Canada CLB Calculator

What This CLB Calculator Does

The Canadian Language Benchmarks (CLB) is a 12-point scale that Immigration, Refugees and Citizenship Canada (IRCC) uses to measure English ability for immigration programs. The French equivalent is NCLC (Niveaux de compétence linguistique canadiens). Your IELTS, CELPIP, TEF, or TCF test scores convert to CLB or NCLC levels using IRCC’s official equivalency tables. This Canada CLB calculatorperforms the conversion for all four abilities (listening, reading, writing, speaking) and identifies the lowest score — the one IRCC uses for most eligibility checks.

Pick your test, enter your scores per ability, and the calculator shows you each ability’s CLB (or NCLC) level plus the lowest. The lowest is what determines whether you meet the minimum for the Federal Skilled Worker Program (CLB 7) or Canadian Experience Class (CLB 5 or 7 depending on NOC TEER). To see how your CLB scores translate into CRS points, use our Canada CRS score calculator.

IELTS to CLB Conversion (General Training)

IRCC’s official IELTS General Training to CLB equivalencies. IELTS Academic is not accepted for most immigration purposes — you need IELTS General Training:

• CLB 10+: Listening 8.5, Reading 8.0, Writing 7.5, Speaking 7.5
• CLB 9: Listening 8.0, Reading 7.0, Writing 7.0, Speaking 7.0
• CLB 8: Listening 7.5, Reading 6.5, Writing 6.5, Speaking 6.5
• CLB 7: Listening 6.0, Reading 6.0, Writing 6.0, Speaking 6.0
• CLB 6: Listening 5.5, Reading 5.0, Writing 5.5, Speaking 5.5
• CLB 5: Listening 5.0, Reading 4.0, Writing 5.0, Speaking 5.0
• CLB 4: Listening 4.5, Reading 3.5, Writing 4.0, Speaking 4.0

CELPIP to CLB Conversion

CELPIP General converts one-to-one: your CELPIP level IS your CLB level. CELPIP 7 = CLB 7, CELPIP 9 = CLB 9, CELPIP 12 = CLB 12. This is the simplest test-to-CLB mapping. CELPIP is fully computer-based, takes about 3 hours, and results are typically released within 8 calendar days — faster than IELTS. CELPIP is only offered in Canada, the U.S., the UAE, India, the Philippines, and a few other countries.

TEF and TCF to NCLC (French)

French language ability is measured in NCLC levels, parallel to CLB. The two French tests accepted by IRCC are TEF Canada and TCF Canada. Both have different scoring scales:

• TEF Canada — scored out of 360 (listening), 300 (reading), 450 (writing), 450 (speaking). NCLC 7: Listening 249, Reading 207, Writing 310, Speaking 310.
• TCF Canada — scored out of 699 (listening), 699 (reading), 20 (writing), 20 (speaking). NCLC 7: Listening 458, Reading 453, Writing 10, Speaking 10.

French candidates often have a CRS advantage in 2025: French-language category-based draws have had the lowest cutoffs of any draws (sometimes below CRS 400). NCLC 7 or higher across all four French abilities unlocks +25 to +50 additional CRS points, on top of language-ability points in the core score.

What CLB Levels Mean in Practice

• CLB 4–5: Basic functional English — can handle routine conversations and simple texts. Minimum for some CEC NOC TEER 4/5 streams and citizenship test.
• CLB 6: Adequate intermediate English — can manage most everyday situations and follow general workplace communication.
• CLB 7: Strong intermediate English. The benchmark for Federal Skilled Worker eligibility and many CEC TEER 0/1 streams. Most successful Express Entry candidates have CLB 7+.
• CLB 8–9: Upper-intermediate to advanced. CLB 9 across all four abilities is the threshold for the more generous skill-transferability bonuses in CRS (50 vs 25 points).
• CLB 10–12: Near-native to native fluency. Caps out the language portion of the CRS core score.

How CLB Scores Affect Your CRS

Language points are one of the largest components of the CRS score. Going from CLB 7 to CLB 9+ on all four abilities can add 50–70 points to the core score plus more through skill-transferability bonuses — often the single highest-leverage move available to a candidate who isn’t pursuing a Provincial Nomination. Pair this calculator with our Canada CRS calculator to model how a higher CLB level would change your overall score before you book a re-test.

For citizenship applicants, the language bar is lower — CLB 4 is the threshold for naturalization, much easier than the Express Entry minimums. If you’re tracking days toward citizenship, our Canada citizenship calculator handles the 1,095-day physical presence math.
