Language Testing Terminology
1. Validity: The test accurately reflects the content of the syllabus on which it is based, and in suitable proportion. It tests nothing else!
2. Reliability: a reliable test should be a consistent measure of performance. Hypothetically, the score obtained by a student should be very similar to what would have been attained on a different occasion.
3. OPI; This stands for Oral Proficiency Interview, the speaking test component of STANAG proficiency tests.
4. Level Check: In an OPI test, this is when a tester checks to see if the student is at the level they expect them to be. It confirms the assumed ability of the student.
