The TOEFL iBT is a 4.5 hour English test that tests reading comprehension, listening comprehension, speaking, and writing, all in an academic context. Because the TOEFL iBT is taken primarily by students applying for universities in the United States or other English-speaking countries, the orientation of the test is exclusively academic English.


The TOEFL iBT (Internet Based Test) was introduced in 2005 and was progressively rolled out around the world to replace the TOEFL PBT (Paper Based Test) and the TOEFL CBT (Computer Based Test). The TOEFL PBT and the TOEFL CBT have been discontinued. The scoring on these other two tests was different from the scoring on the TOEFL iBT. An at-home version of the TOEFL iBT was developed during the pandemic when in-person test centers were closed. TOEFL iBT Home Edition is identical to the test given in test centers.


The TOEFL iBT is scored from 0 to 120, with equal weight given to each of the four skills tested. Different universities require different TOEFL iBT scores, and some may also require specific scores on individual skills tested. TOEFL iBT scores are valid for 2 years after the test.
