How IELTS Scoring Works: Band Scale Explained

IELTS gives you five numbers. One band for Listening, one for Reading, one for Writing, one for Speaking, and an Overall Band Score. All five use the same 0 to 9 scale and are reported in whole and half bands.

No skill outweighs another. Your Overall Band Score is the average of the four section bands, rounded to the nearest whole or half band. This guide covers the scale and its labels, how raw marks in Listening and Reading turn into bands, the four criteria behind Writing and Speaking, the rounding rule, and where to check the band your goal requires.

The 0 to 9 Band Scale

Each band carries an official label for the level of English. The same labels apply to your four section bands and to your Overall Band Score.

IELTS publishes the full scale with these labels. Band 0 records an absence of answers rather than a weak performance, so it applies when a candidate did not attempt the test.

Whole Bands and Half Bands

Bands move in steps of 0.5. A 6.0 exists and a 6.5 exists. A 6.3 does not.

Half bands appear in every section score and in the overall score. Small gains inside a section sometimes show on your Test Report Form and sometimes disappear into the rounding, which is why the overall arithmetic is worth learning before you set targets.

How Listening Is Scored

Listening has 40 questions. Each correct answer earns one mark, and your raw score out of 40 converts into a band. One conversion table covers both Academic and General Training.

Approximate marks needed for the middle and upper bands:

IELTS describes these thresholds as approximate. Read them as a guide for practice, not as a fixed pass mark.

The steps narrow as you climb. Band 6 to Band 7 is about seven more correct answers, while Band 7 to Band 8 is about five. Every mark near the top of the table costs more work than the one before it.

How Reading Is Scored

Reading also runs 40 questions worth one mark each. Academic and General Training use different conversion tables, so the same raw score produces different bands depending on which version you sat.

Approximate marks needed on Academic Reading:

IELTS publishes these Academic Reading thresholds as approximate, in the same way as the Listening figures. Read them as practice guidance, not as a fixed pass mark.

Use the table matching your test type before you judge a practice result. A greater number of correct answers is normally needed on General Training Reading to reach a given band, so an Academic threshold read against a General Training paper sets your target too low.

Why the Marks Needed Move Between Test Versions

The precise number of marks needed for each band varies slightly from test version to test version. Grading is adjusted per paper instead of running off one permanent table.

Set your practice targets as a small range rather than a single number. A raw 30 in Listening sits around Band 7 on most versions, and treating it as an exact boundary invites a surprise on test day.

How Writing Is Scored

Writing is marked against four criteria. The four carry equal weight, so each one accounts for a quarter of your Writing band.

• Task Achievement in Task 1, and Task Response in Task 2
• Coherence and Cohesion
• Lexical Resource
• Grammatical Range and Accuracy

Equal weighting has a direct consequence. One weak criterion drags the section band down no matter how strong the other three are, so a well argued essay with unstable grammar still loses a quarter of the marking.

Read the official band descriptor wording for each criterion on the IELTS site before you self-mark. The published phrasing is what examiners apply, and marking yourself against a vague memory of it produces inflated practice bands.

For the essay structure behind Task Response, read our IELTS Writing Task 2 guide.

How Speaking Is Scored

Speaking uses its own set of four criteria, also equally weighted at a quarter each.

• Fluency and Coherence
• Lexical Resource
• Grammatical Range and Accuracy
• Pronunciation

Two criteria repeat across both productive skills, and two are unique to one of them.

Vocabulary and grammar work you do for one skill pays into the other, since Lexical Resource and Grammatical Range and Accuracy are marked in both. Pronunciation practice pays into Speaking alone. For the interview format and the three parts, read our IELTS Speaking section guide.

How Your Overall Band Score Is Calculated

The Overall Band Score is the average of the four section bands, rounded to the nearest whole or half band. Nothing is weighted, and no section is dropped.

The whole calculation runs in three steps:

1. Add your Listening, Reading, Writing and Speaking bands
2. Divide the total by four
3. Round the result to the nearest whole or half band

An average ending in .25 rounds up to the next half band, and an average ending in .75 rounds up to the next whole band. Both midpoints go up, never down. Any other average moves to whichever half band is closer, so 6.125 becomes 6.0 and 6.375 becomes 6.5.

Worked Examples

Four section bands, one average, one printed result:

Row two and row four show the rule people misread. Both averages land between half bands and below the next midpoint, so each moves to the nearer half band, and only the exact .25 and .75 midpoints round up automatically.

Our IELTS band calculator runs the same arithmetic. Enter four section bands and read the overall result without rounding by hand.

What the Rounding Rule Means for Your Study

Half a band gained in one section moves your average by 0.125, an eighth of a band. On its own, the gain often vanishes in the rounding.

Two half-band gains move the average by 0.25 and usually cross a line. Planning improvement across two sections beats grinding a single one, especially when one section is already near your ceiling.

Your lowest section is the cheapest place to find those gains, since it has the most room left and its raw-score thresholds sit lower down the conversion table.

Where to Check the Band You Need

The band you need comes from the organisation receiving your score, not from IELTS. Universities, employers and immigration authorities each publish their own requirement.

Before you set a target, confirm four things:

• The published requirement for your exact program or visa route
• Whether a minimum for individual sections applies alongside the overall band
• Which test type is accepted, Academic or General Training
• How recent the score has to be on the date you apply

For a sense of what the numbers mean across applicants, read our guide to what counts as a good IELTS score and our IELTS percentiles guide. For the format behind each section band, read our IELTS exam guide.

How to Score Your Own Practice

Score practice the same way IELTS does, then average it. Guessing an overall band from a general feeling about your English produces numbers with no relationship to your Test Report Form.

1. Mark Listening out of 40 and convert with the official table
2. Mark Reading out of 40 using the table for your test type
3. Self-mark Writing against its four criteria and take the band each one supports
4. Record a Speaking answer and mark it against its four criteria
5. Average the four bands and round with the tie-up rule

Repeat the same routine every time, because a consistent method makes the movement between attempts meaningful even when your self-marking runs a little generous.

Our IELTS page carries full-length mocks under real timing and question-type drills for the skills costing you marks. Everything is free and needs no signup. Sit a full mock on our IELTS practice page, convert your Listening and Reading raw scores, then drill your weakest skill until the section band moves.
