What Are TOEFL, PTE, Duolingo, IELTS? Overview of English Proficiency Tests

These four tests serve as gateways for international students, professionals, and immigrants seeking to prove their English language competency. TOEFL, or the Test of English as a Foreign Language, was developed by the Educational Testing Service and has been the benchmark for academic English assessment for decades. It is particularly favored by institutions in the United States and Canada, with acceptance at over 11,000 universities and colleges globally.

IELTS, the International English Language Testing System, is jointly managed by the British Council, IDP Education, and Cambridge Assessment English. It offers two versions: Academic for university admissions and General Training for immigration purposes. IELTS is the preferred choice in the United Kingdom, Australia, New Zealand, and many European countries.

PTE Academic, created by Pearson, is entirely computer-based and appeals to test-takers who prefer technology-driven assessments. It delivers results within two to five days and has gained substantial traction in Australia, New Zealand, and the UK, particularly for visa applications and permanent residency pathways.

The Duolingo English Test represents the newest option in this space. Launched as a fully online, on-demand test, it can be taken from home at any time with results delivered in just 48 hours. Currently accepted by approximately 5,500 institutions worldwide, including 95 of the top 100 US universities, Duolingo has rapidly gained credibility for its affordability and convenience. The test costs only $59, making it the most budget-friendly option available.

Your choice depends primarily on where you plan to study or work, your budget, how quickly you need results, and your comfort level with different test formats.

Exam Pattern and Test Format: Sections, Question Types, Test Duration

Understanding the structure of each test helps you prepare effectively and choose the format that matches your strengths.

TOEFL consists of four distinct sections: Reading, Listening, Speaking, and Writing. The entire test takes approximately two hours to complete. All sections are delivered via computer, and the test is available at official test centers as well as through the TOEFL iBT Home Edition. The Reading section includes academic passages followed by comprehension questions. Listening involves lectures and conversations. Speaking requires you to respond to prompts using a microphone, and Writing includes both integrated and independent essay tasks.

PTE Academic divides the test into three main parts: Speaking and Writing combined, Reading, and Listening. The total duration ranges from two to two and a half hours. This test is fully automated and computer-based, meaning you interact exclusively with the machine from start to finish. Question types include read-aloud exercises, essay writing, multiple-choice comprehension, and fill-in-the-blank tasks.

IELTS offers both paper-based and computer-delivered formats. The test includes four sections: Listening, Reading, Writing, and Speaking, totaling approximately two hours and 45 minutes. One unique aspect of IELTS is that the Speaking section is conducted as a face-to-face interview with a certified examiner, which many test-takers find more natural and less intimidating than speaking into a computer.

The Duolingo English Test stands apart with its adaptive format. The test adjusts question difficulty in real time based on your performance, creating a personalized assessment experience. It takes only one hour to complete and covers integrated skills through varied question types such as read-and-select, listen-and-type, speak-about-the-photo, and video interviews. You can take the Duolingo test entirely from home using a computer with a webcam and stable internet connection.

Scoring Systems and Score Conversion: TOEFL 120, IELTS Bands 0–9, PTE 10–90, Duolingo 10–160

Each test uses a unique scoring scale, but all are anchored to the Common European Framework of Reference for Languages, making conversions possible.

TOEFL scores range from 0 to 120, with each of the four sections contributing up to 30 points. Most competitive universities require scores between 90 and 100, though top-tier institutions may expect 100 or higher.

IELTS uses a band system from 0 to 9, with half-point increments allowed. Each skill receives an individual band score, and these are averaged to produce an overall band score. A score of 6.5 to 7.0 is typically required for admission to reputable universities.

PTE scores run from 10 to 90, with most universities setting minimum requirements between 60 and 65 for undergraduate programs and slightly higher for graduate studies.

Duolingo scores span from 10 to 160. Leading institutions generally require scores of 110 to 120 for admission. According to conversion tables, a Duolingo score of 120 roughly equates to an IELTS 6.5 or a TOEFL 95.

Here is a comparison of typical minimum score requirements:

Always verify score requirements directly with your target institutions, as they can vary significantly by program and department.

Acceptance by Country and Universities: USA, Canada, UK, Australia, Germany

Acceptance patterns differ by region and institution type, making it essential to match your test choice with your destination.

For the United States, TOEFL remains the most widely accepted and trusted test, recognized by virtually all universities and colleges. Duolingo has seen explosive growth in recent years and is now accepted by 95 of the top 100 US universities, particularly for undergraduate and master’s programs in fields like business, engineering, and computer science. IELTS is also accepted at most American institutions, though TOEFL tends to carry slightly more weight in admissions decisions. PTE has limited but growing acceptance in the US market.

