IELTS vs Duolingo English Test – Which One Should Kazakhstan Students Choose
- May 11
- 5 min read
Choosing the right English proficiency test is a crucial step for students in Kazakhstan aiming to study abroad or improve their academic and professional prospects. Two popular options are the IELTS test and the Duolingo English Test (DET). Both have their strengths and weaknesses, and understanding these can help students make an informed decision.
This article compares the Duolingo English Test and IELTS in detail, covering their formats, scoring systems, acceptance by universities, preparation methods, costs, and accessibility. It also offers strategic advice on which test suits different goals best.
Duolingo English Test Overview
The Duolingo English Test is a modern, fully online English proficiency exam designed to assess reading, writing, speaking, and listening skills. It has gained popularity for its convenience and affordability.
What is the Duolingo English Test?
The Duolingo English Test is an adaptive, computer-based exam that evaluates English language skills through a variety of question types. It is taken entirely online, allowing students to complete it from home or any quiet, private space with a reliable internet connection.
The test lasts about 60 minutes and includes tasks such as:
Typing sentences based on spoken prompts
Reading and completing missing words
Speaking short answers into a microphone
Writing short essays
Online Exam System
Unlike traditional exams, the Duolingo English Test does not require a physical test centre. Students register online, verify their identity with a government-issued ID, and take the test under remote proctoring. This system offers flexibility, especially for students in Kazakhstan who may not have easy access to test centres.
Adaptive Testing
The test adapts to the test taker's ability level. If a student answers a question correctly, the next question becomes slightly harder. If they answer incorrectly, the next question is easier. This adaptive format helps provide an accurate measure of English proficiency in a shorter time.
IELTS vs Duolingo Comparison
Both the IELTS test and the Duolingo English Test assess English skills but differ significantly in format, difficulty, and recognition.
Difficulty Level
The IELTS test is generally considered more challenging. It includes four sections: Listening, Reading, Writing, and Speaking. The speaking part is a live interview with an examiner, which can be intimidating but offers a realistic assessment of conversational skills.
The Duolingo English Test is shorter and uses automated scoring. Its adaptive nature means questions adjust to the test taker's level, which some find less stressful. However, it may not test speaking skills as deeply as IELTS.
Score Systems
Understanding how scores work in both tests helps students interpret their results and meet university requirements.
IELTS Score
IELTS scores range from 0 to 9 for each section, with an overall band score calculated as the average. Scores reflect proficiency levels from non-user (0) to expert (9).
Duolingo English Test Score
DET scores range from 10 to 160. The score reflects overall English ability, with higher scores indicating better proficiency.
Score Conversion
Many universities provide conversion charts to compare IELTS scores with Duolingo scores. For example:
| IELTS Band | Approximate Duolingo Score |
|------------|----------------------------|
| 9.0 | 160 |
| 8.0 | 145 |
| 7.0 | 120 |
| 6.0 | 95 |
| 5.0 | 75 |
This conversion helps students understand which test score meets their target institution's requirements.

Acceptance by Universities
Choosing a test also depends on which universities accept it.
Countries Accepting IELTS and Duolingo
IELTS is widely accepted by universities in the UK, Australia, Canada, the USA, and many other countries. It is often the preferred test for academic admissions and visa applications.
The Duolingo English Test is gaining acceptance, especially due to its convenience during the COVID-19 pandemic. Many universities in the USA, Canada, and some in the UK now accept DET scores. However, it is less universally accepted than IELTS.
Advantages for Kazakhstan Students
For students in Kazakhstan, the Duolingo English Test offers easy access without travel or scheduling challenges. It is also faster to receive results, often within 48 hours.
IELTS, especially the IELTS Academic version, remains the gold standard for many scholarship programs and competitive university admissions. It provides a more detailed assessment of academic English skills.
Practice and Preparation
Preparation is key to success in any English test.
IELTS Practice
IELTS preparation involves practising all four skills with sample tests, mock exams, and sometimes coaching. Many students benefit from structured courses that include IELTS practice materials and simulated IELTS tests.
Duolingo English Test Preparation
DET preparation focuses on familiarising with the test format and practising adaptive question types. Since the test is shorter and adaptive, preparation can be more flexible and less time-consuming.
Adaptive Test System vs Traditional Tests
The adaptive system of the Duolingo test means students should be comfortable with a variety of question types and quick responses. IELTS preparation often requires more extensive writing and speaking practice.
Cost and Accessibility
Cost and ease of access are important factors for students.
Exam Fees
IELTS test fees in Kazakhstan typically range from 25,000 to 35,000 KZT.
The Duolingo English Test costs about $49 USD (approximately 22,000 KZT), making it more affordable.
Availability
IELTS tests are held at designated centres in major cities, with limited dates. The Duolingo English Test can be taken anytime, anywhere with internet access.

Strategy: Which One Should You Choose
Choosing between IELTS and Duolingo depends on your goals and circumstances.
Based on Your Goal
If you aim for top universities in the UK, Australia, or Canada, IELTS Academic is often required.
For quick admission processes or if you need a flexible, affordable option, the Duolingo English Test is a good choice.
Study Abroad Plans
For countries and universities that accept both, consider your preparation time, budget, and comfort with test formats.
If you plan to apply for scholarships or competitive programs, IELTS scores may carry more weight.
