Onterra TutorTOEFL iBT to IELTS: what your TOEFL iBT band is worth
You hold a TOEFL iBT result and want to know where it lands on IELTS. The table below is keyed by your TOEFL iBT band, with the IELTS range the boards align with it beside it.

Try a different band. The answer names the CEFR level and the range on every other test, a published alignment and so a range, not a promise.
Reading your TOEFL iBT result
A TOEFL iBT result now reports on a 1 to 6 band scale in half bands, aligned to the CEFR. If an older score report shows the 0 to 120 total, that figure is only a comparison score during the transition that runs to January 2028, so work from the band score here.
TOEFL iBT bands and where they land on IELTS
Rows are keyed by the TOEFL iBT band you hold. The IELTS column is the range the boards align with the same CEFR level.
| TOEFL iBT | CEFR | IELTS |
|---|---|---|
| 6.0 | C2 Proficient | 8.5 to 9.0 |
| 5.0 to 5.5 | C1 Advanced | 7.0 to 8.0 |
| 4.0 to 4.5 | B2 Upper intermediate | 5.5 to 6.5 |
| 3.0 to 3.5 | B1 Intermediate | 4.0 to 5.0 |
| 2.0 to 2.5 | A2 Elementary | 3.0 to 3.5 |
I have TOEFL iBT 4.5: what is that on IELTS?
Say your TOEFL iBT result is 4.5. On the boards' published alignments that band sits at CEFR B2 (upper intermediate), and the IELTS range placed at the same level is 5.5 to 6.5. So an IELTS result inside 5.5 to 6.5 says roughly the same thing about your English as your 4.5 does.
TOEFL iBT 4.0 is the lowest band the boards place at B2. One step lower, 3.5, falls to B1, so a result just under a level line can read a whole level down on IELTS. If you are a step or two under, it is worth knowing before you book a resit.
I need IELTS 7.0: what do I need on TOEFL iBT?
Now the other way round: suppose the institution asks for IELTS 7.0. That figure sits at CEFR C1, and the TOEFL iBT bands placed at that level run 5.0 to 5.5. Aim for the bottom of 5.0 to 5.5 as the lowest result that lines up, and for something above it if you want room to spare.
IELTS asks for an overall band and often a minimum in each skill. The test includes a face-to-face speaking interview, so the conversion shows the level to aim at but not whether that format suits you.
TOEFL iBT to IELTS: questions people ask
I scored 4.5 on TOEFL iBT. What is that on IELTS?
TOEFL iBT 4.5 sits at CEFR B2, and the IELTS range aligned with B2 is 5.5 to 6.5. It is a range because both boards publish their alignment by level, not by single score.
Is the TOEFL iBT to IELTS conversion official?
No board publishes a table between TOEFL iBT and IELTS. This page goes through the CEFR level each board assigns to its own scores, so every figure here is an approximate range.
My TOEFL report shows two different scales. Which do I convert?
Convert the 1 to 6 band score. The 0 to 120 total is kept as a comparison score during a transition that runs to January 2028, and it is the band score that carries the CEFR alignment.
Will an institution that asks for IELTS take a converted score?
Only if it says so. A conversion helps you choose which test to sit, but the institution decides which tests it accepts and at what score, so read its list of accepted tests before relying on any table.
