The TOEFL iBT (Internet-Based Test) is the most widely accepted and current version of the test, taken online either at a test center or from home. It assesses four academic English skills: Reading, Listening, Speaking, and Writing. The exam lasts approximately 2 hours and is designed to simulate real university-level tasks. Scores are reported on a scale of 0 to 120, with most top universities requiring a minimum score between 80 and 100+ depending on the program.

TOEFL Essentials is a newer, shorter test (about 1.5 hours) that evaluates both everyday and academic English skills. It includes Reading, Listening, Speaking, and Writing sections but with a more engaging and adaptive format. Scores range from 1.0 to 12.0 for each section. While not accepted by all universities, many institutions recognize it as a valid and flexible alternative for admissions, especially for less academically intensive programs.
