Key Takeaways
- The right test is the one your target program accepts before your deadline with the lowest execution risk, not simply the easier or cheaper exam.
- TOEFL iBT changed in 2026: ETS now reports section and overall scores on a 1-6 scale, with a comparable 0-120 score during a two-year transition, so older prep and conversion charts need a careful check.
- Choose DET for a faster, lower-cost, at-home route when every program accepts it; choose TOEFL for the broadest recognition or when any school, scholarship, or visa requires it.
- Verify acceptance on the exact program page for your degree level and intake, not the university homepage, and confirm scholarship, visa, and assistantship rules separately.
- Plan for cost, score timing, and retake windows: ETS posts TOEFL scores 3 days after the test, DET allows three purchases per 30-day period, and TOEFL retakes cannot be within 3 days.
Choosing between the Duolingo English Test (DET) and TOEFL iBT is not only a question of difficulty. The real issue is whether your target programs accept the score, whether the format fits your strengths, and whether your deadline can survive score reporting, retakes, and possible remote-testing problems.
The comparison changed in 2026 because TOEFL iBT moved into a new scoring and test-content model. Old DET vs TOEFL advice that compares DET against the pre-2026 TOEFL section table is no longer enough. You need a current decision framework.
Quick Answer
Choose DET when every target program accepts it, cost matters, you need a faster route, and you are comfortable with adaptive at-home testing. Choose TOEFL when any target program requires it, when visa or professional rules are unclear, or when you prefer a longer but more structured academic-English exam.
If one school accepts DET and another only lists TOEFL, the answer is simple: take TOEFL or ask the second school for written confirmation before paying for DET. The cheapest test is still expensive if it cannot be used for your application.
What Changed in 2026
The largest change is on the TOEFL side. ETS now describes TOEFL iBT as an adaptive test with Reading, Listening, Writing, and Speaking tasks, approximate base times, and a new score report. The official TOEFL content page says test takers receive section and overall scores on a 1-6 scale, with a comparable 0-120 score during a two-year transition after January 2026. Our TOEFL iBT exam page tracks the current format and what it means for planning.
DET has not had the same kind of 2026 format reset. Duolingo says the test reports a 10-160 score and measures reading, writing, listening, and speaking through overall and integrated subscores. Duolingo also reports that over 6,000 programs and institutions accept DET globally. See the Duolingo English Test exam page for a quick format and scoring snapshot.
The practical consequence: score-conversion charts are weaker than official admissions pages. A school may update TOEFL language before it updates DET language, or accept DET for undergraduate admission but not a graduate program, scholarship, licensure route, or visa file.
Quick Comparison: Duolingo vs TOEFL
| Factor | Duolingo English Test | TOEFL iBT |
|---|---|---|
| Core use | Fast at-home English proof for accepting programs | Broad academic-English proof with long institutional history |
| Test time | Usually under one hour | About 90 minutes of base test content; ETS says to allow about two hours overall |
| Score scale | 10-160 | 1-6 scale, with comparable 0-120 score during transition |
| Acceptance | Duolingo reports over 6,000 accepting programs/institutions | ETS says TOEFL is accepted by more than 13,000 institutions in over 160 countries |
| Cost | Usually much lower; verify current checkout price in your DET account | Registration fee varies by country; ETS lists separate service fees |
| Score timing | Generally fast; plan for certification review | ETS says scores are available in your ETS account 3 days after test date |
| Retake planning | Duolingo allows three test purchases in any 30-day period | TOEFL retakes cannot be scheduled within 3 days of another TOEFL iBT test |
Duolingo English Test: Strengths and Risks
Where DET Is Strong
DET is strong when speed, access, and cost matter. You can test at home, avoid test-center travel, send scores widely, and move quickly when a university accepts DET for your program. The adaptive format can also feel less exhausting than a longer fixed-form test.
Where DET Can Backfire
The risk is not only the score. DET is remote-proctored, so behavior, environment, ID, camera, microphone, browser, and internet stability all matter. Duolingo's test credit policy says one credit can produce one certified result, but rule violations, possible misconduct, or repeated issues can cause the credit to expire or lead to suspension.
DET also backfires when students assume university-level acceptance means program-level acceptance. Admissions pages often separate undergraduate, graduate, MBA, nursing, teaching, visa, and conditional-admission rules. Read the exact program page, not only the university's central English-test page.
