NAV TEST ITEM 11.12.20
An item is the basic unit of interaction on a test. What we often call a test question is more properly known as an item, since it may not be worded as an actual question. The student's feedback is also more properly known as a response rather than an answer, but we won't get too particular on that point. Items can be written in various formats, including multiple choice, matching, true/false, short answer, and essay. We will discuss some of these formats in another article.
Since items are the actual points of interaction of students with the test, item quality is probably the most recognizable indicator of the overall quality of the test. High quality test items take time and effort to write, but are essential to a valid test. Items must test skills and knowledge of the subject at hand, not the student's test taking skills.
