Compared with TOEFL

The Duolingo English Test (DET) and the Test of English as a Foreign Language (TOEFL) are two widely recognized assessments of English language proficiency, and they differ in several aspects:

1. Examination Format:

- DET: It is an online test that candidates can take from home using a computer and webcam, without the need to go to a test center.

- TOEFL: It is usually taken at a test center but also offers an online version, TOEFL iBT Home Edition.

2. Examination Duration:

- DET: The test is relatively short, taking about 45 to 60 minutes.

- TOEFL: The test is longer, typically requiring about 3 to 4 hours.

3. Examination Fee:

- DET: The registration fee is lower, at $49.

- TOEFL: The fee is higher, usually ranging from $180 to $300, depending on the location of the test.

4. Result Timing:

- DET: Results are quick, with candidates typically receiving their scores within 48 hours, and expedited services can provide them within 12 hours.

- TOEFL: It usually takes 4 to 8 days to receive the scores.

5. Frequency of Examination:

- DET: Offers more frequent testing opportunities, with the possibility of taking the test every day.

- TOEFL: Has set test dates, with about 50 to 60 prescheduled test dates per year.

6. Content of Examination:

- DET: Uses computer-adaptive technology, with question difficulty adjusting according to the candidate's level.

- TOEFL: Includes four sections: listening, reading, speaking, and writing, without adaptive testing technology.

7. Recognition:

- DET: Recognized by more than 4,500 institutions and programs worldwide.

- TOEFL: Recognized by over 11,000 colleges and other institutions globally, including universities in Australia, Canada, New Zealand, the UK, the USA, and across Europe and Asia.

8. Examination Structure:

- DET: The questions are shorter, with no long reading sections, and note-taking is not allowed during the test.

- TOEFL: Includes a longer listening section that requires note-taking.

9. Practice Tools:

- DET: Offers unlimited practice questions with instant scoring and feedback to help candidates improve their scores.

- TOEFL: There are many practice materials available, but none provide the same level of instant feedback as the DET.

10. Versions of Examination:

- DET: There are no different versions of the test available.

- TOEFL: Offers both an internet-based test (iBT) and a paper-based test (PBT).

Candidates should consider their specific circumstances, including the requirements of their target institutions, personal preferences, scheduling, and availability of the test when choosing which exam to take.
