An objective test is the test in which the correctness of the test taker"s response is determined wholly by predetermined criteria so that no judgment is needed on the part of scorers. (2)Language aptitude tests: An exam used to measure capacity or potential related to language acquisition as well as the use of language. (3)Diagnostic tests: A diagnostic test offers the learner the chance to use a range of language elements—they might be functions, structures, situations or vocabulary—to find out which he is familiar with and which he is not.
