IELTS vs. TOEFL vs. Duolingo: Which Is Better for 2026/2027 Study Abroad Applications?

If you’re applying to study abroad for the 2026/2027 academic year, you may need to demonstrate your English proficiency as part of the admission process.

But which test should you choose?

IELTS, TOEFL, and the Duolingo English Test (DET) are widely recognized English-proficiency options, but they are not interchangeable everywhere. The right choice depends on your target university, degree program, country, budget, preferred test format, and application deadline.

Before registering for any test, always confirm which examinations your specific university and program accept.

1. Cost Comparison for 2026/2027

Test fees vary by country, test center, taxes, exchange rates, and booking arrangements, so published prices can change.

For students applying from Nigeria, the approximate costs may look like this:

• IELTS Academic: Often around ₦290,000–₦310,000, depending on the test provider and current local pricing.
• TOEFL iBT: Often around ₦330,000–₦360,000 or the applicable local equivalent, depending on registration and exchange rates.
• Duolingo English Test: Generally significantly less expensive than IELTS or TOEFL, with pricing set in USD and converted according to the payment method and current exchange rate.

Because fees change, check the official test provider’s current price before budgeting for your application.

Which Is More Affordable?

For many applicants, Duolingo is the lower-cost option.

However, price should not be the only consideration. A cheaper test is not useful if your target university, scholarship, professional program, or immigration route does not accept it.

2. Test Format and Experience

The three examinations have different formats, which can significantly affect your preparation strategy.

IELTS

IELTS Academic evaluates listening, reading, writing, and speaking.

The speaking component is conducted separately from the other sections and may involve a live examiner, depending on the test format and location.

IELTS can be taken in paper-based or computer-delivered formats at participating locations.

Best suited to: Students who are comfortable with a structured four-skill examination and want a widely recognized qualification.

TOEFL iBT

TOEFL iBT focuses heavily on academic English and integrates skills across its sections.

The test is computer-based, and applicants should be comfortable listening to academic material, reading university-level passages, writing, and speaking into a computer.

Best suited to: Students who prefer computer-based testing and are targeting universities that specifically accept TOEFL.

Duolingo English Test

The Duolingo English Test is an online, computer-adaptive English assessment that can be taken remotely, subject to the test’s current rules and technical requirements.

Its shorter format and online delivery can make it convenient for applicants who need flexibility.

Best suited to: Students whose target institutions accept DET and who want a shorter, more flexible testing experience.

3. Acceptance and Recognition

Acceptance is one of the most important factors when choosing an English test.

IELTS

IELTS has broad international recognition and is accepted by many universities and other organizations worldwide.

It is also commonly used for certain immigration and professional purposes.

However, university admission and immigration requirements are not the same thing. A university may accept IELTS Academic while an immigration authority may require a particular IELTS test or score for a specific visa pathway.

TOEFL

TOEFL iBT is widely accepted by universities around the world, particularly in the United States.

Many institutions also recognize TOEFL for international admissions in Canada, Europe, Asia, and elsewhere.

The important question is not whether TOEFL is “accepted worldwide,” but whether your specific institution and program accept it.

Duolingo English Test

DET is now accepted by many universities and programs internationally, including institutions in the United States, Canada, the United Kingdom, Australia, and other countries.

However, acceptance is not universal.

Some universities, departments, scholarship programs, professional courses, or immigration authorities may not accept DET.

Always verify the current policy before choosing it.

4. Which Test Should You Choose?

Rather than choosing based solely on popularity, match the test to your application requirements.

Applying to the United States?

TOEFL or Duolingo may be suitable if your target universities accept them.

IELTS is also accepted by many U.S. universities, so don’t assume that TOEFL is your only option.

Applying to the UK?

IELTS Academic is widely recognized for university admissions, but other tests may also be accepted by individual universities.

If your application involves a visa requirement, check whether you need a specific UKVI-approved English test rather than assuming that any IELTS result will satisfy the immigration requirement.

Applying to Canada?

IELTS, TOEFL, and DET are all accepted by many Canadian universities.

Requirements vary by institution and program, so check the exact admissions page for your intended course.

Applying to Australia or New Zealand?

IELTS and TOEFL are widely used, while some institutions also accept DET.

If you are applying for a visa, make sure you distinguish between university admission requirements and current immigration requirements.

Applying Across Several Countries?

If you’re applying to universities in several countries, IELTS can be a practical choice because of its broad recognition.

However, if every university on your shortlist accepts DET, the lower cost and online format may make Duolingo attractive.

5. What If You Have a Very Short Deadline?

The Duolingo English Test can be convenient for applicants who need a relatively quick testing and results process.

However, do not choose a test solely because you have heard that results are available quickly.

Check:

• The current result-processing time
• Whether your university accepts the test
• Whether the university accepts the score for your particular program
• Whether scores must be received before your application deadline
• Whether additional verification could affect your timeline

If your deadline is close, verify all of this before paying for the test.

6. Which Test Is Best for Budget-Conscious Students?

If cost is your primary concern, the Duolingo English Test may be the most economical option among the three.

It can also eliminate some of the travel and test-center costs associated with in-person examinations.

But there is an important rule:

Never choose an English test simply because it is cheaper. Choose it because your target institution accepts it.

Paying for an inexpensive test that your university does not recognize can ultimately cost more because you may have to take another examination.

8. Don’t Confuse University Admission With Immigration

This is one of the most important points for international students.

A university may accept a particular English test for admission, while an immigration authority may have different requirements for a student visa or later immigration pathway.

For example, a university could accept the Duolingo English Test for admission while a particular visa application requires a different approved English-language test.

Therefore, check two separate sets of requirements:

University Requirements

Confirm:

• Accepted English tests
• Minimum overall score
• Minimum section scores
• Test validity period
• Program-specific requirements
• Application deadline

Immigration Requirements

If you also need an English test for a visa or immigration process, check the relevant government authority’s current requirements separately.

9. How to Choose Your Test

Use this simple process before registering.

Step 1: Create Your University List

Write down every university and program you plan to apply to.

Step 2: Check Accepted Tests

Visit the official admissions page for each program and record which tests are accepted.

Step 3: Compare Minimum Scores

Don’t only check the overall score. Some programs also impose minimum scores for individual sections.

Step 4: Check Deadlines

Make sure you have enough time to take the test and submit your official results before each application deadline.

Step 5: Compare Your Options

If several tests are accepted, compare:

• Cost
• Test-center availability
• Online availability
• Test format
• Preparation requirements
• Result-processing time
• Whether you may need the test later for another purpose

Step 6: Register

Only register after confirming that your selected test meets the requirements of your target programs.

Final Verdict: There Is No Universal “Best” Test

For 2026/2027 study-abroad applications, IELTS, TOEFL, and Duolingo can all be useful, but the best choice depends on your individual application list.

• IELTS offers broad international recognition and may be practical for students applying across several countries.
• TOEFL is a strong option for applicants targeting universities that accept or prefer it, particularly in the United States.
• Duolingo can offer significant advantages in cost and convenience when your target institutions accept it.

Your university’s current requirements should ultimately determine your choice.

Before spending money on any examination, check the official admissions requirements for every university and program on your shortlist.
