IELTS band scores explained: what each band means and how it is calculated

One scale from 0 to 9

IELTS does not have a pass mark. Everyone who takes it receives a band score that describes how well they use English, from band 1 for a non-user to band 9 for an expert user. Band 0 is kept for one case only: a candidate who did not attempt the test. So if you sit IELTS and answer the questions, your result always says something about your English.

Each band has a short name and a description published by IELTS. The descriptions are worth reading, because they explain what organizations have in mind when they ask for a score. A university that asks for 7 is asking for someone who handles complex language well despite occasional mistakes; an organization that asks for 6 wants effective command of English in familiar situations, with some errors and misunderstandings.

The same scale is used for each of the four skills and for the overall result. That is why requirements can be so precise: an organization can ask for an overall 6.5 and also set a minimum for one skill, for example no less than 6 in Writing.

How the overall band is calculated

The overall band is the average of your four skill bands, rounded to the nearest whole or half band. Add the four results, divide by four, and look at what is left after the decimal point. In most cases the rounding is obvious: an average of 6.1 becomes 6, and an average of 6.4 becomes 6.5.

The question everyone asks is what happens exactly halfway, and IELTS answers it directly. If the average ends in .25, it is rounded up to the next half band. If it ends in .75, it is rounded up to the next whole band. A candidate with an average of 6.25 therefore gets 6.5 overall, and one with 3.875 gets 4. An average of 6.125, on the other hand, is closer to 6 than to 6.5, so it is rounded down to 6. These three cases are the worked examples IELTS itself publishes.

Listening and Reading: from marks to bands

The Listening and Reading tests each have 40 questions, and each correct answer is worth one mark. There are no half marks: your raw score is simply the number of correct answers, and that mark out of 40 is then converted into a band.

IELTS publishes approximate figures for the most common bands, and they are useful to know when you practice. IELTS points out that the precise number of marks needed for each band varies slightly from one version of the test to another, so treat the figures below as a guide, not as a promise.

Look at the last column. The same band needs more correct answers in General Training Reading than in Academic Reading: about 30 marks for band 6, where Academic needs about 23. The bands mean the same level of reading ability in both versions; the conversion simply reflects that the two tests use different texts. It also means that a practice score from one version cannot be converted with the table of the other.

For Listening, the table gives you a practical target. Moving from band 6 to band 7 takes roughly seven more correct answers, from about 23 to about 30. Seen like that, half a band is a handful of questions, often lost to spelling, to a missed plural or to an answer written in the wrong place.

Writing: four criteria, two tasks

Writing is marked by trained examiners, not by a count of correct answers. Each of the two tasks is assessed on its own against four criteria that carry equal weight, and the task score is the average of the four. The Writing band then combines the two tasks, and Task 2 carries more weight than Task 1, so the essay counts for more than the shorter first task.

Task achievement and task response

The first criterion asks whether you did what the task asked. In Task 1 it is called Task achievement, and in Task 2 Task response. An essay can be fluent and still score low here if it does not answer every part of the question, wanders away from the topic or never makes its position clear.

Coherence and cohesion

This criterion looks at how your text is organized. Ideas should follow a logical order, paragraphs should each have a clear purpose, and linking words such as however, as a result and on the other hand should connect ideas rather than decorate the text.

Lexical resource

Lexical resource is your vocabulary: its range, its precision and how naturally you combine words. Rare words help only when they are used correctly. A precise everyday phrase such as a sharp rise in prices often does more than an impressive word in the wrong place.

Grammatical range and accuracy

The last criterion rewards a variety of sentence structures used accurately. Short, correct sentences keep you safe but limit the score; complex sentences with frequent errors pull it down. The goal is a mix of both, with errors that do not get in the way of meaning.

Speaking: four more criteria

The Speaking test is a conversation with an examiner, and it is marked on four criteria of equal weight as well. Three of them will sound familiar: fluency and coherence, lexical resource, and grammatical range and accuracy. The fourth is pronunciation.

Fluency and coherence is about speaking at length without long pauses, and about linking your ideas so the listener can follow them. Pronunciation is not about sounding British or American. It is about being easy to understand: in the public band descriptions, a speaker at band 8 is easy to understand throughout, and their first-language accent has only a minimal effect on how clear they are.

Half a band is often a handful of questions.

Academic or General Training: same scale, different tests

IELTS comes in two versions. Listening and Speaking are the same in both; Reading and Writing are different. IELTS Academic is for study at university level, and General Training is for people who want to migrate to an English-speaking country or to train or study below degree level.

