The TOEFL is a unique test (which is internet based) because it tests independent skills and integrated skills. Broadly, the test examines the students’ proficiency in Reading, Writing, Listening and Speaking, typically based on a North American format.
A word on integrated skills:- Unlike certain tests like the TOEFL in which the Reading, Writing, Listening and Speaking are in depended (which means the module does not overlap), the TOEFL tests integrated skills which means that the modules could overlap. For example, in the speaking module, students may have to listen to a lecture, read a passage and then express their views.
As we can see, speaking is not just speaking alone but includes listening and reading. As the name suggests, the TOEFL measures language abilities of students, whose first language is not English The purpose of the test is to evaluate how well an individual can understand standard American English at college level for admission to many U.S College academic programs, the TOEFL is compulsory. The TOEFL is administered by ETS (Educational testing Service).
