Three methods are described for empirically assessing utility functions: (1) a method for scaling utility mixtures, consisting of a true achievement or criterion level combined with the probability of passing the test or being accepted, which is applicable for determining optimal decision procedures; (2) a method for scaling the utility as a function of the true achievement or criterion level; and (3) a graphical procedure for choosing a utility function. These methods are useful for investigating the utility structure. The three methods are investigated using 30 students in a hypothetical educational Pass/Fail situation and appear to yield reliable information. Moreover, an overview of the students’ utility structures is reported.enArticle
