English learners can choose between three popular options depending on their needs.
Test of English as a Foreign Language (TOEFL)
TOEFL has an academic feel and requires test-takers to be comfortable using a computer and speaking into a microphone to complete the speaking portion of the exam. There is no pass or fail scores — candidates are scored on a sliding scale from 0-120 points. If you’ve had more experience with American English and need an English certificate for the United States, TOEFL is probably the best option for you. TOEFL is valid for two years.
International English Language Testing System (IETLS)
With a test time of 2 hours and 45 minutes, IELTS is the shortest of the English exams. Test takers are graded on a point system from 4 to 9.9. Unlike TOEFL, IELTS has more of a real-world feel, and candidates complete the speaking portion with an actual examiner. If you’ve studied British English and plan to live in the United Kingdom, you may prefer to take IELTS. IELTS is valid for two years.
Cambridge English Qualifications
Cambridge offers a more comprehensive certification than IELTS and TOEFL, which is reflected in its longer test times. Unlike TOEFL and IELTS, it’s possible to fail a Cambridge exam, in which case you will not receive a certification. If you need an English language certificate for your resume but not for visa/work/university purposes, Cambridge is probably your best choice. Cambridge exams never expire and are accepted around the world.
