Therefore, it is crucial to check the specific requirements of the institution or organization you are applying to before deciding which test to take.

Test Structure and Content

TOEFL

The TOEFL iBT consists of four sections: reading, listening, speaking, and writing. The test takes approximately 3 to 4 hours to complete. The reading section has 30 to 40 questions based on 3 to 4 passages, and the listening section has 28 to 39 questions based on audio clips. The speaking section consists of 4 tasks, and the writing section consists of 2 tasks.

Duolingo English Test

The Duolingo English Test is an adaptive online test that takes approximately 1 hour to complete. The test consists of a series of questions that adjust in difficulty based on the test taker’s responses.

There is no fixed number of questions or tasks, as the test adapts to the test taker’s performance. The test includes a variety of question types, including multiple-choice, fill in the blanks, and speaking and writing tasks.

Which Test is More Widely Accepted?

The TOEFL iBT is one of the most widely accepted English language tests globally, accepted by over 11,000 universities and institutions in more than 150 countries.

The Duolingo English Test is relatively new, but its acceptance is growing rapidly. It is currently accepted by over 3,000 institutions worldwide.

However, it is essential to check the specific requirements of the institution or organization you are applying to, as some may have a preference for one test over the other.

Convenience and Flexibility

TOEFL

The TOEFL iBT is offered at test centers worldwide, and there is also a home edition available, which allows test-takers to take the test from the comfort of their own homes. The home edition is identical in content, format, and scoring to the test center version. However, not all test takers may find the home edition suitable, as it requires a quiet, private space and a reliable internet connection.

Duolingo English Test

The Duolingo English Test is entirely online and can be taken from any location with a stable internet connection. This makes it a more convenient and flexible option for many test-takers. However, it’s essential to consider that the test requires a quiet and private space, as the test-taker’s environment is monitored during the test.

Preparation and Study Materials

TOEFL

There are a wide variety of study materials available for the TOEFL iBT, including official guidebooks, practice tests, and online resources. The official TOEFL website offers a range of free and paid resources, including sample questions, practice tests, and interactive online courses. Many language schools and online platforms also offer TOEFL preparation courses.

Duolingo English Test

Duolingo provides a range of free study materials on its website, including sample questions, practice tests, and test tips. Since the Duolingo English Test is relatively new, there may not be as many preparation resources available compared to the TOEFL iBT. However, the official Duolingo website provides a good starting point for test preparation.

Conclusion: Which Test Should You Take?

The decision on which English proficiency test to take depends on several factors, including the specific requirements of the institution or organization you are applying to, your budget, and your preference for test format and delivery. Both the TOEFL iBT and the Duolingo English Test are widely accepted and provide a valid and reliable assessment of English language proficiency. Ultimately, the best test for you will depend on your individual circumstances and needs.
