What is the difference between Duolingo and IELTS exams?
IELTS costs $150 to $325 USD, runs about 2 hours 45 minutes, and is accepted by over 12,000 institutions across 140-plus countries. Duolingo has a fixed $70 USD fee, takes roughly an hour, and returns results within 48 hours, making it the faster, cheaper choice for many applicants today.
IELTS and the Duolingo English Test both prove your English ability, but they work very differently when it comes to cost, timing and format. If you want a fast, affordable exam you can take from your room, Duolingo usually suits you better; if your target university or visa office specifically demands a traditional exam, you will need to sit IELTS instead.

Which Test Should You Choose
- Pick Duolingo if you are on a tight budget, need results fast, and your target school officially accepts it.
- Pick IELTS if your university or visa office specifically mandates it, or you prefer a live speaking interview with a human examiner.
- Always confirm acceptance on your shortlisted university's admissions page before you register and pay for either test.
My Advice
Before you spend money on either exam, pull up the official admissions page for every university on your shortlist and note which test each one accepts, since policies differ even within the same country. If two or more of your target schools accept Duolingo, book that test first to save time and money, then add IELTS only if a specific program requires it.
More expert answers
Duolingo English Test (DET) and IELTS both assess English proficiency, but they differ in format, length, and acceptance.
- DET: Taken online from anywhere, lasts about 1 hour, and combines reading, writing, listening, and speaking in a single adaptive test. Scored out of 160. More affordable and flexible, but not as widely accepted for university admissions or immigration as IELTS.
- IELTS: Conducted at test centers (paper or computer), lasts about 2 hours 45 minutes, and has separate modules for Listening, Reading, Writing, and Speaking. Scored on a 0 - 9 band scale. Accepted by most universities and immigration authorities worldwide.
Choose IELTS if you need broader acceptance, especially for study or immigration. For more details on which test suits your plans, connect with your LeapScholar counsellor.
