Summarizing item-level properties
A typical educational test consists of a large number of multiple-choice items. In the construction and pretesting of a test form, particular attention is paid to every item of the form. Each item is screened for a number of possible faults, such as non-existence or non-uniqueness of the correct answer among the response options, use of words or expressions that may have a different connotation or may be more (or less) familiar to an ethnic category of examinees, may require non-elementary knowledge from a different subject area, and the like.