Both versions report on the same 0 to 9 scale, and the overall band is calculated in the same way. What matters is that you take the version the organization asks for. A band 7 in General Training is not a band 7 in Academic for an application that names Academic. If you are still choosing between IELTS and another exam altogether, our comparison of IELTS and Cambridge English covers that decision.

What score will you be asked for?

Every organization sets its own requirement. Universities usually publish an overall band and a minimum for each skill, and the numbers often differ from course to course within the same university. Professional bodies and employers set their own targets too. The only reliable figure is the one on the official page of the place you are applying to, so read it closely, including whether it asks for Academic or General Training.

Pay attention to the wording. “Overall 6.5 with no less than 6 in any component” means four results of at least 6 and an average that rounds to 6.5. “6.5 in each skill” is a much harder target, because every single band has to reach 6.5.

UK visas: SELT and IELTS for UKVI

For many UK visas, the Home Office asks for a Secure English Language Test, or SELT. The UK government lists IELTS for UKVI and IELTS Life Skills as the IELTS tests approved for this purpose, and they must be taken at an approved test center. The required CEFR level depends on the visa route, and the UK government requires the minimum score in every component of the test, not just overall.

IELTS Life Skills works differently. It tests only Speaking and Listening, at A1, A2 or B1, and the result is a pass or fail rather than a band. It is used for routes such as family visas and settlement, where only speaking and listening are required.

IELTS and the CEFR

Many organizations, especially in Europe, describe language levels with the CEFR, from A1 to C2. IELTS has been mapped to the CEFR, but the bands were never designed to line up exactly with the CEFR levels, and IELTS recommends that organizations use the band descriptions themselves when setting requirements.

What IELTS does say is this. Band scores of 8.5 and higher are recognized as C2, with band 8 on the border. The step into C1 falls between bands 6.5 and 7: many candidates with 6.5 are at C1, some are just below it, so an organization that wants to be sure of C1 may ask for 7. Band 5 is given as an example of a border score, where a candidate may be B1 or B2. For UK visas, the table above shows the minimum results the UK government accepts for B1, B2 and C1.

How long is a result valid?

IELTS results are officially recognized as valid for two years from the test date. The Test Report Form cannot be extended or revalidated, so if you need a result after that, you take the test again. Some organizations set a different window, which is why the IELTS partners advise checking with the institution first.

UK visa rules use the same two years in their own way: a SELT result is valid for two years from the date it is awarded, and it must have been awarded in the two years before the date of your application. Plan the timing so that your result is still valid when you apply, not only when you book.

IELTS One Skill Retake

If one skill keeps your overall band below the target, you may not need to take the whole test again. IELTS One Skill Retake lets you retake one of the four skills, Listening, Reading, Writing or Speaking, within 60 days of a full IELTS test taken on computer at a test center. It is available for both Academic and General Training, but not after a paper-based test or IELTS Online, and you can use it only once for each full test.

You receive a new Test Report Form that shows the retaken score, marked as a retake, together with your original results in the other three skills, and the overall band is recalculated. Your original Test Report Form stays valid, so you can use whichever result is better. The catch is acceptance: organizations have to opt in, and not all of them accept a retake. Ask the place you are applying to before you book.

How to move up half a band

Start with the arithmetic. Find out which skill sits furthest below the requirement, then work out what the overall band needs. Because each skill is a quarter of the average, one weak skill pulls the overall band down more than most people expect, and one improved skill can lift it.

Listening and Reading

In the receptive skills, half a band is a few more correct answers. Check every answer for spelling, since a misspelled answer is marked as incorrect, follow the word limit in the instructions exactly, and never leave a question blank: only correct answers earn marks, so a blank can never help you. In Reading, practice with the version you will actually take, because the mark needed for each band differs between Academic and General Training.

Writing

Since Task 2 carries more weight, give it the time it needs. Plan for a few minutes before you write, answer every part of the question, and make your position clear from the start. Write at least the minimum length, 150 words for Task 1 and 250 for Task 2. Then check your work against the four criteria: an essay with good grammar but an incomplete answer to the question will stay stuck.

Speaking

Extend your answers with a reason, an example or a contrast, use the tenses naturally, and keep talking when you are looking for a word, rephrasing instead of stopping. Record yourself and listen back: pauses, repeated words and unclear sounds are much easier to hear from the outside.

Real progress takes regular practice with feedback, not only more tests. At Alimun you learn in live classes with a teacher and the same small group, and your teacher corrects your homework, so you know which criterion is holding your writing back. Not sure where you are starting from? The level test places you from A1 to C1 in a few minutes.
