Preparing your language test: IELTS, CELPIP, TEF, TCF
Language scores are the single easiest way to move your CRS. A quick guide to the four IRCC-designated tests and how their scores convert to CLB or NCLC levels.

For economic immigration, IRCC accepts four tests: IELTS General Training and CELPIP-General for English, and TEF Canada and TCF Canada for French. Each is scored across four abilities — reading, writing, listening, speaking — and each ability is converted to a Canadian Language Benchmark (CLB, English) or Niveau de compétence linguistique canadien (NCLC, French) level.
Why the CLB step matters
CRS points are awarded by CLB level, not by the raw test score. Moving from CLB 7 to CLB 9 across all four abilities can add well over fifty points to a single applicant's core score, plus meaningful transferability bonuses. That is often a larger jump than a year of additional work experience.
Choosing a test
- IELTS General Training — paper or computer-based, widely available, familiar to most candidates.
- CELPIP-General — fully computer-based, designed in Canada, and scored on a scale that maps 1:1 to CLB.
- TEF Canada or TCF Canada — required if you want to claim French-language points, including the French-language category-based draws.
Practical preparation
- Take one full timed practice test before you register. It usually decides which test suits you.
- Weakest ability sets your language score for transferability — target it first.
- Book the test roughly six to eight weeks out, so results arrive in time to build your Express Entry profile.
