ScoreFluentLanguageCert to IELTS: the official conversion.
LanguageCert published a concordance study with IELTS Academic in October 2024 — 1,008 test takers who sat both exams, equipercentile linking, overall correlation .87. These are its published equivalences, reproduced with the sample size and standard error behind every row, because those are what tell you which rows to trust.
Overall equivalences.
| IELTS Academic | LanguageCert Academic | Students at this level | Standard error |
|---|---|---|---|
| 4.5 | 38–45 | 27 | 1.56 |
| 5.0 | 46–53 | 74 | 0.79 |
| 5.5 | 54–60 | 185 | 0.43 |
| 6.0 | 61–66 | 225 | 0.40 |
| 6.5 | 67–72 | 189 | 0.46 |
| 7.0 | 73–80 | 148 | 0.47 |
| 7.5 | 81–87 | 104 | 0.59 |
| 8.0 | 88–94 | 42 | 0.78 |
| 8.5 | 95+ | 3 | 4.84 |
| 9.0 | no equivalent published | 0 | — |
The standard error here is the standard deviation of LanguageCert scores at each IELTS half band divided by the square root of the sample at that band. It describes how well-supported the linking is — it is not a margin of error on your own score.
Where the conversion stops being reliable.
There is no IELTS 9.0 equivalent
Not one of the 1,008 candidates scored IELTS 9.0, so the report publishes no LanguageCert range for it. Any chart that shows one has made it up.
The top of the scale rests on a handful of people
IELTS 8.5 overall is based on 3 students, with a standard error of 4.84 — several times any other row. For Writing it is worse: IELTS 8.0 rests on 2 students and 8.5 on one. Above roughly 88 in Writing, treat the comparison as beyond the published range.
Per-skill is much weaker than overall
Overall correlates at .87; per skill it is .71 to .76, with standard errors two to three times larger. Use the overall equivalent as the number that means something and per-skill only as a rough band.
A concordance is not an exchange rate
The study states it plainly: scores linked through concordancing are not expected to be interchangeable. It also finds LanguageCert more demanding than IELTS in the computer-marked skills.
The mapping shifts between groups
The report tests population invariance and finds the alignment moves by several points between nationality and gender subgroups — a LanguageCert 88 can sit either side of an IELTS band boundary depending on which subgroup table you read.
Your institution decides, not this table
Universities and visa streams state which tests they accept and at what score. A conversion is useful for setting a target while you study. It is not evidence of eligibility.
Skill-by-skill equivalences.
Note how differently the four skills behave — LanguageCert Speaking sits well above the others against the same IELTS band, and Writing compresses hard at the top.
| IELTS | Listening | Reading | Writing | Speaking |
|---|---|---|---|---|
| 4.5 | 35–40 | 36–43 | 33–44 | 44–53 |
| 5.0 | 41–48 | 44–53 | 45–55 | 54–61 |
| 5.5 | 49–56 | 54–59 | 56–63 | 62–69 |
| 6.0 | 57–61 | 60–64 | 64–70 | 70–75 |
| 6.5 | 62–66 | 65–70 | 71–77 | 76–81 |
| 7.0 | 67–72 | 71–76 | 78–83 | 82–86 |
| 7.5 | 73–79 | 77–82 | 84–88 | 87–88 |
| 8.0 | 80–88 | 83–88 | 89–92 | 89–92 |
| 8.5 | 89–94 | 89–96 | 93+ | 93–98 |
| 9.0 | 95–100 | 97–100 | none | 99–100 |

Conversion questions, answered.
What is my IELTS equivalent for a LanguageCert Academic score?
At overall level the official concordance maps LanguageCert 61–66 to IELTS 6.0, 67–72 to IELTS 6.5, 73–80 to IELTS 7.0, 81–87 to IELTS 7.5 and 88–94 to IELTS 8.0. These come from LanguageCert’s own concordance study of 1,008 test takers who sat both exams, with an overall correlation of .87.
Is a LanguageCert score officially accepted instead of IELTS?
That is the receiving institution’s decision, not something a conversion table settles. LanguageCert Academic is Ofqual-regulated, a UKVI-approved Secure English Language Test and accepted by the Australian Department of Home Affairs for tests taken on or after 7 August 2025. But a university or visa stream states which tests it accepts and at what score — check that requirement directly rather than converting a score yourself.
Why does this table show sample sizes and standard errors?
Because they decide how much a row is worth. IELTS 6.0 rests on 225 students; IELTS 8.5 rests on 3, with a standard error of 4.84. Most conversion charts drop those columns and present every row as equally solid, which is exactly where they mislead. A wide range at the top of the scale is not precision you can plan around.
Is there a LanguageCert equivalent of IELTS 9.0?
No. Nobody in the 1,008-candidate study scored IELTS 9.0, so the report publishes no equivalent for it and marks the row not applicable. Any chart showing a LanguageCert score for IELTS 9.0 has invented it.
Are the two scores interchangeable?
No, and the study says so directly: scores linked through concordancing are not expected to be interchangeable. A concordance is a statistical alignment of two different tests measuring overlapping things, not an exchange rate. The report also notes LanguageCert appears more demanding in the objectively marked skills — Listening and Reading — than IELTS.
How reliable is the per-skill conversion compared with the overall one?
Less reliable. The overall correlation is .87, but per skill it is .76 for Reading and .71 for Writing, Listening and Speaking, and the standard errors on the per-skill tables run two to three times those on the overall table. Treat a per-skill equivalent as a wide range and the overall figure as the meaningful number.
