How IELTS Band Scores Are Calculated (and How the Overall Score Is Rounded)

Fatima from Lucknow scored 6.5 in Listening, 6.5 in Reading, 5.0 in Writing and 7.0 in Speaking, and assumed her overall band would be 6.0. It was 6.5.

Each skill gets a band from 0 to 9 in half-band steps, and your overall band is the average of the four, rounded to the nearest half or whole band. An average ending in .25 rounds up to the next half band, and one ending in .75 rounds up to the next whole band.

The IELTS Band Scale and What Each Level Means

Half bands sit between these official descriptions, and CEFR levels are approximate; for example, 8.5 counts as C2 and 5.5 as B2 on the CEFR scale.

How Each Individual Skill Is Marked

Each skill gets its band in a different way:

• Listening and Reading: your band comes from the number of correct answers out of 40. See the raw score to band guide for the mark boundaries.
• Writing: marked against four equally weighted criteria: Task Achievement (Task 1) or Task Response (Task 2), Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy. Task 2 counts twice as much as Task 1; see how to describe graphs and charts for Academic Task 1.
• Speaking: marked by a certified human examiner against four equally weighted criteria: Fluency and Coherence, Lexical Resource, Grammatical Range and Accuracy, and Pronunciation. Our IELTS Speaking guide shows how the bands differ.

The Official Rounding Rule and Three Worked Examples

Because four half-band scores are averaged, the average can only end in one of eight ways (using 6.x as the example):

• 6.0 → 6.0
• 6.125 → 6.0
• 6.25 → 6.5
• 6.375 → 6.5
• 6.5 → 6.5
• 6.625 → 6.5
• 6.75 → 7.0
• 6.875 → 7.0

Three worked examples:

• Fatima: 6.5 + 6.5 + 5.0 + 7.0 = 25 ÷ 4 = 6.25 → 6.5
• Arjun: 6.5 + 6.5 + 5.5 + 6.0 = 24.5 ÷ 4 = 6.125 → 6.0
• Sneha: 7.5 + 7.0 + 6.5 + 6.5 = 27.5 ÷ 4 = 6.875 → 7.0

Arjun’s 6.125 is closer to 6.0 than to 6.5, so it rounds down. Fatima’s 6.25 sits halfway between 6.0 and 6.5, so it rounds up.

Why Per-Skill Minimums Often Matter More Than the Overall Band

A strong overall score does not protect you if one skill falls short. For instance, a requirement of “7.0 overall, no band below 6.5” is not met by an applicant with a 7.5 overall band and a 6.0 in Writing. To see how organisations set these requirements, read score requirements by country.

If one skill comes in below your target, an Enquiry on Results (re-mark) may be worth considering.

To find the cheapest half band, look at where you can gain fastest. In our experience, many Indian candidates improve quickest in Listening and Reading, where test technique helps raw scores. Writing usually needs longer.

Common Scoring Misconceptions

Quick Check

1. Calculate the overall band for scores of 7.0, 6.5, 6.0 and 6.0.
2. Calculate the overall band for scores of 8.0, 7.5, 6.5 and 7.0.

Key Takeaways

• All four skills carry equal weight in your overall score.
• Averages ending in .25 and .75 round up.
• Whole bands have official descriptions; half bands sit between them.
• A minimum for each skill can rule out an otherwise high overall band.
