All 19 Duolingo English Test Question Types for 2025Understanding Language Proficiency Tests: Duolingo and IELTS
When planning to study at New Zealand universities, demonstrating English language proficiency is often a requirement for international students. Two popular tests for proving English proficiency are the Duolingo English Test (DET) and the International English Language Testing System (IELTS). Understanding the differences between these tests and how they align with university requirements is crucial.
The Duolingo English Test (DET)
The Duolingo English Test is known for its accessibility and convenience. It is an online test that can be taken from anywhere with a reliable internet connection. The test is shorter, typically lasting around an hour, and the results are available within 48 hours. One of the main advantages of Duolingo is its affordability compared to traditional tests like IELTS.
Duolingo assesses a wide range of English skills, including reading, writing, speaking, and listening, through various interactive questions. For example, you might be asked to complete a sentence with the correct word or write a short essay on a given topic. You'll also listen to spoken sentences and then type what you hear to demonstrate listening skills.
The International English Language Testing System (IELTS)
IELTS is a more established test widely accepted by universities around the world, including those in New Zealand. It evaluates English proficiency through four modules: Listening, Reading, Writing, and Speaking. The IELTS test typically takes about 2 hours and 45 minutes to complete, as each module is rigorously timed.
For instance, in the Writing section, candidates might be required to describe a graph or write a detailed essay based on a prompt. In the Speaking module, there is a one-on-one interview with an examiner, where candidates answer questions on familiar topics, speak on a given topic, and engage in a two-way discussion.
How Universities View Duolingo vs IELTS
When aiming to meet the English language requirements for New Zealand universities, it's important to verify which tests are recognized by your chosen institution. While IELTS has long been recognized as a standard, many universities are now accepting Duolingo scores. However, the acceptance levels may vary. For example, a university might accept a Duolingo score of 115 but require an IELTS band score of 6.5.
Choosing Between Duolingo and IELTS
Consider your strengths when deciding between the two. If you are comfortable with face-to-face speaking and detailed writing tasks, IELTS might be the better option. Conversely, if you prefer a test that you can take from home with quicker results, Duolingo could be more suitable. Researching the specific requirements of your university will also guide your decision.

Key Differences Between Duolingo and IELTS Tests
When deciding between the Duolingo English Test (DET) and the International English Language Testing System (IELTS) for university admission in New Zealand, it's essential to understand their distinct characteristics and what they measure.
Test Format and Structure
Duolingo is a highly flexible online test that can be accessed from any location with internet access. The test duration is approximately 60 minutes, assessing four core English skills: reading, writing, speaking, and listening, often through engaging, interactive questions. For example, a typical exercise might involve filling in the blanks in a sentence or verbally describing an image that appears on your screen.
IELTS, on the other hand, is a paper-based or computer-based exam widely conducted in authorized test centers. It lasts around 2 hours and 45 minutes, administering a separate module for each skill: Listening, Reading, Writing, and Speaking. A distinct feature of IELTS is the Speaking test, where candidates engage in a live interview with an examiner—a setting that assesses verbal communication under real-world conditions.
Scoring System
Duolingo's scoring is out of 160, with results typically available within two days. A score of 105-110 might be equivalent to an IELTS band score of 6.5, but this comparison can vary based on university requirements.
IELTS scores range from 0 to 9, with each skill receiving a band score, and the overall score being an average of these. A band score of 6.5 generally indicates a competent level of English suitable for academic study.
Test Cost and Accessibility
Duolingo is notably more affordable, usually costing around USD 49, which makes it an attractive option for budget-conscious students. Its online nature allows for easy scheduling and the convenience of taking the test from home.
IELTS typically costs more, around USD 215 to USD 250, reflecting its established presence and the detailed assessment it offers. Although it may require travel to a testing location, resulting in additional costs, this test is preferred by many institutions due to its rigorous and personal assessment style.
Duolingo Test PracticeAcceptance by Universities
While IELTS has been a longstanding requirement for many universities and is largely preferred due to its comprehensive nature, Duolingo is gaining traction, especially in regions where testing centers may not be easily accessible. However, acceptance of these scores can vary widely between institutions. For instance, University A in New Zealand might accept a Duolingo score of 115 but require an IELTS score of 6.5, whereas University B might not accept Duolingo at all.
In conclusion, the choice between Duolingo and IELTS will depend on personal circumstances, university requirements, and comfort with each test's format and environment.
Acceptance of Duolingo and IELTS in New Zealand Universities
When considering New Zealand universities, the acceptance of English proficiency tests such as the Duolingo English Test (DET) and the International English Language Testing System (IELTS) can significantly influence your choice.
Growing Recognition for Duolingo
In recent years, the Duolingo English Test has gained wider acceptance among New Zealand universities. Its cost-effectiveness and convenience appeal to both students and institutions. For instance, universities like the University of Waikato and Massey University are among those that accept Duolingo scores. They generally require a score ranging from 110 to 120, depending on the program. It's important to verify the specific requirements for the university and course you are applying to, as they can specify different benchmarks. For example, a course in Humanities might accept a Duolingo score of 115, while a more competitive course in Science might set the threshold at 120.
Established Preference for IELTS
IELTS remains a traditional choice, given its widespread recognition and long-standing reputation. Most New Zealand universities, including the University of Auckland and Victoria University of Wellington, require an IELTS band score between 6.0 and 7.0 for undergraduate and postgraduate courses. The rigorous assessment strategy of IELTS, especially the face-to-face Speaking test, is often highly valued in academic circles for its detailed evaluation of real-world communication skills. For example, an IELTS band score of 6.5 is typically suitable for courses in Business, while a band score of 7.0 might be needed for more rigorous academic programs such as Medicine or Law.
Comparative Insights
When deciding between Duolingo and IELTS based on their acceptance by New Zealand universities, it's crucial to consider both program-specific and university-wide standards. Some universities might treat them interchangeably, while others might have a clear preference. For example, a highly competitive Master's program may prefer the detailed appraisal provided by IELTS scores to ensure candidates meet stringent language proficiency standards.

