IELTS does not give you a percentage or a pass/fail. Instead, every skill gets a band from 1 to 9, and those four bands combine into one overall band. Understanding this scale tells you exactly what to aim for - and stops you wasting effort chasing a "perfect" score you don't actually need.
What the bands mean
Here is the scale in everyday language:
- Band 9 - Expert: fully fluent, accurate, and natural. Like a highly educated native speaker.
- Band 8 - Very good: occasional small slips, but you handle complex language with ease.
- Band 7 - Good: generally accurate; you cope well even if the odd error appears.
- Band 6 - Competent: effective English with some mistakes and misunderstandings.
- Band 5 - Modest: you get your meaning across in familiar situations but make many errors.
- Band 4 - Limited: basic competence limited to familiar situations.
- Bands 1-3: very limited or no real ability to communicate yet.
Most universities ask for 6.0-7.0 overall. Many immigration routes ask for 4.0-6.0. Knowing your target band shapes everything you study.
Half bands exist
Scores move in half steps: …5.0, 5.5, 6.0, 6.5… So your overall band might be 6.5. There is no 6.25 as a final score - only whole and half bands.
How each section is scored
- Listening and Reading are marked out of 40. Your raw score (number correct) is converted to a band using a fixed table. As a rough guide, around 30/40 in Listening sits near band 7.
- Writing and Speaking are judged by a trained examiner against four criteria each (for example, in Speaking: fluency, vocabulary, grammar, and pronunciation). The four criteria are averaged into the band for that skill.
Worked example 1: calculating your overall band
Suppose you score:
| Skill | Band |
|---|---|
| Listening | 6.5 |
| Reading | 6.0 |
| Writing | 5.5 |
| Speaking | 7.0 |
- Add them: 6.5 + 6.0 + 5.5 + 7.0 = 25.0
- Divide by four: 25.0 ÷ 4 = 6.25
- Round to the nearest half band: 6.25 rounds up to 6.5.
The rounding rule is simple: an average ending in .25 rounds up to the next half band, and .75 rounds up to the next whole band. So a 6.25 becomes 6.5, and a 6.75 becomes 7.0.
Worked example 2: how rounding can cost (or save) you
Rounding works in both directions, and the difference of a single point can matter. Compare two candidates aiming for an overall 7.0:
| Skill | Candidate A | Candidate B |
|---|---|---|
| Listening | 7.0 | 7.0 |
| Reading | 7.0 | 6.5 |
| Writing | 6.5 | 6.5 |
| Speaking | 6.5 | 6.5 |
- Candidate A: 7.0 + 7.0 + 6.5 + 6.5 = 27.0 ÷ 4 = 6.75 → rounds up to 7.0. Target met.
- Candidate B: 7.0 + 6.5 + 6.5 + 6.5 = 26.5 ÷ 4 = 6.625 → rounds to 6.5. Just short.
The lesson: an average that lands on .625 rounds down, but .75 rounds up. Lifting one skill by half a band (Candidate B raising Reading to 7.0) would tip the whole result over the line. This is why your weakest skill is usually where practice pays off most.
Common beginner mistakes
- Aiming for "as high as possible" instead of a target. Find the band your university or visa needs, then aim just above it.
- Forgetting one weak skill drags the average down. A 4.5 in Writing can pull a strong profile below the line - balance matters.
- Misreading requirements. Some institutions want a minimum in each skill, not just an overall band. Always check both.
- Assuming the overall band is all that counts. A 7.0 overall with a 5.5 in Writing may still be rejected if a 6.5 minimum per skill is required.
Try it
Pick a band you'd realistically like to reach. Invent four plausible section scores that would just hit it, then add and divide them to check your maths and the rounding. Try a second set where one skill is half a band lower and see whether you still make it. This makes the scale feel real rather than abstract.
