TOEFL, IELTS, and Duolingo. Which test is the right one for you? Deciding which English test to take can be a major hurdle for international students. Each test is a valuable credential, but the best choice depends on your university goals, budget, and testing style.
At ISAL, we pride ourselves on a rigorous curriculum that prepares students for the specific demands of these exams. Our goal is to ensure you get exactly what you pay for: total English mastery and the high scores needed for your next step in life.
English proficiency tests are the “gatekeepers” for international education, employment, and visa requirements. These standardized benchmarks ensure you can thrive in fast-paced, English-speaking environments without the stress of language barriers.
Choosing the right test is a strategic decision that saves you both time and money. With the major TOEFL redesign on January 21, 2026, and the rise of the Duolingo English Test, the landscape has changed. Acceptance rates, pricing, and result wait times vary significantly between exams. At ISAL, we guide you through this complexity with test-specific strategies that steer you toward success.
The TOEFL exam (Test of English as a Foreign Language) is the gold standard for students applying to academic programs in the U.S. and Canada. Effective January 21, 2026, the TOEFL iBT has been completely overhauled to be faster and more adaptive.
Format: The test is now a streamlined 90-minute adaptive exam. The Reading and Listening sections adapt in difficulty based on your performance.
Scoring: Transitioning to a 1.0–6.0 band scale (aligned with CEFR), though you will still receive a comparable 0–120 score during the two-year transition period.
Content: A mix of academic lectures and “Read in Daily Life” tasks like campus emails and simulated interviews.
Cost: Typically $250, with results delivered within 72 hours.
Because of its new adaptive nature, a TOEFL practice test is more important than ever to master the pacing. ISAL’s preparation courses are updated to match these 2026 standards exactly.
The IELTS exam (International English Language Testing System) is globally recognized and often preferred by universities in the UK, Australia, and New Zealand, as well as many US institutions.
IELTS Academic: Designed for students pursuing higher education. It features a face-to-face speaking section with a human examiner, which many students find more natural than speaking to a computer.
IELTS General Training: Used primarily for work or migration purposes (such as the Canada Express Entry or UK work visas).
Scoring & Cost: Scored on a 0–9 band scale. The test takes approximately 2 hours and 45 minutes and costs between $280–$340.
ISAL provides expert-led IELTS practice test sessions, specifically focusing on the “One Skill Retake” strategy and human-centered communication.
The Duolingo English Test (DET) is the modern, “at-home” alternative that has gained massive popularity for its speed and affordability.
Convenience: A fully online, adaptive test you can take from your own room in under one hour.
Fast Results: Standard results arrive in 48 hours, but you can pay for 12-hour rush scoring.
Cost: Only $70, making it the most budget-friendly option.
Acceptance: Now accepted by over 5,000 institutions worldwide, particularly in the US.
Success on this test requires a unique set of skills, such as “Interactive Listening.” ISAL’s Duolingo English practice test resources help you master these non-traditional question types.

The best test is the one that aligns with your strengths and your target school’s requirements:
Choose the TOEFL exam if you are academically focused, prefer a shorter, high-tech adaptive test, and are targeting elite U.S. universities.
Choose the IELTS test if you prefer speaking to a person, need a “One Skill Retake” option, or are applying for visas in the UK, Canada, or Australia.
Choose the Duolingo English Test if you need results immediately, are on a budget, and your school accepts it.
