TOEFL iBT
ETS's scale introduced on 21 January 2026 uses half bands from 1 to 6. Its CEFR table applies to overall and all skill scores. Legacy 0–120 totals and 0–30 skills are grouped from ETS's currently published comparison bins, with no interpolation.

Frequently asked questions
Which TOEFL scale is supported?
The current band scale for overall or any skill, plus legacy total and individual reading, listening, speaking and writing scores. Labels distinguish them. The legacy alignment uses ETS's current comparison, not the older CEFR table.
Are the other test ranges equivalent scores?
They share a broad CEFR alignment. Concordances are approximate, individual results vary, and institutions set their own requirements. A skill score does not establish overall proficiency.
Why are some levels missing or combined?
IELTS does not report separate A1/A2 ranges in the cited table. Duolingo's cited guide combines A1–A2. No boundaries have been invented.
Does every Cambridge exam cover the whole scale?
No. The displayed ranges combine several qualifications; each exam reports results over a narrower range.
