The TOEFL exam tests your proficiency in English. However, there are several ways to take the test. The TOEFL Internet Based Test (iBT) was introduced in late 2005 and has revolutionized the English proficiency exam. The Computer Based Test (CBT) was then discontinued in September 2006, consequently making all CBT test scores invalid. In 2011, the TOEFL iBT is the most popular version taken. However, many countries still offer the Paper Based Test (PBT) TOEFL. Interestingly, Singapore only offers the iBT. Below, we’ll explore the key differences between the iBT and the PBT.
Format – Sorry to state the obvious, but the iBT is conducted using a computer via the internet. You are also given a headset to record speaking answers. The PBT simply uses everyday paper booklets.
Speaking – During the iBT, there is a speaking section. You are given a series of tasks that involve you speaking out loud to the computer. In the TOEFL iBT exam, you are required to record your answer into a microphone. The computer will save your vocal response and examiners will then listen to you and grade you accordingly. The PBT TOEFL has no speaking section.
Integrated tasks – These tasks only exist on the iBT TOEFL. An integrated task requires you to use multiple skill sets to answer questions. For example, during the iBT writing section, you are given a passage to read about a topic, then you will listen to a lecture related to the reading passage. Your task is then to write an essay about what you just heard and read.
Timing – The biggest difference between the two exams is the exam length. In total, the PBT takes three and a half hours to complete whereas the iBT takes four and a half hours!
Ultimately, my suggestion is to take the iBT, as it produces a more accurate representation of your English language capabilities. Furthermore, universities tend to prefer iBT marks over PTB scores.
