Language Score Mapping: CLB, IELTS, CELPIP, PTE, and TOEFL Conversion Table (2025)
Language score equivalency is confusing — a CLB 9 is not the same as an overall IELTS 9.0. This guide provides the official IRCC conversion tables for IELTS, CELPIP, and PTE, explains component-by-component scoring, and shows how score mapping affects your CRS points.
Why Score Mapping Matters for Immigration
A common mistake among Express Entry applicants is treating language test scores as a single overall number. Immigration systems — especially Canada's — evaluate each of the four language skills (reading, writing, listening, speaking) independently. Your overall score is irrelevant; what matters is the CLB level achieved in each individual skill component.
A candidate who achieves IELTS 8.0 overall but has a 6.5 in writing does not have CLB 9 writing — they have CLB 7 writing. This distinction can cost 16–28 CRS points.
What Is the CLB Scale?
The Canadian Language Benchmarks (CLB) is a standardized scale from CLB 1 (beginner) to CLB 12 (near-native proficiency) used by IRCC to assess English ability. Each accepted test maps to CLB levels per skill component.
For immigration purposes:
- Express Entry minimum: CLB 7 in all four skills (FSWP, CEC, FSTP)
- Maximum CRS language points: CLB 9+ in all four skills of the first official language
- CLB 10, 11, 12 all receive the same maximum points as CLB 9
Official IRCC Conversion Tables
IELTS General Training to CLB
| CLB Level | Listening | Reading | Writing | Speaking |
|---|---|---|---|---|
| CLB 10 | 8.5 | 8.0 | 7.5 | 7.5 |
| CLB 9 | 8.0 | 7.0 | 7.0 | 7.0 |
| CLB 8 | 7.5 | 6.5 | 6.5 | 6.5 |
| CLB 7 | 6.0 | 6.0 | 6.0 | 6.0 |
| CLB 6 | 5.5 | 5.0 | 5.5 | 5.5 |
| CLB 5 | 5.0 | 4.0 | 5.0 | 5.0 |
| CLB 4 | 4.5 | 3.5 | 4.0 | 4.0 |
Important: IELTS Academic and IELTS General Training use the same CLB conversion table. Either version is accepted for Canadian immigration.
CELPIP-General to CLB
CELPIP uses a direct 1-to-1 CLB mapping:
| CLB Level | Listening | Reading | Writing | Speaking |
|---|---|---|---|---|
| CLB 10 | 10 | 10 | 10 | 10 |
| CLB 9 | 9 | 9 | 9 | 9 |
| CLB 8 | 8 | 8 | 8 | 8 |
| CLB 7 | 7 | 7 | 7 | 7 |
| CLB 6 | 6 | 6 | 6 | 6 |
| CLB 5 | 5 | 5 | 5 | 5 |
| CLB 4 | 4 | 4 | 4 | 4 |
CELPIP scores directly equal the CLB level — no conversion needed. A CELPIP 9 in all four skills = CLB 9 in all four skills.
PTE Academic to CLB
| CLB Level | Listening | Reading | Writing | Speaking |
|---|---|---|---|---|
| CLB 10 | 88–90 | 88–90 | 90 | 89–90 |
| CLB 9 | 82–87 | 78–87 | 79–89 | 79–88 |
| CLB 8 | 71–81 | 60–77 | 69–78 | 65–78 |
| CLB 7 | 60–70 | 51–59 | 60–68 | 59–64 |
| CLB 6 | 47–59 | 40–50 | 51–59 | 46–58 |
| CLB 5 | 39–46 | 33–39 | 42–50 | 35–45 |
| CLB 4 | 28–38 | 24–32 | 32–41 | 24–34 |

French Language Benchmarks (NCLC)
French language ability is measured in the Niveaux de compétence linguistique canadiens (NCLC), which mirrors the CLB 1–12 scale.
Accepted French tests for IRCC:
| Test | Provider | NCLC Mapping |
|---|---|---|
| TEF Canada | Chambre de commerce et d'industrie de Paris | Direct NCLC equivalency table |
| TCF Canada | France Éducation International | Direct NCLC equivalency table |
CRS points for French (second language) — single applicant:
| NCLC Level (all 4 skills) | CRS Points |
|---|---|
| NCLC 9+ in all four | 24 |
| NCLC 7–8 in all four | 16 |
| NCLC 7+ in all four (first language French, English CLB 5+) | +25 bilingual bonus |
How CLB Level Maps to CRS Points
First Language (English or French) — Single Applicant
| CLB Level | Reading | Writing | Listening | Speaking |
|---|---|---|---|---|
| CLB 10+ | 32 | 32 | 32 | 32 (total: 128) |
| CLB 9 | 32 | 32 | 32 | 32 — wait, same as 10? Let me clarify |
Actually the maximum for first language (single applicant) is 136 total across all four skills combined at CLB 9+. Per skill:
| CLB Level (per skill) | Points per Skill Component |
|---|---|
| CLB 10+ | 34 |
| CLB 9 | 34 |
| CLB 8 | 22 |
| CLB 7 | 16 |
| CLB 6 | 8 |
| CLB 5 or below | 6 |
| CLB 4 | 6 |
Total first language maximum: 34 × 4 = 136 CRS points (CLB 9+)
Critical calculation: An applicant who achieves CLB 9 in listening, reading, and speaking but CLB 8 in writing does NOT receive 136 first-language points. They receive:
- 34 (listening) + 34 (reading) + 34 (speaking) + 22 (writing) = 124 points — losing 12 points from maximum due to one CLB 8.
This is why retaking the test to improve a single CLB 8 component to CLB 9 is worth serious consideration: 12 CRS points can mean the difference between receiving an ITA in a draw and missing it.
Strategic Implications
IELTS 7.0 in writing = CLB 9: The CLB 9 threshold for IELTS writing is 7.0 — not 7.5. Many candidates over-prepare for 7.5 in writing when 7.0 already delivers CLB 9.
IELTS vs. CELPIP — where to retake: If you scored IELTS 6.5 in speaking (CLB 8), switching to CELPIP and achieving CELPIP 9 in speaking gives you CLB 9. Different test formats suit different candidates.
PTE listening 82+ = CLB 9: PTE's highest-impact area for most candidates is listening — the range is wide (60–90). Focused PTE listening preparation (summarize spoken text, fill in blanks) can lift CLB from 8 to 9 in one component.
