TOEFL vs Duolingo English Test: Which Should You Take?
Last updated: August 15, 2026
Short answer: take Duolingo English Test (DET) if you want the cheapest, fastest, fully-at-home option and your target university explicitly accepts it. Take TOEFL iBT if you’re applying to an elite or technical university — Ivy League institutions and strict European technical universities typically still require traditional TOEFL over DET — or if you need a test with the widest possible institutional recognition.
TOEFL vs Duolingo: Side-by-Side
| Feature | TOEFL iBT | Duolingo English Test |
|---|---|---|
| Format | At-home edition or in-person at an official ETS test centre | Fully online, taken from home via webcam, AI-monitored |
| Duration | About 90 minutes (2026 format) | About 1 hour |
| Scoring scale | 0–120 traditional, plus a new 1–6 band scale (0.5 increments) introduced in 2026 | 10–160 points |
| Results turnaround | 4–8 days typically | Within 48 hours |
| University acceptance | Very broad, including most elite/Ivy League and technical universities | 6,600+ universities, but often not elite Ivy League or strict European technical institutions |
Example conversion: a DET score of 110 is roughly equivalent to 76–81 on the traditional TOEFL 0–120 scale, or about a 4.0 on TOEFL’s new 2026 band scale (source: Shiksha, Duolingo to TOEFL score conversion). Treat this as an estimate — always confirm with your specific university’s published conversion table.
The Real Dividing Line: Institution Tier
Unlike the IELTS-vs-DET comparison, where the dividing line is mostly about visas, the TOEFL-vs-DET decision is mostly about which universities you’re targeting. DET’s acceptance has grown to over 6,600 institutions, but the most selective, research-intensive, and technical universities — particularly Ivy League schools in the US and rigorous technical universities across Europe — still lean toward requiring traditional TOEFL (or IELTS) over DET. If your list includes any of these, don’t take the risk on DET alone; check each university’s admissions page individually.
Decision Framework
- Are any of my target universities highly selective, Ivy League, or a strict technical institution? If yes, default to TOEFL unless their page explicitly names DET as accepted.
- Do I need the fastest possible turnaround and lowest cost? DET wins on both.
- Will this score ever be used for anything beyond straightforward university admission? TOEFL’s broader recognition is the safer long-term bet.
- Am I more comfortable with a shorter adaptive test at home, or a structured, in-person/proctored academic exam?

Frequently Asked Questions
Do Ivy League universities accept Duolingo English Test?
Some do, on a case-by-case basis, but many still list traditional TOEFL or IELTS as the preferred or required test. Always check each specific university’s admissions requirements rather than assuming.
Is Duolingo English Test accepted at the same rate as TOEFL?
No — DET is accepted by roughly 6,600 institutions globally, while TOEFL’s acceptance is broader and includes nearly all major universities, including the most selective ones that don’t yet list DET.
How much cheaper is Duolingo than TOEFL?
DET is a highly cost-effective option — roughly a fraction of TOEFL’s standard institutional exam fee — making it attractive for students on a tight budget, provided their target university accepts it.
