Canada CLB / NCLC Language Score Converter

Why your test score is not the number Canada uses

IELTS reports a band from 0 to 9 in half-point steps. CELPIP reports a level from 1 to 12. TEF Canada reports points out of 450, 360 and 300 depending on the ability. TCF Canada reports a mix of small whole numbers out of 20 and larger figures out of 699. None of those scales is what Immigration, Refugees and Citizenship Canada actually uses to decide whether you qualify.

IRCC measures English with the Canadian Language Benchmarks, or CLB, and French with the Niveaux de competence linguistique canadiens, or NCLC. Both run from 1 to 12. When you build an Express Entry profile, the system wants a CLB or NCLC level for speaking, listening, reading and writing separately. Your test certificate carries the raw score; IRCC's equivalence chart turns that raw score into a benchmark level; the Comprehensive Ranking System then turns the benchmark level into points.

That is three conversions stacked on top of each other, and each one is a place where people lose points without noticing. The most common failure is reading the wrong column on a French test report. The second most common is assuming a strong average carries a weak ability. This page does the arithmetic for you and shows the intermediate steps so you can check them against your own certificate.

One point about cost that catches people out: IRCC does not charge a separate fee for assessing your language result. The cost sits entirely with the test provider, and it differs by country and by test, so check the provider's current price rather than budgeting from a figure quoted on a third-party site. There is no cheaper approved route, and a cheaper unapproved test will not be accepted however well you score.

What do you type in, and what comes out?

The converter takes one test type and four numbers. Pick the test from the first dropdown, then enter your speaking, listening, reading and writing results exactly as they appear in the ability table of your report. Order matters: speaking and listening come first because that is how IRCC prints its charts, and swapping them is a quiet way to get the wrong answer.

What comes out is a block with five parts. First, the CLB or NCLC level for each of the four abilities. Second, your lowest ability, which is the number that decides whether you clear a program minimum. Third, a plain average of the four levels, clearly labelled as not an IRCC figure. Fourth and fifth, the CRS core points your first official language earns with a spouse or common-law partner, and without one, because those two columns pay differently from CLB 6 upward.

The inputs follow each test's real scale. IELTS accepts half bands between 0 and 9. CELPIP accepts whole numbers from 1 to 12. TEF Canada caps at 450 for speaking and writing, 360 for listening and 300 for reading. TCF Canada caps at 20 for speaking and writing, and 699 for listening and reading. If you enter something outside those ranges the converter says so instead of quietly rounding it.

Why four abilities become four different levels

IRCC does not average your test result. It converts each ability on its own and keeps four separate levels. A candidate who scores IELTS 7.0 in reading but 5.5 in writing holds CLB 9 for reading and CLB 6 for writing at the same time, and both are true.

This matters twice. It matters for points, because the CRS pays per ability, so the strong reading score earns its full share even though writing lags. It matters more for eligibility, because every Express Entry program sets a minimum that must be met in every ability. The Federal Skilled Worker Program wants CLB 7 across all four. A single CLB 6 ability fails the program no matter how high the other three climb.

For that reason the converter leads with your lowest ability rather than an average. An average of CLB 8 sounds reassuring and tells you nothing about whether you qualify. The weakest ability is the one that will decide your outcome, and it is the one worth fixing first if you are planning a retake.

IELTS General Training to CLB

IRCC accepts the IELTS General Training option only. The Academic module is not accepted for Express Entry, and IRCC states plainly that it does not accept IELTS One Skill Retake. If you improved one ability through a retake of a single skill, that result cannot be used. You need a full test report form.

The chart below reproduces IRCC's IELTS equivalency for CLB 4 through CLB 10 and above. Note the shape of it: from CLB 4 to CLB 9 each cell holds a single band, and only the top row shows ranges.

The reading column is the one that surprises people. CLB 7 in reading needs 6.0, while CLB 6 needs only 5.0, so a band of 5.5 lands in CLB 6 and earns 8 points with a spouse rather than 16. Listening has the widest jump of any ability: CLB 7 needs 6.0 and CLB 8 needs 7.5, a full band and a half apart.

