What is a good IELTS score? We enumerated all 130,321 of them

“Is 7.0 a good score?” is the most asked question about this exam, and it has no answer in that form. Not because the answer is complicated, but because the question is about the wrong number.

What is a good IELTS score?

A good IELTS score is one where your weakest skill clears the bar set by the specific institution you are applying to. The overall band — the number everyone quotes — is an average, and averages conceal exactly the information that admissions officers and regulators are looking for.

We can show this precisely rather than assert it, because the IELTS scoring space is finite and can be enumerated completely.

How many different IELTS results are there?

Four skills, each scored in half-point steps from 0 to 9. That is nineteen possible values per skill, and nineteen to the fourth power — 130,321 distinct score reports. Every IELTS result that has ever been issued or ever will be is one of these.

The overall band is then the average of the four, rounded by a rule IELTS publishes:

The overall band score is the average of the four section band scores rounded to the nearest half band.

If the average of the four sections ends in .25, the overall band score is rounded up to the next half band, and if it ends in .75, the overall band score is rounded up to the next whole band.

We applied that rule to all 130,321 reports. Here is how they distribute:

Two observations. High bands are mathematically scarce — there are only fifteen ways to be a 9.0, and 1,213 times more ways to be a 4.5. And the middle of the scale is crowded, because averaging four numbers pulls results toward the centre.

Why does the overall band hide what institutions look at?

Here is the finding that should change how you read your own score report.

4,255 different score reports produce an overall band of exactly 7.0. They include profiles as lopsided as 0.0 in one skill and 9.0 in three others. Every one of those candidates gets a certificate saying 7.0.

Now apply a real requirement. The UK’s Nursing and Midwifery Council requires, in its registration guidance updated June 2023, “at least 7 in reading, listening and speaking, and at least 6.5 in writing”.

Of the 4,255 score reports that give an overall 7.0, exactly 15 satisfy those floors. That is 0.4 per cent.

Put plainly: if you know only that a candidate scored 7.0 overall, and you had to bet on whether they qualify to register as a nurse in the UK, you would be wrong 99.6 per cent of the time.

It does not resolve at higher scores either:

Even at an overall 8.0 — a score most people would call excellent — more than half of the possible score reports still fail. Because you can reach an 8.0 with a 6.0 in writing, and a 6.0 in writing is below the floor.

What does a good score mean in the three common situations?

For a university standard offer. Typically 6.5 overall with 6.0 in each skill. The overall part is the easy half: of the 7,495 reports that give exactly 6.5, only 121 also clear 6.0 everywhere — 1.6 per cent. Your risk is not the average, it is your worst paper.

For professional registration. There is usually no overall requirement at all — only per-skill floors. This catches people out badly, and we cover the nursing case in detail in IELTS for nurses.

For a personal benchmark. If nobody is judging you, use the CEFR alignment: bands 7–7.5 align with C1, 5.5–6.5 with B2, 4–5 with B1. The full official table is in IELTS to CEFR. For an honest self-assessment, read the level your lowest skill lands in.

How lopsided can a passing score actually be?

For each overall band, we found the most extreme score report that still produces it:

An overall 7.0 is compatible with understanding nothing that is said to you. This is not a realistic candidate profile — nobody writes at 9.0 while listening at 0.0 — but it is the guarantee the overall band gives you, and the answer is that it guarantees very little. Per-skill floors exist because institutions worked this out a long time ago.

So what should you do with your score report?

Three steps, in this order.

Find the actual requirement, per skill, from the institution itself. Not from an agency, not from a forum. The requirement is almost always four numbers, not one.

Compare your weakest skill to its floor. That single comparison decides your application. Your overall band is, for this purpose, decoration.

If you are short, train the weak skill, not the average. Half a band on your worst paper improves both your eligibility and your overall score. Half a band on your best paper improves only the number that was not being read.

And if the weak skill is reading or listening, the honest answer is that it responds to volume more than to technique. Comprehension at C1 comes from having met enough English, repeatedly, slightly above your comfort level — which is the principle the level-by-level pages here are built on, and what Leo exists to make a daily habit rather than a project.

How did we calculate this?

The rounding rule and the band descriptors come from the official IELTS scoring in detail page, checked 29 August 2026. The CEFR alignment comes from the Guide to IELTS scores, 2025 edition, page 12. The nursing requirement is quoted from the NMC’s Guidance on registration language requirements, updated June 2023.

The counts are ours. We enumerated the complete product of nineteen half-point values across four skills — all 130,321 reports — applying the official rounding rule, and computed the results in integer half-points so that the .25 and .75 cases are exact rather than subject to floating-point error. The rounding implementation is verified against six worked cases before the enumeration runs.

Nobody else publishes these numbers, as far as we can tell, because they require doing the calculation rather than repeating the table. If a competitor reproduces this angle, they will have to run it themselves.