TOEFL iBT: Strengths and Risks
Where TOEFL Is Strong
TOEFL remains the safer broad-application choice when your school list is uncertain. ETS says TOEFL scores are accepted by more than 13,000 institutions in over 160 countries, and many universities already have mature TOEFL minimums in their admissions systems.
Where TOEFL Can Backfire
TOEFL can be the wrong choice when cost, timing, or format is the limiting factor. ETS says registration fees vary by location and lists service fees such as US$29 for each additional score report. If your application list is large and every school accepts DET, TOEFL may be unnecessary.
The 2026 update also means older TOEFL prep material needs a careful check. If a course, book, or template only explains the old section timing and old 0-120-only score report, treat it as incomplete for current TOEFL planning.
Acceptance Is a Policy Question, Not a Popularity Contest
Do not choose based on global acceptance numbers alone. TOEFL's acceptance footprint is broader, but DET may be accepted by every program on your list. DET's lower cost is attractive, but it does not help if one scholarship office, visa process, or graduate department requires TOEFL or IELTS.
How to Verify Acceptance
- Check the exact program page, not only the university homepage.
- Confirm whether the rule applies to your degree level and intake year.
- Look for minimum overall scores and section/subscore minimums.
- Check whether the same rule applies to scholarships, visas, and assistantships.
- Save screenshots or written confirmations before booking if the page is unclear.
Use the TOEFL score requirements guide and TOEFL 2026 format guide if you are leaning toward TOEFL. Use the IELTS vs TOEFL comparison or PTE Academic guide if your program accepts several English tests.
Cost, Score Timing, and Retake Rules
DET is usually the lower-cost route, and current public DET checkout pricing is around $70 before bundles or add-ons. Because Duolingo's live checkout can change by product option, verify the price in your account before relying on a budget. TOEFL pricing varies by country, and ETS publishes country-specific registration fees plus service fees.
For timing, ETS says TOEFL scores are available 3 days after the test date. Duolingo is typically fast, but certification review still matters. A fast test is only useful if the score is certified and accepted before the application deadline.
Retake planning matters for both tests. Duolingo says you must wait for results before taking a new test and may purchase three tests in any 30-day period. TOEFL's bulletin states that you cannot take TOEFL more than once in a 3-day period. If you have a deadline, build a calendar with score release plus at least one retake window.
Which Should You Choose?
Choose DET If
- Every target program accepts DET for your intake and degree level.
- You need a lower-cost option and broad score sending.
- You are comfortable with remote proctoring and a highly adaptive format.
- Your deadline is close and a certified DET score can arrive in time.
- You perform better in short integrated tasks than long academic passages.
Choose TOEFL If
- Any target program, scholarship, visa, or professional process requires TOEFL.
- You want the broadest institutional recognition.
- You prefer a predictable academic-English structure and official prep ecosystem.
- You need a test-center option instead of at-home remote proctoring.
- Your older TOEFL preparation is still close enough to the updated format after review.
Common Mistakes That Lead to the Wrong Choice
- Using outdated TOEFL format advice: the 2026 TOEFL scoring update changes how you should read score requirements.
- Trusting conversion charts too much: schools set their own equivalencies, and some do not publish clean DET-to-TOEFL conversions.
- Checking only central admissions pages: graduate departments can set stricter rules than university-wide pages.
- Ignoring score delivery: a score posted in your account is not always the same as a score received and processed by the school.
- Underestimating remote proctoring: at-home convenience becomes a liability if your room, ID, camera, microphone, or internet setup is weak.
Need Help with Your English Exam?
Exam Assist supports candidates who need a usable English-test result under deadline pressure. The starting point is not a generic promise. It is the target test, target score, program policy, deadline, previous score if any, and the reason your current plan is risky.
For DET-specific support, review the Duolingo English Test assistance page. For TOEFL, use the TOEFL assistance page and compare it with the TOEFL speaking tips and IELTS first-time strategy if you are still weighing English-test options.
The pay-after-pass model is most relevant when the acceptance policy is already confirmed and the remaining problem is execution. A second pay-after-pass mention belongs here because the financial promise should stay tied to a real result, not to vague exam confidence.
Final Takeaway
DET is usually the faster, cheaper, more accessible route when your schools accept it. TOEFL is usually the safer universal route when acceptance rules are unclear or broad recognition matters. The correct answer is the test that satisfies your target program before your deadline with the lowest execution risk.
