Communicative language testing is intended to provide the tester with information about the
testee’s ability to perform in the target language in certain context-specific tasks. It has to be
recognised that given the constraints of time and practicality, only a small sample of the testee’s
language can be collected, and that however realistic the tasks may be intended to be, the testee’s
performance will inevitably reflect the fact that s/he was performing under test conditions.
