Deciding which English proficiency test is better for university admission in the US often comes down to the specific requirements of your target schools. While TOEFL is historically the most widely accepted test by US institutions, IELTS is also almost universally recognized. The Duolingo English Test is a convenient and affordable modern alternative that is gaining popularity, but you must verify its acceptance with each university individually.
For decades, international students have viewed English language tests as a critical gateway to higher education in the United States. With three major players in the field—IELTS, TOEFL, and the Duolingo English Test (DET)—making the right choice can feel overwhelming. This guide breaks down the key factors to help you determine which English proficiency test is better for university admission in the US for your specific journey.

Which English Proficiency Test is More Accepted by US Universities?
The most critical factor is whether your dream university will accept your test score. Acceptance policies can vary significantly, especially for newer tests like Duolingo.
TOEFL: The Traditional Gold Standard
For US university admissions, TOEFL has long been the dominant test. It is accepted by over 11,000 universities in more than 190 countries and is the preferred test for 9 out of 10 universities in the United States. If you want a single test that guarantees the widest possible acceptance across American institutions, TOEFL iBT is often the safest bet.
IELTS: The Global Competitor
While TOEFL has a slight edge in the US, IELTS Academic is a close second and is accepted by over 3,400 institutions in the USA, including all Ivy League universities. Its global recognition is immense. The primary difference is often institutional preference rather than a lack of acceptance. Always check the admissions page of your target university, but it's rare to find a US school that accepts TOEFL but not IELTS.
Duolingo: The Modern Challenger
The Duolingo English Test has seen a massive surge in acceptance, particularly since 2020. Thousands of US universities now accept it, including prestigious names like Yale, Columbia, and Duke. However, its acceptance is not yet universal. Some universities may only accept it as a supplement, while others, especially highly competitive graduate programs, may still require TOEFL or IELTS. The rule here is simple: never assume. Always verify on the university's official admissions website.
How Should You Choose the Right Test for You?
Beyond acceptance, your personal preferences and strengths should guide your choice. Consider these factors:
- Test Environment: Do you perform better under pressure in a formal test center (TOEFL/IELTS), or do you prefer the comfort of your own home (Duolingo)?
- Speaking Section Style: Would you rather speak into a microphone in response to a computer prompt (TOEFL) or have a conversation with a human examiner (IELTS)?
- Budget and Time: Duolingo is significantly cheaper and faster, with results available in just two days. TOEFL and IELTS are more expensive and take 1-2 weeks for results.
- Content Style: TOEFL is 100% focused on academic English in an American context. IELTS incorporates various global accents and task types.
Ultimately, deciding which English proficiency test is better for university admission in the US is a personal calculation based on three pillars: university acceptance, your test-taking style, and practical constraints like budget and location. Start by building your list of target universities, check their requirements, and then choose the test that sets you up for success.
Frequently Asked Questions About English Tests for US Universities
Is the Duolingo test score accepted for Ivy League schools? Yes, many Ivy League universities like Yale, Columbia, Dartmouth, and Cornell accept the Duolingo English Test for undergraduate admissions. However, policies can change, and specific graduate programs within those universities may have different requirements, so it's crucial to check the exact program's admissions page.
Do I need to take an English proficiency test if I studied in an English-medium school? It depends on the university's policy. Many US universities will waive the English proficiency test requirement if you completed your secondary or post-secondary education where the primary language of instruction was English. You typically need to provide official documentation to request a waiver.
How long are TOEFL, IELTS, and Duolingo scores valid? For all three tests—TOEFL, IELTS, and the Duolingo English Test—scores are considered valid for two years from the test date. Universities will not accept scores that are older than this two-year window.
Is TOEFL harder than IELTS for non-native speakers? Neither test is objectively 'harder'; they are just different. Some students find the integrated tasks and computer-based speaking of TOEFL more challenging, while others struggle with the variety of accents and the face-to-face speaking interview in IELTS. Your personal skills and learning style will determine which one feels more difficult for you.
