Using NOC 94204 duties on your resume

Canadian resumes do not list NOC codes. Employers read your job titles, what you did and what came of it. The NOC duties are still a useful checklist: if you did these tasks, say so in your own words and add the numbers that prove it.

For Express Entry, the reference letter from your employer should describe the duties you really performed, in line with this lead statement and most of the main duties, without copying the NOC text word for word. The free reference letter generator checks your duties against NOC 94204 as you write.

• Start each bullet with a strong verb and end it with a result: how many, how often, how fast.
• Use the job title your employer used, even if the NOC title is different.
• Keep immigration details such as your NOC code and permit type off the resume.
