How to calculate the 12-month experience rule for category-based draws
IRCC's category-based Express Entry draws — STEM, healthcare, trades, transport, agriculture, French — all require at least 12 months of continuous full-time work experience in a single NOC code within the past 3 years. The math sounds simple. In practice, part-time hours, gaps, and employer changes trip up most applicants. Here is how to count the months IRCC will actually accept.
The IRCC definition of "full-time" experience
- Full-time: 30 paid hours per week.
- Equivalent part-time: any combination totalling 1,560 paid hours over 12 months (30 × 52). Hours above 30/week in a single job do not count as overtime — they cap at 30.
- Same NOC: all hours must be under the same NOC 2021 code. Two jobs under different NOCs cannot be combined.
- Paid: unpaid internships, volunteer work, and work performed during full-time study are excluded.
Three worked examples
Example 1 — broken weeks, same employer
You worked 40 hrs/week from Jan 2024 to Aug 2024 (8 months = 1,280 hours, capped at 30/wk = 960 countable hours). You took 3 months off, then returned at 35 hrs/wk from Dec 2024 to Apr 2025 (5 months × 4.33 wks × 30 = 650 hours). Total countable: 1,610 hours → qualifies.
Example 2 — two part-time jobs, same NOC
Job A: 18 hrs/week as a registered nurse (NOC 31301) for 12 months = 936 hours.
Job B: 14 hrs/week as a registered nurse (NOC 31301) for 12 months = 728 hours.
Total: 1,664 hours under NOC 31301 → qualifies. Both letters must show the same NOC's main duties.
Example 3 — employer switch under the same NOC
You worked as a software engineer (NOC 21231) at Company A for 8 months at 40 hrs/wk, then moved to Company B in the same role for 5 months at 40 hrs/wk. Total 13 months at 30 countable hours = ~1,690 hours → qualifies. You need a reference letter from both employers, each covering the NOC 21231 main duties.
Documenting the 12 months
- One reference letter per employer, on company letterhead, with start/end dates, hours per week, salary, and detailed duties.
- Pay stubs and T4s (or country equivalents) covering the full window.
- For part-time: explicit weekly hours so the officer can do the math.
- Run every reference letter through a NOC duty-match check before submission — a 12-month claim that fails the duties test is worse than no claim at all.

- What is the 12-month work experience rule for Express Entry?
- To qualify for most Express Entry programs and category-based draws, you must have at least 12 months of full-time (or equivalent part-time) paid work experience in a single NOC code within the past 10 years (or past 3 years for the Canadian Experience Class). The 12 months must be cumulative and continuous in the same NOC.
- Does part-time work count toward the 12 months?
- Yes. IRCC defines full-time as 30 hours per week. Two part-time jobs at 15 hours per week each in the same NOC for 12 months equal one year of full-time experience. You cannot combine hours from different NOC codes.
- Do unpaid internships or self-employment count?
- Unpaid internships, volunteer work, and work done while a full-time student do not count. Self-employment counts for some programs (FSW, PNP) but not for the Canadian Experience Class. You must be able to prove the work with contracts, invoices, tax records, and client letters.
