How do I know if my job's NOC/TEER code and experience qualify for a stream?

Start with the official NOC tool on canada.ca and match your actual day-to-day duties, not just your job title, to the code's main duties. Then check the stream's rules: many require a specific TEER level, a set amount of full-time (or equivalent) experience, and sometimes an in-demand occupation list. If your duties only partly match, or your title sounds different from your work, it is worth documenting your duties carefully with reference letters before you apply.