In Canada, IELTS is often the preferred choice, especially for immigration programs like Express Entry and the Student Direct Stream. However, TOEFL, PTE, and Duolingo are widely accepted by Canadian universities for academic admissions.

The United Kingdom traditionally favors IELTS, which is accepted across all UK universities and is required for many visa categories. PTE is increasingly recognized for both university admissions and UK work visas. Duolingo acceptance is growing but should be verified on a case-by-case basis. TOEFL is generally accepted but less common than IELTS in the UK context.

Australia and New Zealand strongly prefer IELTS and PTE, especially for permanent residency and skilled migration pathways. IELTS is required for many Australian student visas, while PTE is popular due to its fast results and full acceptance by the Department of Home Affairs. TOEFL is accepted by most universities, but IELTS and PTE dominate the market.

In Germany and other European countries, IELTS and TOEFL are both widely recognized for university admissions. Duolingo is gaining acceptance at select institutions, particularly for programs taught in English.

Before committing to a test, visit your target university’s official admissions website to confirm which tests they accept and what minimum scores they require.

Test Availability, Dates, At-Home Options, Results Timeline

Flexibility in scheduling and receiving results can be critical, especially when facing tight application deadlines.

TOEFL is offered more than 60 times per year at authorized test centers around the world. The TOEFL iBT Home Edition allows you to take the test remotely with live proctoring. Results are typically available within four to eight days after the test date.

PTE Academic is available year-round at numerous computer-based testing centers. You can schedule your test with as little as 24 hours’ notice, and PTE also offers an online version called PTE Academic Online. Results are delivered in two to five days, making it one of the fastest options available.

IELTS test dates are offered multiple times each month at test centers worldwide. Both paper-based and computer-delivered formats are available, though the face-to-face Speaking component remains standard. Results are released within three to 13 days, depending on the format chosen. IELTS Indicator, an online test, was introduced during the pandemic but has limited acceptance.

Duolingo is the most flexible option, available 24 hours a day, seven days a week. You can take the test from your home at any time, provided you have a computer with a webcam, microphone, and reliable internet connection. Results are sent within 48 hours, the fastest turnaround of any major English proficiency test. This makes Duolingo ideal for last-minute applications or students in remote areas with limited access to test centers.

Exam Fee, Payment Methods, Rescheduling and Retake Policies

Cost and flexibility matter, especially for students managing tight budgets.

TOEFL costs approximately $195 USD globally, though the fee varies slightly by country. In India, the fee is around INR 16,900. Rescheduling costs an additional $60, and you must wait at least three days between test attempts. Payment can be made via credit card, debit card, or other approved methods on the official ETS website.

PTE Academic fees are roughly $200 USD or INR 18,000 in India. Rescheduling incurs a fee, and you can retake the test after five days if needed. Payment options include major credit and debit cards.

IELTS is the most expensive option, with fees ranging from $215 to $250 USD depending on location. In India, fees are approximately INR 16,000 to INR 17,000. There is no mandatory waiting period for retakes, and rescheduling is permitted with applicable fees. Payment can be made online or at test centers.

Duolingo is by far the most affordable at just $59 USD, roughly INR 5,000 to INR 6,000. You are allowed to take the test twice within any 30-day period, and there are no rescheduling fees since the test is on-demand. Payment is accepted via major credit cards, debit cards, and PayPal, making it accessible to students worldwide.

Here is a fee comparison:

Difficulty Level and Best Test by Profile: College Students, Working Professionals, Parents

Difficulty is subjective and depends on your strengths, test-taking style, and familiarity with technology.

TOEFL is considered more predictable and structured, making it ideal for students who prefer clear, academic tasks. The test uses advanced vocabulary and focuses on university-level content, which can be challenging but is also easier to prepare for with consistent practice. For many test-takers, TOEFL is better than Duolingo when it comes to academic recognition and comprehensive preparation resources. Students planning to study in the United States should consider starting with a TOEFL practice test to evaluate their readiness and identify areas for improvement.

PTE appeals to tech-savvy individuals comfortable with computer interfaces. The fully automated format means you never interact with a human examiner, which some find less stressful. However, the variety of question types requires thorough familiarization.

IELTS strikes a balance between academic and conversational English. The face-to-face Speaking interview is often seen as more natural, particularly for those who feel anxious speaking into a microphone. IELTS is suitable for a wide range of test-takers, from college students to working professionals.

