CLB Score Explained: How IELTS, CELPIP, and PTE Convert

Updated July 2026 · 5 min read

Whichever English test you take, your raw result isn't actually what IRCC uses to assess your application — it gets converted into a Canadian Language Benchmark (CLB) score first. Understanding that conversion up front helps you know exactly what to aim for.

Quick answer: CLB is a 1–12 scale IRCC uses for every accepted test. CELPIP maps to it directly (CELPIP 7 = CLB 7). IELTS and PTE Core each use their own conversion table, and the required band can differ slightly by skill.

What CLB actually measures

The Canadian Language Benchmark is Canada's standardized scale for describing English (and, as NCLC, French) ability across four skills: listening, reading, writing, and speaking. It runs from CLB 1 (very basic) to CLB 12 (near-native), and different immigration programs set different minimum CLB requirements — often a different minimum for each of the four skills, not just one overall number.

How each test converts

TestHow conversion works
CELPIPDirect 1:1 — a CELPIP score of 7 in a skill simply equals CLB 7 in that skill.
IELTSEach band score maps to a CLB level, but the exact band needed can vary slightly by skill and by CLB level — reaching CLB 7 across the board generally means a 6.0 in every band, though check the current official table for your specific skill.
PTE CoreUses its 10–90 scale converted through IRCC's official PTE Core to CLB table, added when PTE Core became an accepted test.

What CLB level do you actually need?

Because required levels vary by program and change periodically, treat any specific number you read (including in this article) as a starting point to verify, not a final answer.
