource of learning about jobs, its main duties, and employment requirements.

I had included a video of the NOC below.

The site is accessible at:
