Scored a 6.5 on the IELTS and not sure if that’s enough? Or maybe you haven’t taken the IELTS test (International English Language Testing System) yet and want to know what to aim for. Either way, the answer depends on where you are applying, though most competitive U.S. schools want to see at least a band score of 6.5 to 7.
Here’s what the score actually measures, what’s considered competitive, and how long it stays valid after you earn it.
The IELTS score range is 0 to 9, in half-point steps. Four separate scores make up that number: Listening, Reading, Writing, and Speaking, each scored on its own 0-to-9 scale. To get your overall score, these four scores are averaged and rounded to the nearest half band.
A 9 is the highest possible score, the IELTS max score and IELTS highest score, described as an “expert” user: someone whose English is very close to that of a highly educated native speaker. Very few test-takers achieve a 9 in every section. In practice, this means a strong IELTS listening score or IELTS reading score can raise your average even if your IELTS writing score or IELTS speaking score is lower, since the final number is simply the average of all four.
There’s no single exact number that works for everyone, but here’s a general guide by goal, using the range of TOEFL scores you’ll see across most admissions pages:
The number on a school’s admissions page is usually a minimum, not a target. Programs with a strong writing component often expect a score higher than that minimum. You may also see these referred to as TOEFL grades or TOEFL test grades, just different wording for the same scoring system.
An IELTS score is valid for two years from your test date. After two years, it is no longer accepted for new applications, so if you do not plan to apply right away, keep this timeline in mind before you schedule your test.
Here is how IELTS compares to TOEFL and Duolingo:
| Test | Score Range | Max Score | Typical "Good" Score | Validity |
|---|---|---|---|---|
| IELTS | 0–9 (band score) | 9.0 | 6.5–7+ | 2 years |
| TOEFL iBT | 1–6 | 6 | 4–5 | 2 years |
| Duolingo English Test | 10–160 | 160 | 105–125+ | 2 years |
