Duolingo English Test Attempts, Credits and Retakes

When you purchase a Duolingo English Test (DET) credit, you are permitted up to three attempts to complete and upload your test session.

When you purchase a Duolingo English Test (DET) credit, you are permitted up to three attempts to complete and upload your test session. However, only one certified result is issued per credit. This means that even if you use all three attempts, you will only receive one official, shareable score if you successfully complete the test and meet all requirements.

Key takeaways

  • Starting the test counts as an attempt, and two rule violations can expire a credit before all three starts are used.
  • A purchased DET credit can allow up to three starts but only one certified result.
  • Certified results remain valid for two years and cannot be shared or viewed as a certificate after expiry.
  • Appeal eligibility, technical retakes and rule-violation outcomes are different processes.
  • One DET credit allows up to three attempts to complete and upload the test session, but only one certified result.

How many attempts does one DET credit allow?

The number of attempts is subject to technical and rule outcomes. For example, technical issues or rule violations can affect how many attempts you actually use or whether your credit remains valid. Source

What counts as an attempt on the Duolingo English Test?

Each time you start the test, it counts as one attempt, regardless of whether you finish or upload the session. This is important: simply beginning the test uses one of your three permitted attempts for that credit. If you encounter technical problems or need to restart, each new start will count as another attempt.

If you use all three attempts without successfully completing and uploading a session that meets all requirements, your credit will expire and you will not receive a certified result for that credit.

Rule violations and credit expiry

Rule violations are taken seriously by Duolingo. If you violate the test rules twice, your DET credit can expire before you have used all three attempts. This means you could lose your chance to obtain a certified result even if you have not started the test three times.

Rule violations can include, but are not limited to, prohibited behaviors during the test session. The official DET rule consequences page provides further details.

Appeals, technical retakes, and rule-violation outcomes are handled as separate processes. Not all situations will qualify for an appeal or technical retake, and the decision rests with Duolingo and the receiving institution.

Certified result validity and sharing

A certified DET result is valid for two years from the date of issue. After this period, the result cannot be shared or viewed as a certificate. If you need to provide proof of English proficiency beyond this window, you will need to take the test again and obtain a new certified result.

Only one certified result is issued per DET credit, regardless of how many attempts you use. If you do not complete a successful attempt within your three allowed starts, you will not receive a certified result for that credit.

Checklist: Steps before and after your DET attempt

  1. Confirm the DET requirements of your receiving institution or organisation.
  2. Purchase a DET credit from the official Duolingo English Test website.
  3. Prepare your test environment and review the DET rules to avoid violations.
  4. Start your first attempt, ensuring all technical requirements are met.
  5. If you encounter issues, use your remaining attempts as needed, but remember each start counts.
  6. Avoid rule violations to prevent early expiry of your credit.
  7. After completing a successful attempt, wait for your certified result.
  8. Share your certified result with your chosen institution within two years of the test date.
  9. If you do not receive a certified result, review the official guidance on appeals or technical retakes.

Scenario: Using all DET credit attempts

Suppose you purchase one DET credit. On your first attempt, you experience a technical issue and cannot complete the test. You start a second attempt, but accidentally violate a test rule. You begin a third attempt, but violate another rule. According to the official policy, two rule violations can expire your credit before all three starts are used. In this scenario, you would not receive a certified result, and your DET credit would be expired.

This example shows the importance of understanding both the technical and rule-based limitations on DET attempts and credits.
