TOEFL vs. IELTS vs. Duolingo English Test:

Which English Proficiency Test Should You Take?

Choosing the right English proficiency test is an important step in preparing for university admissions abroad. TOEFL iBT, IELTS Academic, and the Duolingo English Test (DET) all assess English proficiency, but they differ in test format, question types, scoring systems, and testing requirements.

At Trinity Scholar, we help students understand these differences so they can choose the test that best aligns with their target universities, English proficiency, and preparation goals.

TOEFL, IELTS, and Duolingo: Key Differences

Test details and reporting policies may change. Always confirm the latest requirements with the official test provider.

Do I need to take TOEFL or IELTS?

You may need to submit an English proficiency test score when applying to a university or academic programme, particularly if you do not meet the institution's English-language exemption requirements.

Whether you need TOEFL, IELTS, or another accepted test depends on your target institution, programme, educational background, and application category.

Before registering, check the official admissions requirements of every institution on your application list.

What are the main differences between TOEFL and IELTS?

Which countries prefer TOEFL or IELTS?

Neither test is exclusively preferred by a particular country.

Many universities in the United States accept both TOEFL and IELTS. Universities in the United Kingdom, Australia, Canada, and New Zealand may also accept both, depending on their admissions policies.

The most important factor is whether your target institution accepts the test and score you plan to submit. Some programmes may also specify minimum scores for individual sections.

We recommend checking the official admissions website of each institution before choosing your test.

How do TOEFL and IELTS scores compare?

Important: These are approximate score comparisons, not guarantees of equivalent performance or university admission. Different combinations of section scores can produce the same overall score, and institutions determine their own minimum requirements. Check the official score requirements for your intended programme.

How does the content differ between TOEFL and IELTS?

Which one is easier?

There is no universally easier test. The better choice depends on your English proficiency, familiarity with the question types, and ability to perform under different testing conditions.

TOEFL may suit students who are comfortable with computer-based tasks, recorded speaking responses, and the new adaptive Reading and Listening format.

IELTS may suit students who prefer interacting with an examiner during Speaking and are comfortable with its varied question types and academic writing tasks.

The best way to compare them is to try official sample questions from both exams. A diagnostic assessment can help identify which format better matches your strengths and where you need additional preparation.

Which one should I take?

Start by checking the requirements of your target universities and programmes. If they accept both TOEFL and IELTS, consider the following:

TOEFL may be a good fit if you:

• Prefer completing all four skills in a computer-based testing environment.
• Feel comfortable speaking into a microphone rather than directly to an examiner.
• Can respond effectively to short, structured tasks.
• Want to practise the specific adaptive Reading and Listening format.

IELTS may be a good fit if you:

• Prefer speaking directly with an examiner.
• Are comfortable with a range of question types, including matching and completion tasks.
• Can organise and develop written responses within the required time.
• Prefer the IELTS Academic test structure.

These are general guidelines, not strict rules. Your current proficiency, target score, available preparation time, and school requirements should all inform your decision.

How long are the TOEFL and IELTS scores valid?

TOEFL iBT scores are generally valid for two years from the test date. IELTS results are generally recommended for use within two years as well.

Can I retake TOEFL or IELTS if I do not achieve my target score?

Yes. You can retake either test, subject to the relevant registration rules and test availability.

For TOEFL, you must wait at least 3 days after your last test date before taking another test. Unlike IELTS, you cannot retake individual sections (such as just Speaking or Writing); you must re-sit the entire exam.

IELTS also offers One Skill Retake at eligible test centres for qualifying test formats and candidates. This option allows you to retake one skill rather than the entire test, generally within 60 days of the original test date. Availability and acceptance vary, so confirm eligibility with the test provider and your target institution.

Do I have to send in all my scores?

Not necessarily. Score submission policies vary by institution and programme. Some institutions allow applicants to select which scores to submit, while others may have specific reporting requirements.

Check each institution's official policy before deciding which scores to send. Do not assume that every school follows the same rules.

What should be my goal for the scores?

Your target score should be based on the requirements of the universities and programmes you plan to apply to.

Review both the overall score requirement and any minimum section scores. If you are applying to multiple institutions, create a list of their requirements and identify the highest relevant target.

If a programme does not publish a clear minimum score, contact its admissions office rather than relying on a general benchmark.

When should I start preparing for/taking the exams?

Start preparing as early as possible, especially if you need to improve your overall English proficiency as well as learn test-taking strategies.

A practical preparation plan includes:

• Diagnostic assessment: Identify your current level and areas for improvement.
• Skill development: Strengthen Reading, Listening, Speaking, and Writing.
• Test-specific practice: Learn the format, timing, and scoring criteria of your chosen exam.
• Practice tests: Build familiarity with exam conditions and monitor your progress.
• Final review: Focus on recurring errors and practise under timed conditions.

The amount of preparation time needed depends on your starting level, target score, and test date.

How do I improve my score?

Consistent practice is essential. Students should combine general English development with targeted exam preparation.

• Read: Build reading speed, vocabulary, and comprehension through articles, books, and academic texts.
• Listen: Practise with podcasts, lectures, interviews, and recordings featuring different English accents.
• Speak: Practise organising ideas, explaining opinions, and responding clearly within a time limit.
• Write: Develop paragraph structure, grammar, vocabulary, and the ability to answer the specific task.
• Review: Analyse mistakes, identify patterns, and adjust your preparation plan.

Official practice questions and experienced feedback can help you understand the demands of each exam and focus on the skills that need the most improvement.
