An attempt is made to explore the use of subjective probabilities in the analysis of item data, especially criterion-referenced item data. Two assumptions are implicit: (1) one wants to obtain a maximum amount of information with respect to an item using a minimum number of subjects; and (2) once the item is validated, it may well be administered…

The problems stated at the outset were: to discover whether information provided by confidence testing would result in a more accurate assessment of student knowledge so more personal individualized instruction could be presented, and whether sufficient precise data could be attained to be of significant aid in curriculum planning. Analysis has…

The first four chapters of this report primarily provide an extensive, critical review of the literature with regard to selected aspects of the criterion-referenced and mastery testing fields. Major topics treated include: (a) definitions, distinctions, and background, (b) the relevance of classical test theory, (c) validity and procedures for…

This brief review explains some alternate scoring procedures to the classical method of summing correct responses. The novel procedures attempt in some way to retrieve and use even the information in the wrong responses. (Author)

Technical improvements, which may be made in the reliability and validity of tests through confidence scores, are discussed. However, studies indicate that subjects do not handle their confidence uniformly. (MS)
