There are several types of objective items that can be used to test students' knowledge: matching tests, multiple choice tests, true/false tests, correct/incorrect tests, simple recall tests, best answer tests, completion tests, and classification tests. When constructing a test, teachers should identify the test objectives, decide which item types to use, prepare a table of specifications to ensure a balance of item difficulties, construct draft items, and perform an item analysis after a try-out with students. Essay items can also be used to test higher-order thinking and come in long response or limited response formats.
