Direct answer

IELTS reports bands in 0.5 steps (6.0, 6.5, 7.0), and honest AI tools show a range when criterion scores disagree, not a false-precision single number. After one mock, treat ±0.5 as normal noise until three timed attempts agree. Your realistic window is bounded by your weakest criterion band, not your best paragraph. Use ranges to decide whether to book, not to chase a lucky headline score.

How IELTS bands are reported

0.5 steps Scores like 6.0, 6.5, 7.0, no 6.3

Per skill Listening, Reading, Writing, Speaking reported separately

Overall Mean of four skills, rounded again to 0.5

What AI "ranges" usually mean

Label	Meaning
6.5–7.0 range	Model uncertainty or criterion spread, not a promise
Single Band 7	One snapshot; verify on fresh prompts
Confidence %	Model certainty, not examiner odds

Using ranges without overbooking

Log three timed mocks per skill. If the lowest band in the range is still below target, you are not exam-ready. See comparing multiple AI scores.

Key takeaways

IELTS uses 0.5 increments. AI should too.
Ranges express uncertainty; they are not official TRF spreads.
Weakest skill sets your study plan, not your best mock.
Three agreeing mocks beat one lucky Band 7.

FAQ

Treat ±0.5 from your mock as normal noise until three timed attempts agree. Wider spreads mean unstable scoring or mixed prompt types.

Each skill averages sub-scores (e.g. four Writing criteria) then rounds to the nearest 0.5 using standard rounding rules.

Only when the bottom of a calibrated range meets your target on the weakest skill, not when a single optimistic mock hits it.
