Differences between TOEFL iBT and TOEFL ITP
TOEFL is a well-known test for measuring English proficiency and is a popular test among English learners. TOEFL is divided into types such as "TOEFL iBT" and "TOEFL ITP", but many people may not understand the difference between each test.
There are many differences between TOEFL iBT and TOEFL ITP in terms of test format, score structure, test time, test fee, etc., but the most important difference is the test content. TOEFL iBT measures four English skills in reading, listening, speaking and writing. On the other hand, TOEFL ITP measures two skills of reading and listening and grammar skills.
In addition, TOEFL iBT is generally required when entering an overseas educational institution or studying abroad. When studying abroad, the TOEFL ITP results will often not be accepted as admission requirements.
In this article, I will introduce a reference book for TOEFL iBT that can measure the four skills of English.
