IELTS to TOEFL to Duolingo Score Converter
The WitPrep IELTS ↔ TOEFL ↔ Duolingo converter is a free instant lookup tool that maps any IELTS band (0–9), TOEFL iBT score (0–120), or Duolingo English Test score (10–160) to the equivalent score on the other two tests. It uses the official ETS concordance, the published British Council / IDP IELTS comparison, and Duolingo's research-backed alignment so you can compare your English-proficiency score to any university's requirement in seconds — without signing up.
Verdict at a Glance
Use this converter when you already have one English-test score and need to know what it's worth on the other accepted tests at your target universities. The conversions are reliable for admissions planning (within ±1 IELTS half-band) but not a substitute for an official score report — universities accept only scores issued directly by ETS, the British Council/IDP, or Duolingo.

Frequently Asked Questions
How do I convert my IELTS score to TOEFL?
Enter your IELTS band in the converter and it returns the equivalent TOEFL iBT score. For example, IELTS 7.0 is approximately equivalent to TOEFL iBT 94–101. The conversion is based on the official ETS-published concordance between IELTS and TOEFL.
What TOEFL score is equivalent to IELTS 6.5?
An IELTS band score of 6.5 is approximately equivalent to a TOEFL iBT score of 79–93. Many US graduate programs use TOEFL 79 / IELTS 6.5 as the published minimum. Always check your target school's specific requirement.
Can I convert Duolingo English Test scores to IELTS or TOEFL?
Yes. A Duolingo English Test score of 120 is roughly equivalent to IELTS 7.0 or TOEFL iBT 100. The full Duolingo-to-IELTS chart is published by Duolingo and integrated into this converter.
Do universities accept IELTS instead of TOEFL?
Most universities worldwide accept both. Over 11,000 institutions across 150+ countries accept IELTS, and over 11,500 institutions accept TOEFL. Check your target university's published English-test list before booking a test.
Is the WitPrep converter accurate enough for university applications?
The conversions match the official ETS, British Council, and Duolingo concordance tables and are accurate for shortlisting and retake planning. Universities still require an official score report sent directly by the testing organization — this tool is for planning, not for submission.
Which English test is cheapest?
Duolingo English Test is usually the cheapest (about $59 USD). TOEFL iBT is $185–$245 depending on country. IELTS Academic is $245–$255. Acceptance varies — check that your target universities accept Duolingo before relying on it for cost savings.
How long are IELTS, TOEFL, and Duolingo scores valid?
IELTS and TOEFL iBT scores are valid for 2 years from the test date. Duolingo English Test scores are also valid for 2 years. After expiry you'll need to retake the test for new admissions or visa applications.
Should I send my converted score to universities?
No. Universities accept only official score reports sent directly by ETS, the British Council/IDP, or Duolingo. The converter helps you plan and shortlist — once you choose a target university, send the score from the test you actually sat.