Duolingo’s adaptive format can feel unpredictable, as questions change difficulty in real time. The short duration and convenience make it attractive, but the lack of structured sections can be disorienting for those used to traditional test formats. Duolingo rewards authentic communication skills and is ideal for confident speakers who can think on their feet. However, for students targeting top universities or requiring comprehensive academic English assessment, TOEFL preparation may provide more robust training.

For college students, TOEFL or IELTS offer the most comprehensive assessment and widest acceptance. Working professionals who need results quickly may prefer PTE or Duolingo. Parents supporting their children should consider the university’s preferences and the student’s test-taking style when making a recommendation.

Speaking and Writing Evaluation: Human vs AI Scoring, Proctoring and Security

The evaluation method impacts how your performance is assessed and the consistency of scoring.

TOEFL uses a combination of human raters and AI scoring for the Speaking and Writing sections. This hybrid approach aims to balance objectivity with nuanced judgment. All TOEFL tests are strictly proctored, whether at a test center or through the Home Edition with live remote monitoring.

PTE relies entirely on automated scoring, with AI algorithms evaluating all responses. This ensures consistency and eliminates human bias, though some test-takers feel uncomfortable with the lack of human evaluation. PTE’s computer-based format includes robust security measures and identity verification.

IELTS employs human examiners for the Speaking section, conducted as a one-on-one interview, and the Writing section is evaluated by certified raters. Some test centers use double-marking for Writing to ensure fairness. This human touch appeals to those who value personal interaction and contextual understanding.

Duolingo uses AI to score all sections, including Speaking and Writing. The test is proctored through continuous video and screen recording, which is later reviewed by human monitors to ensure test integrity. While the AI scoring is fast and consistent, the adaptive nature and reliance on algorithms mean that responses must be clear and direct to receive accurate evaluation.

Visa, Immigration, and PR Use Cases: USA (F-1/OPT), Canada (SDS/Express Entry), UK, Australia

Different countries and visa categories have specific test requirements, so alignment is crucial.

For US student visas like the F-1, TOEFL is the most commonly accepted and trusted test. Duolingo is also widely accepted for admission purposes, though TOEFL tends to be preferred by immigration authorities and employers for OPT and work authorization. IELTS is accepted but less dominant.

Canada’s Express Entry system for permanent residency and the Student Direct Stream accept IELTS, CELPIP, and in some cases, PTE. TOEFL and Duolingo are accepted by universities but not always for immigration pathways, so verification is essential.

In the United Kingdom, IELTS is required for most visa categories, including student and work visas. IELTS for UKVI is a specific version mandated for visa applications. PTE is also accepted for UK visas. TOEFL and Duolingo are less commonly used for immigration purposes in the UK.

Australia requires IELTS or PTE for student visas and skilled migration programs. PTE is particularly popular due to its rapid results and full acceptance by the Department of Home Affairs. TOEFL is accepted by universities but is less common for visa purposes. Duolingo is not widely accepted for Australian immigration as of now.

Always consult the official immigration website of your destination country to confirm test acceptability for visa and permanent residency applications.

Preparation Strategy and Official Practice Resources: Sample Questions, Mock Tests, Tips

Strategic preparation is the key to achieving your target score, regardless of which test you choose.

For TOEFL, structured preparation is essential. Official resources from ETS include sample questions, full-length practice tests, and guided courses. Taking a TOEFL mock test early in your preparation helps you understand the format and set a baseline score. For comprehensive guidance, consider enrolling in TOEFL test preparation programs that offer personalized feedback, video lessons, and timed practice. Developing strong note-taking skills and mastering academic vocabulary are critical for success.

PTE preparation should focus on familiarizing yourself with the computer interface and varied question types. Official Pearson practice software and scored mock tests provide realistic simulation. Practicing typing speed and accuracy is important, as the test is entirely computer-based.

IELTS preparation benefits from using Cambridge IELTS books, official sample papers, and practice tests. The British Council and IDP offer online resources and preparation courses. Practicing the face-to-face Speaking interview format with a partner or tutor can build confidence.

For Duolingo, adaptive practice is key. The official Duolingo English Test website offers sample questions and free practice tests. Since the test is shorter and more spontaneous, focus on improving real-time communication skills, speaking naturally without over-preparing scripted responses, and practicing under timed conditions. The adaptive nature means you cannot predict exactly which questions will appear, so broad language proficiency is more valuable than memorized templates.

Whichever test you choose, consistent practice, realistic mock tests, and targeted improvement of weak areas will maximize your chances of success.
