IELTS Band Formula

You will be given a mark between 0 and 9 for each of the 4 Sub-tests (there are no half marks in the Writing and Speaking Sub-tests).

Your Overall Band Score is an average of the 4 Sub-test Band Scores, with fractional scores rounding up or down to the nearest x.0 or x.5 score (with x.25 and x.75 rounding up.)

Therefore, if you score

6.5 in the Listening Sub-test
5.0 in the Reading Sub-test
7.0 in the Writing Sub-test
6.0 in the Speaking Sub-test
__
Your total score is
24.5

By averaging the scores (dividing the total score 24.5 by 4) in the example above, you would achieve an overall Band Score of 6.0 (which is 6.125 rounded down).