CLB 10 and above is worth the same as CLB 9 in some places and more in others. On the CRS core table, CLB 9 pays 29 points with a spouse and CLB 10 pays 32, so pushing from band 7.0 to 7.5 in speaking is worth 3 points on that ability alone.

CELPIP-General to CLB

CELPIP is the simplest of the four because IRCC's chart prints the same number in the CELPIP column as in the CLB column. A CELPIP speaking score of 8 is CLB 8. There is no lookup table to memorise and nothing to interpolate.

The two conditions are that you must take CELPIP-General, not CELPIP-General LS, and that the conversion tops out at CLB 10. IRCC's chart reads "10 and above" for the top row, so CELPIP 10, 11 and 12 all sit in that band and all earn the CLB 10 rate.

Because the CELPIP scale is already a benchmark scale, it is the only one of the four where a score cannot be misread from the wrong column. That is a real advantage if you are choosing a test and your main worry is administrative error rather than test format.

TEF Canada to NCLC, and the 699 trap

TEF Canada is where most French-speaking applicants lose points they had already earned. IRCC's instructions on the language test page say that your level is based on the column headed "Equivalence ancien score" and then warn, in bold, that your attestation de resultats will also include a column marked "Score / 699" which must not be entered into your profile because those figures are not compatible with the system. The same page states that entering the wrong scores can lead to a refusal.

IRCC also notes that CCI Paris Ile-de-France briefly modified the NCLC mapping to reflect raw scores for tests taken between 11 December 2023 and 6 May 2024, and that the change has since been reverted to the scoring grid in current use. The equivalence table published for that window is identical to the current one, so a single table covers every valid TEF Canada result.

The ranges here are contiguous, unlike the IELTS cells. Every possible score between the NCLC 4 floor and the top of each ability falls inside a band, so there is nothing for this converter to interpolate. The only judgement call is at the very bottom, where a score under the NCLC 4 figure has no published band at all.

One more detail from IRCC's page: your TEF Canada electronic results already include "the NCLC equivalence level you achieved for each test component". If that line is printed on your report, it is the authoritative figure and you should compare it with this converter rather than trusting either one alone.

TCF Canada to NCLC

TCF Canada uses two different scales inside one report. Speaking and writing are scored out of 20. Listening and reading are scored out of 699. The NCLC cut-offs are correspondingly different per ability, and listening and reading do not share the same numbers, which is the single most common source of error with this test.

Look at 523 on the listening scale and 523 on the reading scale. In listening, 523 is the first score in NCLC 9. In reading, 523 is the last score in NCLC 8, because NCLC 9 reading starts at 524. Two abilities, one number, two different levels. A converter that applies a single TCF scale to all four abilities will be wrong for anybody sitting on that boundary.

The speaking and writing scales have a different trap. They run in small whole numbers, so a single point moves you a whole band: 15 is NCLC 9, 16 is NCLC 10, and there is no half-step between them. Being one point short of the next band is still a whole band short, not a near miss.

Where IRCC's chart leaves a gap

Three of the four tests have fully contiguous cut-offs once written as ranges. IELTS does not, because IELTS reports half bands and IRCC's chart prints single values for CLB 4 through CLB 9. Reading the listening column straight down gives minima of 4.5, 5.0, 5.5, 6.0 and then a jump to 7.5. The bands 6.5 and 7.0 do not appear anywhere on the chart.

Rather than invent a band, this page states the rule it applies and lets you see whether it affects you. The rule is that a score takes the highest level whose printed minimum it meets. So a listening band of 7.0 meets the CLB 7 minimum of 6.0 and does not meet the CLB 8 minimum of 7.5, and is therefore treated as CLB 7.

The same gap logic applies in three other places on the IELTS chart. Speaking and writing both jump from a CLB 4 minimum of 4.0 straight to a CLB 5 minimum of 5.0, which leaves 4.5 with no printed row. Reading jumps from 4.0 to 5.0 and then from 5.0 to 6.0, leaving both 4.5 and 5.5 unlisted. In each case the converter awards the lower level, because the higher level's printed minimum has not been met.

