Background of Study: Two-tier items compensate the limitation of simple multiple choice items that cannot measure the reason of selection of the alternatives. Three-tier items compensate the limitation of two-tier items that cannot measure the certainty of the responses. It is not common to use three-tier tests in the literature and there are validity and reliability problems with three-tier tests.
