Both TOEFL and IELTS are widely accepted by US MBA programs for admissions, and neither is inherently better than the other. The choice between the two often depends on individual preferences and strengths.
In terms of ease and preparation time, opinions may vary from person to person. TOEFL generally focuses on American English and is entirely computer-based, including a speaking section where you interact with a computer. IELTS, on the other hand, is a paper-based test and might be perceived as more natural by some test-takers as it involves face-to-face speaking with an examiner. The best choice depends on your personal learning style and comfort with the test format.
When it comes to return on investment (ROI), both tests hold equal weight in the eyes of most MBA programs. Admissions offices are typically looking for a certain level of proficiency in English, and both TOEFL and IELTS are designed to assess language skills at a high academic level.
As for school preferences, many MBA programs don't have a strict preference for one test over the other. However, it's essential to check the specific requirements of each school you're applying to, as some may have a preference or may accept one test over the other.
Ultimately, the decision between TOEFL and IELTS should be based on your personal strengths, preferences, and the specific requirements of the MBA programs you are interested in. It's advisable to assess the format of each test, consider your comfort level, and choose the one that aligns best with your abilities and preferences.