Two other gaps are worth naming. CELPIP 11 and 12 have no dedicated row because IRCC stops at "10 and above", so this converter scores them in the CLB 10 band rather than pretending to know a CLB 11 rate that IRCC does not publish. And IRCC publishes no overall CLB figure at all, so any single number claiming to be your "overall level" is a derived figure rather than an official one.

How CRS language points follow from CLB

Once you hold a CLB or NCLC level, the Comprehensive Ranking System pays points for your first official language ability by ability. The table below is IRCC's core human capital language table, and it is the one this converter uses.

The two columns are identical up to CLB 5 and diverge from CLB 6. That divergence is why a candidate with a spouse can sit at the same benchmark level as a single candidate and score four to eight points lower overall. The maximum of 128 with a spouse and 136 without comes from multiplying the top per-ability figure by four.

Three other language-related point pools sit outside that table. A second official language earns 0 for CLB 4 or less, 1 for CLB 5 or 6, 3 for CLB 7 or 8 and 6 for CLB 9 or more, per ability. French language skills add 25 points where you hold NCLC 7 or higher on all four French abilities and CLB 4 or lower in English, or 50 points where you hold NCLC 7 or higher on all four French abilities and CLB 5 or higher on all four English abilities. Skill transferability adds up to 25 points where you hold CLB 7 or more on all four first-language abilities with at least one below CLB 9, and up to 50 where all four are CLB 9 or more, combined with a post-secondary degree, foreign work experience or a certificate of qualification.

One point of housekeeping on the second-language pool: IRCC's table prints a section maximum of 22 points with a spouse or common-law partner and 24 without, while the per-ability figures above add to 24 in both cases. The per-ability values are what the calculator applies and what your profile uses. If that discrepancy matters to your total, check your profile output against the CRS criteria page directly rather than relying on any summary.

IRCC has also published a change taking effect on 3 November 2026 that alters how points are awarded for Canadian work experience and valid job offers, and removes the Labour Market Impact Assessment requirement for job offers. IRCC says existing profiles will be recalculated, that the recalculation could take up to two weeks, and that invitation rounds will pause while it runs. Language points are not part of that change, but a recalculation can still move your ranking position against other candidates while your language score stays fixed.

What CLB each program needs

Points decide your rank. Minimums decide whether your profile enters the pool at all. The two are separate checks and a high CRS total does not rescue a failed minimum.

The Federal Skilled Trades Program is the only one of the three that sets different minimums for different abilities, which makes a per-ability converter genuinely necessary rather than convenient. Speaking and listening need CLB 5 while reading and writing need CLB 4. A trades applicant with strong spoken English and weak reading can qualify where a Federal Skilled Worker applicant with the same scores cannot.

These minimums are gates, not scores. If you cannot clear the required level in all four abilities, you are not eligible for that program, and a high CRS total does not change that outcome. The only fix is a higher test result in the ability that falls short.

Eligibility for these programs is assessed separately from the points. If you are still deciding which program fits, the Express Entry eligibility guide walks through the work experience and education conditions that sit alongside the language minimums.

Below CLB 4: the floor

IRCC's equivalence charts stop at CLB 4 for every test. There is no published row for CLB 3, CLB 2 or CLB 1 on the Express Entry charts, and the CRS table pays zero for anything under CLB 4. So a score beneath the CLB 4 minimum does not become CLB 3 in any usable sense. For Express Entry purposes it is simply a zero.

This converter says "below CLB 4" rather than assigning a level. That is deliberate. Guessing at CLB 3 would be inventing a mapping IRCC does not publish, and it would mislead you about how much ground a retake has to cover.

