CLB Calculator – Language Test Equivalency Tool | Convert IELTS to CLB, CELPIP to CLB, TEF to NCLC, TCF to NCLC

What is CLB Calculator?

A CLB (Canadian Language Benchmarks) calculator is a tool designed to assess an individual’s English language proficiency, especially for those planning to immigrate to Canada or for educational and professional purposes within Canada. The CLB levels range from 1 to 12, with 12 being the highest level of proficiency. These benchmarks are used to describe language ability in various skills — speaking, listening, reading, and writing.

If you’re looking to calculate your CLB level based on IELTS (International English Language Testing System) scores, CELPIP (Canadian English Language Proficiency Index Program) scores, or scores from another recognized English language test, this calculator can help you approximate your CLB level based on the information you provide from these test scores.

IELTS to CLB

For IELTS to CLB conversions, here’s a rough guide:

  • Listening: Each band (from 4.5 to 9.0) corresponds to a CLB level from 4 to 10.
  • Reading: Each half band (from 3.5 to 8.0) generally aligns with CLB levels 4 to 10.
  • Writing and Speaking: The scores (from 4.0 to 7.5) correspond to CLB levels 4 to 10.

CELPIP to CLB

For CELPIP to CLB conversions, each CELPIP level directly corresponds to a CLB level, as the CELPIP test is calibrated to the CLB standards.

Please provide the scores you wish to convert in our CLB calculator below, and specify whether they’re from IELTS or CELPIP and we can help you determine your CLB level.

PTE to CLB

The PTE (Pearson Test of English) Academic score is another measure of English language proficiency that can be converted to Canadian Language Benchmarks (CLB) for purposes like immigration to Canada. The PTE Academic test assesses listening, reading, speaking, and writing abilities. The scores from the PTE can be mapped to the CLB levels, which range from 1 to 12, with 12 representing the highest proficiency.

The conversion from PTE scores to CLB levels follows a specific pattern, although it’s important to note that these conversions can be approximate and might be subject to change based on Canadian immigration policies or specific program requirements. Here’s a general guide to how PTE scores might map to CLB levels for each skill area:

  • Listening: PTE scores from 28 to 90 map to CLB levels 4 to 10.
  • Reading: PTE scores from 33 to 90 align to CLB levels 4 to 10.
  • Speaking: PTE scores in the range of 42 to 90 generally correspond to CLB levels 4 to 10.
  • Writing: Similarly, PTE scores from 41 to 90 match CLB levels 4 to 10.

These ranges are quite broad, so for a more precise conversion, use your specific PTE scores for each of the skill areas (Listening, Reading, Speaking, and Writing) in the CLB calculator below. With that information, you can convert your PTE Core scores to CLB scores for Canadian Immigration.

What is the NCLC (Niveaux de compétence linguistique canadiens) Calculator?

The NCLC (Niveaux de compétence linguistique canadiens) is the French equivalent of the CLB (Canadian Language Benchmarks) and is used to assess French language proficiency for those looking to immigrate to Canada or for educational and professional purposes within Canada. The NCLC levels range from 1 to 12, with 12 being the highest level of proficiency, and are used to describe language ability in various skills — speaking, listening, reading, and writing.

If you’re looking to calculate your NCLC level based on TEF (Test d’Évaluation de Français) or TCF (Test de Connaissance du Français) this NCLC calculator can help you approximate your NCLC level based on the information you provide from these test scores.

For TEF to NCLC conversions, here’s a general guide:

  • Listening (Compréhension orale): Scores typically range from 145 to 360, corresponding to NCLC levels 4 to 12.
  • Reading (Compréhension écrite): Scores range from 121 to 300, also corresponding to NCLC levels 4 to 12.
  • Writing (Expression écrite): Similar to reading, with scores from 181 to 450 matching NCLC levels 4 to 12.
  • Speaking (Expression orale): Scores from 181 to 450 correspond to NCLC levels 4 to 12.

For TCF to NCLC conversions, it follows a similar pattern, where each band score is aligned with the NCLC levels, but the scoring ranges will differ.

Please provide the scores you wish to convert, specifying whether they’re from TEF or TCF, and we can help you determine your NCLC level.
