IELTS to TOEFL to Duolingo Score Converter
Compare IELTS, TOEFL iBT (new 1–6 and old 0–120 scales) and Duolingo English Test scores using the official concordance tables.
0–9 in steps of 0.5
Equivalents are a guide. Universities set their own minimums for each test, and some ask for minimum section scores too. Sources: ETS (2026-04), Duolingo (2026-03).

How this tool works
- The tool reads equivalents from three official tables: ETS's 2026 banded TOEFL iBT scale (IELTS, CEFR and old 0–120 equivalents), and Duolingo's 2026 scoring guide (DET against IELTS, old TOEFL and CEFR).
- A TOEFL band of 1–6 corresponds to a minimum old-scale total, for example band 4.0 is 72 and band 5.0 is 95. The old 0–120 total is shown as a range for the band.
- IELTS overall scores from 4.0 to 9.0 map to a TOEFL band using ETS's table, which rounds up to avoid overstating ability. IELTS scores below 4 are shown only against a Duolingo range of 10–55.
- Results marked as derived chain two tables. Duolingo still compares against the old 0–120 TOEFL scale, so a Duolingo-to-band result combines Duolingo's table with ETS's.
- Universities set their own minimums and often require section scores, so treat the output as a guide, not an acceptance rule.