The practical consequence depends on the ability. A below-floor reading score of 3.0 on IELTS sits under the CLB 4 minimum of 3.5, so it earns nothing and it also fails the Federal Skilled Trades Program reading minimum of CLB 4. The same candidate with 3.5 in reading would hold CLB 4, earn 6 points with a spouse for that ability and clear the trades minimum. Half a band moves the answer from zero to useful.

If you are below the floor in more than one ability, the realistic route is a retake rather than a profile. A profile that cannot meet a program minimum will not receive an invitation however long it sits in the pool, because the minimum is a gate rather than a score.

Six worked conversions

Each line below was run through the same function that powers the calculator above, so you can check the tool against the arithmetic.

1. IELTS 6.0 in all four. Speaking, listening, reading and writing each land exactly on the CLB 7 minimum. Four abilities at CLB 7 gives 64 points with a spouse and 68 without. This is the floor case for the Federal Skilled Worker Program and the most common starting point.
2. IELTS with listening at 7.5 and the rest at 6.0. Listening clears the CLB 8 minimum of 7.5, so it rises to CLB 8 while the other three stay at CLB 7. That is 70 points with a spouse and 74 without, a gain of 6 points from one ability.
3. CELPIP 8 in all four. Because the score is the level, all four sit at CLB 8, worth 88 points with a spouse and 92 without. Nothing is lost to conversion here.
4. TEF Canada speaking 393, listening 316, reading 263, writing 393. Each of those figures is the exact NCLC 10 minimum for its ability, so all four reach NCLC 10 and the total is the maximum 128 with a spouse or 136 without. Drop speaking by a single point to 392 and that ability falls to NCLC 9, taking the total to 125 or 133.
5. TCF Canada speaking 16, listening 549, reading 549, writing 16. Again all four sit exactly on the NCLC 10 minimum, giving the maximum 128 or 136. The same result as the TEF line above, from a completely different scale.
6. IELTS speaking 6.0, listening 6.0, reading 3.0, writing 4.0. Speaking and listening reach CLB 7, writing reaches CLB 4 and reading falls below the floor at zero. The total is 38 with a spouse and 40 without, and the profile fails every Express Entry program because reading does not meet any minimum.

Note what the last example shows. Three abilities producing 38 points looks like a profile worth submitting, and it is not, because the reading line is a zero rather than a low score. Points and eligibility have to be checked separately.

What usually goes wrong with these numbers

1. Reading the TEF out-of-699 column. This is the single most damaging error on the page. IRCC's language test instructions warn that entering those figures can lead to a refusal. Use the per-ability equivalence column.
2. Using TCF reading cut-offs for the listening score. The two scales differ by a point around NCLC 8 and 9, so 523 is NCLC 9 in listening and NCLC 8 in reading.
3. Assuming CELPIP 11 or 12 pays more than CELPIP 10. IRCC stops itemising at CLB 10, so the top three CELPIP scores earn the same points.
4. Swapping speaking and listening when typing results in. Both are out of the same scale on every test, so the error produces a plausible-looking answer that is wrong.
5. Averaging four abilities instead of checking the weakest. Averages are not part of IRCC's method at either the points stage or the eligibility stage.
6. Using an IELTS One Skill Retake. IRCC does not accept it for Express Entry, so the improved single-skill result cannot be used.

What to do next

1. Start by checking the column heading on your report before you enter anything. For French tests especially, confirm you are reading per-ability equivalence scores rather than a total out of 699.
2. Keep the result document itself. The document you were issued — the IELTS test report form, the CELPIP score report, or the TEF or TCF attestation — is what IRCC checks your profile against. Store the original, and confirm the reference number on the document matches the one you entered.
3. Confirm your level in your IRCC account once you have created a profile. The system assigns a level and shows it to you, and that assignment outranks any calculator, including this one.
4. Check your CRS total against draw history using the CRS draw predictor, which compares your score with recent invitation rounds rather than with a single threshold.
5. Check the result's age. It must be under 24 months old both when you build the profile and when you submit the permanent residence application.
6. Price the rest of the application with the proof of funds guide and the settlement funds calculator, because language points do not change the funds requirement.