Navigating University Preferences
Prospective students should thoroughly research and confirm with their chosen university's admissions office to understand which test best fits their application needs. Checking official university websites, contacting admissions counselors, and utilizing university-specific resources can provide clarity. Additionally, reaching out to current students or alumni through online forums and social media platforms can offer practical insights into how language proficiency tests impact the admissions process.

How to Choose the Right Test for Admission to New Zealand Universities
When selecting the appropriate English proficiency test for admission to New Zealand universities, it’s essential to consider several factors to ensure that your choice aligns with your goals and circumstances.
Cost Considerations
Financial constraints can greatly influence your decision. Duolingo, priced at about USD 49, is an attractive option for those on a budget. For instance, if you're applying to multiple programs or need to re-take the test, Duolingo's lower cost can save you hundreds of dollars compared to IELTS, which typically costs between USD 215 to USD 250.
Test Format and Convenience
If flexibility and convenience are priorities, Duolingo’s online format allows you to take the test at any time and from any location with a reliable internet connection. This eliminates the need to travel to a test center, making it suitable for those with busy schedules or residing in remote areas. Conversely, IELTS requires attendance at designated test centers, which might constrain your movement and time availability.
Improve Your EnglishSpeed of Results
Urgency in obtaining test results can steer your decision. Duolingo offers results within 48 hours, which is beneficial if application deadlines are near. In contrast, IELTS results are typically available after 13 days, which might not be ideal if you need to make quick application decisions.
Acceptance by Universities
While Duolingo's acceptance is growing, particularly in universities like the University of Waikato and Massey University, IELTS maintains broader recognition across all New Zealand institutions. For example, if you’re applying to highly competitive or prestigious programs, it might be safer to opt for IELTS due to its universal acceptance.
Assessment Depth
Consider how comfortable you are with the test's evaluation style. Duolingo's automated assessment might be less intimidating but may not provide as comprehensive an evaluation as IELTS, especially in speaking skills. IELTS's in-person speaking assessment could be beneficial if you're confident in face-to-face communication and need to demonstrate your skills in realistic settings.
Program-Specific Requirements
Directly consult with the admissions office of your desired program. Some programs may specify a preference or requirement for one test over the other. For instance, a Business course might require an overall strong proficiency level, which can be effectively demonstrated through IELTS’s detailed score report.
Ultimately, the choice between Duolingo and IELTS should reflect your personal circumstances, financial situation, and the precise requirements of the universities and programs you are targeting.
