Validity of Specific Purpose Language Tests

A specific purpose language test is one in which test content and methods are derived from an analysis of a specific purpose target language use situation, so that test tasks and content are authentically representative of tasks in the target situation […]. Such a test allows us to make inferences about a test taker's capacity to use language in the specific purpose domain (Douglas, 2000: 19).
