Quick answer: The IELTS band scale runs from 0 to 9, where each whole band describes a level of English - from band 1 (non-user) up to band 9 (expert user) - and 0 means you did not attempt the test. Scores are reported in half-band steps (for example 6.0, 6.5, 7.0), you receive a separate band for each of the four skills, and those four bands are averaged into a single overall band. This article explains what each band means, why half bands exist, and how the four skills combine.

The nine bands, from 0 to 9
Every IELTS score sits on a single nine-point scale. Each band has an official description of what a test taker at that level can do. In plain English:
- Band 9 - Expert user. Complete command of English: fluent, accurate and natural.
- Band 8 - Very good user. Handles the language well, with only occasional slips and the odd unfamiliar situation causing trouble.
- Band 7 - Good user. Operational command with occasional inaccuracies; handles complex language well.
- Band 6 - Competent user. Generally effective English despite some inaccuracies, especially in familiar situations.
- Band 5 - Modest user. Partial command; copes with overall meaning in most situations but makes many mistakes.
- Band 4 - Limited user. Basic competence limited to familiar situations; struggles with complex language.
- Band 3 - Extremely limited user. Conveys and understands only general meaning in very familiar situations.
- Band 2 - Intermittent user. Great difficulty understanding spoken and written English.
- Band 1 - Non-user. Essentially no ability beyond a few isolated words.
- Band 0 - Did not attempt. No assessable information; the test was not attempted.
Most people who need IELTS for study, work or migration sit somewhere in the band 5 to band 8 range, and small differences at that level matter a great deal to the institutions reading your score.
Why IELTS uses half bands
A jump of one whole band is a big leap in ability, so IELTS reports in half-band increments - 5.5, 6.5, 7.5 and so on. Half bands give institutions a finer distinction: a candidate at "a solid 6, edging towards 7" can be reported as a 6.5 rather than being squeezed into either neighbouring whole band. This matters because a university or visa route might set its cut-off precisely at a half band, such as "6.5 overall with no skill below 6.0".
Half bands apply to your individual skill scores and to the overall band. In Listening and Reading, your raw number of correct answers is converted to a band that can itself be a half band; in Writing and Speaking, examiners award bands against detailed criteria.
Four skills, four separate bands
IELTS tests four skills, and each produces its own band:
- Listening and Reading are marked objectively from your correct answers, then converted to a band using a fixed table. (Academic and General Training Reading use slightly different conversions, because the texts differ.)
- Writing and Speaking are marked by trained examiners against four published criteria each, and the criteria are weighted equally within that skill.
Because each skill is reported separately, your strengths and weaknesses are visible. You might be a confident reader but a hesitant speaker, and your report will show that - which is why so many institutions set a minimum in every skill rather than looking only at the overall figure.
How the four skills become one overall band
Your Overall Band Score is simply the average of your four skill bands, rounded to the nearest half band. Two quirks of the rounding are worth knowing: an average ending in .25 rounds up to the next half band, and one ending in .75 rounds up to the next whole band. So an average of 6.25 becomes 6.5, and an average of 6.75 becomes 7.0.
Here is a quick illustration using original numbers:
- Listening 7.0, Reading 6.5, Writing 6.0, Speaking 6.5 → average 6.5 → overall 6.5.
- Listening 6.5, Reading 6.5, Writing 5.5, Speaking 6.0 → average 6.125 → rounds to overall 6.0.
- Listening 7.0, Reading 7.0, Writing 6.5, Speaking 6.5 → average 6.75 → rounds up to overall 7.0.

What the scale does not tell you
A band describes your English level, but it does not decide whether you have "passed" - there is no pass mark in IELTS. Whether your band is high enough is entirely up to the university, employer or immigration authority receiving it. So the scale is only half the picture; the other half is knowing the exact requirement for your goal, which we cover in the rest of this band-scores guide.

Finally, a word on where this can lead: once your English is strong enough to hit your target band, that same fluency opens doors. Many of our readers go on to train to teach English abroad with an accredited TEFL/TESOL course, turning a hard-won IELTS score into a career overseas.
