How the Overall Band Score Is Calculated

Your overall score is the arithmetic mean of the four section scores, rounded to the nearest whole or half band. The rounding rule published by IELTS is:

  • If the average ends in .25, it rounds up to the next half band.
  • If the average ends in .75, it rounds up to the next whole band.

Example: L 7.0 + R 6.5 + W 6.0 + S 7.0 = 26.5 ÷ 4 = 6.625 → rounds to 6.5

Example: L 7.0 + R 7.0 + W 6.5 + S 7.0 = 27.5 ÷ 4 = 6.875 → rounds to 7.0

Listening Score Conversion

Listening has 40 questions. Each correct answer = 1 raw mark. The raw mark maps to a band score:

Raw ScoreBandRaw ScoreBand
39–409.023–256.0
37–388.520–225.5
35–368.016–195.0
33–347.513–154.5
30–327.010–124.0
27–296.56–93.5

Note: These are approximate indicative scores published by the British Council. Actual conversion may vary slightly between test versions.

Reading Score Conversion

Reading also has 40 questions, but the raw-to-band conversion differs between Academic and General Training:

BandAcademic Raw ScoreGT Raw Score
9.039–4040
8.035–3638–39
7.030–3234–35
6.023–2527–29
5.016–1919–22

General Training Reading requires more correct answers per band because the texts are less academically complex.

Writing and Speaking Scoring

Writing and Speaking are assessed by certified IELTS examiners against published band descriptors. Each section is scored on four criteria, each weighted equally at 25%:
