Results of 96 theoretical/empirical studies were reviewed to see if they support a taxonomy of 43 rules for writing multiple-choice test items. The taxonomy is the result of an analysis of 46 textbooks dealing with multiple-choice item writing. For nearly half of the rules, no research was found. (SLD)

A taxonomy of 43 rules for writing multiple-choice test items is presented, based on a consensus of 46 textbooks. These guidelines are presented as complete and authoritative, with solid consensus apparent for 33 of the rules. Four rules lack consensus, and 5 rules were cited fewer than 10 times. (SLD)

The criterion-related validity evidence and other psychometric characteristics of multiple-choice and multiple true-false (MTF) items in medical specialty certification examinations were compared using results from 21,346 candidates. Advantages of MTF items and implications for test construction are discussed. (SLD)
