Duolingo English Test vs TOEFL: What Are The Differences?

If you plan on studying in prominent universities and colleges abroad, one of the requirements for admission is a language proficiency certification.

Moreover, you also need to present an English language proficiency certificate if you apply to multinational companies. It is also one of the main requirements for visa applications if you wish to migrate to an English-speaking country. 

Many test takers have different options for the language proficiency exam they will take. And the commonly used language proficiency exam is the TOEFL; however, the Duolingo English Test is now gaining popularity in providing a reliable assessment of English language skills. 

Which language exams should you take? Is the TOEFL easier than the Duolingo English Test? Or which exam is widely accepted by educational institutions? You might also consider your budget for these exams. 

In this article, we will differentiate these two language proficiency exams — Duolingo English Test and TOEFL. We will help you decide which of these two language exams is the best choice for you. 


What is the Duolingo English Test?

The Duolingo English Test is an on-demand language proficiency exam gaining more popularity because of its accessibility and dynamic approach to its test format. 

And also, the test is designed to measure the English language abilities of an individual. The Duolingo exam is only a short exam that only takes about 45 minutes to an hour for you to finish, and they also deliver fast and accurate test results in just 48 hours after you have taken the test. 

In addition, this exam is also preferred by most test-takers because they find the exam content comprehensive, convenient, and fun, unlike the traditional language proficiency exams that are already available in the market. 

Aside from the dynamic test format, the developer of the Duolingo exam also made it accessible online. It means that you can take the exam from the comfort of your home or whenever you can access it, in contrast to other language exams, where you need to go to the testing centers to take the exam. 

The Duolingo English Test is also very affordable compared to other language proficiency exams such as the TOEFL. Other than that, it is also widely recognized and accepted by different educational institutions here and abroad. 

What is the TOEFL Test?

The TOEFL (Test of English as a Foreign Language) is a highly accepted and widely recognized language proficiency exam. It is a standardized language assessment test that measures the English abilities of native and non-native English speakers. 

In addition, the TOEFL exam has two test formats, including TOEFL iBT and TOEFL PBT. These two test formats differ in exam structure and contents; however, they still assess language communication skills. 

Moreover, the TOEFL exam measures the English skills of an individual in reading, reading, listening, speaking, and writing. Many test-takers find the TOEFL exam quite challenging because it uses formal, academic language and high-level vocabulary rather than casual or conversational English. 

Most educational institutions also prefer it because the test is more inclined to use academic English in its contents. This language exam is also widely used for admissions in universities and colleges, visa applications, and work requirements for multinational companies.  

The ETS (Educational Testing Service), which developed the TOEFL exam, also recommends that the test-takers be at least 17 years old or 11th graders. It is because this language proficiency exam uses a high-level English vocabulary and passages. 


Exam Fees: Duolingo English Test vs. TOEFL

These two language proficiency exams have a significant difference in their exam fees. In addition, the Duolingo English Test only has a standard rate of USD 49, which applies to all locations in various countries where you are located.

However, the TOEFL exam fee differs per test version. For example, the TOEFL iBT exam fee is around USD 185, and the TOEFL PBT costs around USD 180. Moreover, these TOEFL exam fees vary per location across different countries worldwide. 

Regarding exam fee refunds, the Duolingo exam does offer refunds for its test fees, such as if you have failed to finish the exam or canceled the test schedule. And for the TOEFL exam, it gives refunds up to 50% of the original test fee that you paid so long as you follow their conditions for refund applications. 

Moreover, the TOEFL has additional charges under certain circumstances. For example, they have an additional fee if you have registered late for the exam. 

In addition, you also need to pay an additional fee if you wish to reschedule your test date and if you want to avail yourself of their other services.

In terms of exam duration, the Duolingo exam is shorter, which only runs for 45 to 60 minutes, compared to the TOEFL, which takes about three to four hours. There is also an additional 30 minutes check-in period in the testing center.

Exam Frequency: Duolingo English Test vs. TOEFL Exam

One of the test-takers concerns in taking a language exam is the test schedule offered by the different exam providers. In addition, most language proficiency tests have selected test dates annually, while others have weekly test schedules. 

Moreover, due to the rising demands of language proficiency exams, Duolingo has made its test very accessible to its test-takers, thus offering a daily online test schedule. However, you are only allowed to take the Duolingo exam twice a month. 

While the TOEFL also provides a four days a week test schedule that is accessible via its TOEFL Home Edition test version. Aside from this, the TOEFL exam frequency differs depending on what test version you are going to take. 

For example, if you opt to take the TOEFL iBT, it has more than 60 prescheduled test dates annually, and for its TOEFL PBT, it is only offered four times a year. 

If we compare these two language proficiency exams in terms of exam frequency, both are very convenient and accessible, providing the test-taker with more options to choose from. 

The Duolingo exam can be taken daily, and the TOEFL Home Edition using your computers at home. If you prefer the TOEFL iBT and PBT, they have 4500 testing centers worldwide. 

In addition, the TOEFL exam is also accepted in 190 countries, reaching more individuals in different areas globally. In contrast, the Duolingo exam is only accepted in 65 countries.

Scoring Difference: Duolingo English Test vs. TOEFL

One of the key features of the Duolingo English Test is its computerized scoring system, and it is also known to deliver fast results within 48 hours. In addition, the Duolingo test scores can also be interpreted using the Common European Framework of Reference for Languages (CEFR)

On the other hand, the TOEFL exam is also scored using a centralized scoring network that is never done at the testing centers to avoid misinterpretations of human raters and ensure consistency and reliability. 

For example, the computer is the one that processes and scores the TOEFL reading and listening test sections. At the same time, the writing and speaking test sections are scored by both highly trained TOEFL exam raters and an automated AI scoring system. 

In addition, the TOEFL has different raw scores per test section, and it is then computed to get the scaled score. Unlike Duolingo, it only has an overall score directly converted to its corresponding CEFR proficiency levels. 

Moreover, these language proficiency exams use the CEFR scale as their benchmark for an accurate assessment. However, they differ in terms of their overall scoring scale. For example, Duolingo’s highest test score is 160 points, and its lowest is 30. 

And as for the TOEFL, the highest possible score is 120 points, and the lowest score is around 8 to 1 point. So if we compare the highest score of the Duolingo and TOEFL, it is equivalent to the CEFR C2 proficiency level.

Test Requirements: Duolingo English Test vs. TOEFL Exam

These two language proficiency exams have different test requirements. If we look into the age requirement of the Duolingo exam, they have imposed a minimum age requirement of 13 years old. 

However, they still accept test-takers below that age level, but parental consent should be presented. In contrast, the TOEFL exam does not have an age requirement, but they highly recommend that the test-takers be at least 17 years old or in the 11th grade. 

The TOEFL exam is quite challenging and uses complex English terms that are usually encountered in the 11th grade. In addition, they also require parental consent for those who are under 15 years old. 

One of the test requirements of Duolingo is for you to have a computer with a front-facing camera, microphone, and speakers that are working efficiently. Which is a big difference compared to the TOEFL exam, wherein you take it in their official testing centers.
