Duolingo English Proficiency Test: Requirements, Format & Duration (2026)

Passport and laptop on desk - Duolingo English Test requirements

Before you can take the Duolingo English Test, you need to meet a few requirements. The good news: they're simpler than IELTS or TOEFL. No test centers. No appointments weeks in advance. No dress code.

But there are still rules. Break them and your test gets invalidated — even after you've finished.

This guide covers every requirement: eligibility, ID, equipment, environment, and score thresholds for universities. Once you know you qualify, check out our complete DET preparation guide to start studying.

Eligibility Requirements

The DET has almost no eligibility restrictions:

  • Age: No minimum age. However, test takers under 13 need parental consent.
  • Nationality: Anyone can take it, from any country.
  • Education: No prior qualifications required.
  • English level: No minimum. You can take it at any proficiency level.

Unlike some tests that require you to be a "non-native speaker," the DET doesn't check your background. If you need a score, you can take the test.

ID Requirements

You need a valid, government-issued ID. The DET accepts:

  • Passport (preferred by most universities)
  • National ID card
  • Driver's license
  • Resident permit

Your ID must show:

  • Your full legal name
  • Your photo
  • Your date of birth
  • An expiration date (must not be expired)

Important: The name on your ID must match the name you use when registering. If they don't match exactly, your results may be invalidated or rejected by institutions.

You'll photograph your ID during the test setup process. Make sure it's clearly readable — no glare, no blur, no fingers covering text.

System and Technical Requirements

The DET runs in a browser on your computer. Here's what you need:

Computer

  • Operating system: Windows 10+, macOS 10.15+, or ChromeOS
  • Browser: Latest version of Chrome, Edge, Opera, or Safari (Firefox not supported)
  • RAM: At least 4GB

Tablets and phones don't work. You need a laptop or desktop.

Camera and Microphone

  • Front-facing camera (built-in or external)
  • Working microphone
  • Speakers or headphones (earbuds allowed, but no earphones with microphones that cover your ears)

The camera records you throughout the test. The microphone captures your speaking responses. Both get reviewed by human proctors after you finish.

Internet Connection

  • Minimum: 2 Mbps download speed
  • Recommended: 10+ Mbps for smooth performance
  • Stable connection (avoid public WiFi)

If your connection drops during the test, you may be able to resume — but interruptions raise red flags for proctors.

Pro tip: Run Duolingo's official system check before test day. It tests your camera, microphone, and internet. Do this at least 24 hours before your scheduled test. See our complete setup checklist →

Environment Requirements

Where you take the test matters as much as your equipment.

Room Setup

  • Quiet space: No background noise, no other people talking
  • Alone: No one else in the room during the test
  • Well-lit: Your face must be clearly visible on camera
  • Clean background: No notes, no books, no second screens visible

What You Cannot Do

  • Look away from the screen (except during breaks)
  • Leave the camera frame
  • Use notes, books, or other materials
  • Wear headphones that cover your ears completely
  • Have anyone else in the room
  • Use a phone or second device

Test invalidation: If proctors see suspicious behavior in your recording — looking off-screen repeatedly, another person visible, background voices — your test will be invalidated. You won't get a refund, and you'll need to retake it.

Score Requirements for Universities

Different institutions require different minimum scores. Here are typical thresholds:

Institution Type Typical Minimum Score
Community colleges 85–95
State universities (undergraduate) 100–110
Competitive universities 115–125
Top-tier universities (Ivy League, etc.) 125–135+
Graduate programs 110–130 (varies widely)

Always check your target institution's specific requirements. Scores are valid for 2 years from your test date.

For a detailed breakdown of what scores mean and how they compare to IELTS/TOEFL, see our DET passing score guide.

Registration Requirements

To register for the DET:

  1. Create a free account at englishtest.duolingo.com
  2. Purchase a test ($65 USD as of 2025)
  3. Complete the test within 21 days of purchase

You can take the test immediately after purchasing — no scheduling required. Results arrive within 48 hours.

Retake Policy

  • You can take the test once every 24 hours
  • You can certify results (send to institutions) up to 3 times per 30 days
  • Each test costs $65 USD

Documents Needed on Test Day

Keep these ready before you start:

  • Your valid ID (passport, national ID, or driver's license)
  • Your login credentials for englishtest.duolingo.com
  • A glass of water (you can drink during breaks)

That's it. No admission ticket. No confirmation printout. No pencils or paper.

Requirements by Country

The test requirements are the same worldwide — there are no country-specific rules for taking the DET itself.

However, university acceptance of DET scores varies:

  • USA: Widely accepted at 5,000+ institutions
  • Canada: Accepted at most universities, but check individual programs
  • UK: Accepted by many universities, though some still prefer IELTS
  • Australia: Growing acceptance, but verify with your target institution

Always confirm with your specific institution before booking your test.
