The Canadian Language Benchmark (CLB) is Canada's official language assessment framework for immigration purposes. IRCC (Immigration, Refugees and Citizenship Canada) converts your IELTS, TOEFL, or CELPIP scores into CLB levels to determine immigration eligibility and CRS points. This guide explains exactly how the conversion works.
What Is the CLB?
CLB stands for Canadian Language Benchmark — a 12-level scale that describes English language ability, from basic (CLB 1) to advanced professional (CLB 12). IRCC uses CLB levels for:
- Determining eligibility for Express Entry programmes
- Calculating CRS (Comprehensive Ranking System) points
- Assessing eligibility for study permits (SDS pathway)
- Post-Graduation Work Permit (PGWP) language requirement
IELTS to CLB Conversion (Official IRCC Table)
| CLB Level | IELTS Listening | IELTS Reading | IELTS Writing | IELTS Speaking |
|---|---|---|---|---|
| CLB 4 | 4.5 | 3.5 | 4.0 | 4.0 |
| CLB 5 | 5.0 | 4.0 | 5.0 | 5.0 |
| CLB 6 | 5.5 | 5.0 | 5.5 | 5.5 |
| CLB 7 | 6.0 | 6.0 | 6.0 | 6.0 |
| CLB 8 | 7.5 | 6.5 | 6.5 | 6.5 |
| CLB 9 | 8.0 | 7.0 | 7.0 | 7.0 |
| CLB 10 | 8.5 | 8.0 | 7.5 | 7.5 |
| CLB 11 | 9.0 | 8.5 | 8.0 | 8.0 |
| CLB 12 | 9.0 | 9.0 | 9.0 | 9.0 |
How CLB is calculated: Each skill converts to a CLB level individually. Your CLB is the lowest of the four skill conversions — not the average.
Critical Example: CLB Trap
| Your IELTS Score | Individual CLBs | Your CLB |
|---|---|---|
| L:8.0, R:7.0, W:7.0, S:7.0 | L:CLB9, R:CLB9, W:CLB9, S:CLB9 | CLB 9 |
| L:7.5, R:7.0, W:7.0, S:6.0 | L:CLB8, R:CLB9, W:CLB9, S:CLB7 | CLB 7 (limited by Speaking) |
| L:6.0, R:6.0, W:6.0, S:5.5 | L:CLB7, R:CLB7, W:CLB7, S:CLB6 | CLB 6 (limited by Speaking) |
A single skill below your target CLB drops your entire CLB level.
TOEFL to CLB Conversion
| CLB Level | TOEFL Listening | TOEFL Reading | TOEFL Writing | TOEFL Speaking |
|---|---|---|---|---|
| CLB 4 | 4 | 4 | 6 | 14 |
| CLB 5 | 5 | 4 | 10 | 14 |
| CLB 6 | 9 | 4 | 14 | 18 |
| CLB 7 | 18 | 15 | 17 | 20 |
| CLB 8 | 22 | 19 | 20 | 22 |
| CLB 9 | 25 | 23 | 24 | 26 |
| CLB 10 | 27 | 26 | 27 | 28 |
CLB Requirements by Programme
| Immigration Pathway | Minimum CLB |
|---|---|
| Federal Skilled Worker (FSW) | CLB 7 in all four skills |
| Canadian Experience Class (CEC) — TEER 0/1 | CLB 7 in all four skills |
| CEC — TEER 2/3 | CLB 5 in all four skills |
| Study permit SDS (faster processing) | CLB 7 (IELTS 6.0 each skill) — Academic or General |
| PGWP language requirement | CLB 7 (as of November 2024 rule) |
| Provincial Nominee Programs | Varies (CLB 4–7 typically) |
CLB and CRS Points
Higher CLB = more CRS points = better chance of PR invitation:
| CLB Level | CRS Language Points (First Language, Single) |
|---|---|
| CLB 6 | 6 |
| CLB 7 | 6 |
| CLB 8 | 9 |
| CLB 9 | 12 |
| CLB 10 | 12 |
| CLB 11 | 12 |
| CLB 12 | 12 |
Note: These are per-skill points. Total first-language points: sum of all four skills × per-skill points.
The practical impact: Moving from CLB 7 (IELTS 6.0 each) to CLB 9 (IELTS 7.0–8.0 each) earns approximately 24 additional CRS points. In competitive draws, this difference can be decisive.
CELPIP to CLB (For Canada-Only Test)
CELPIP (Canadian English Language Proficiency Index Program) is accepted by IRCC and is taken entirely in Canada:
| CLB 7 | CELPIP 7 in each skill |
|---|---|
| CLB 9 | CELPIP 9 in each skill |
CELPIP is a fully computer-based test taken at Paladin Testing Centres in Canada — a popular option for applicants already in Canada on a study or work permit.
Prepare for IELTS with Gabble — CLB 7 requires IELTS 6.0 in each skill; CLB 9 (for maximum CRS points) requires IELTS 7.0–8.0 each. AI-powered speaking and writing feedback with instant band scores.
