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)

Seventeen educational measurement textbooks were reviewed to analyze current perceptions regarding true-false achievement testing. A synthesis of the rules for item writing is presented, and the purported advantages and disadvantages of the true-false format derived from those texts are reviewed. (TJH)

College students rated dissimilarity of pairs of common test item formats. A multidimensional scaling model with individual differences fit to data from 111 students suggested that they used 2 dimensions to distinguish among the formats, 1 separating supply from selection items and 1 based on the number of options.
