The assumption that examinees either know the answer to a test item or else guess at random is usually totally implausible. A different assumption is outlined, under which formula scoring is found to be clearly superior to number right scoring. (Author)

Admissible probability testing is a way of administering multiple choice tests in which a student states his subjective probability that each alternative answer is correct. His response is then scored by an admissible scoring system designed so that the student will perceive that is is in his interest to report his true subjective probability.…

Gilman and Ferry have shown that when the student's score on a multiple choice test is the total number of responses necessary to get all items correct, substantial increases in reliability can occur. In contrast, similar procedures giving partial credit on multiple choice items have resulted in relatively small gains in reliability. The analysis…

A new scoring procedure for multiple choice tests attempts to assess partial knowledge and to restrict guessing. It is a variant of Coombs' elimination scoring method, adapted for use with the carbon-shield answer sheets commonly used with answer-until-correct scoring. Examinees are directed to erase the carbon shields of choices they are certain…

This paper presents the development of scoring functions for use in conjunction with standard multiple-choice items. In addition to the usual indication of the correct alternative, the examinee is to indicate his personal probability of the correctness of his response. Both linear and quadratic polynomial scoring functions are examined for…

One formulation of confidence scoring requires the examinee to indicate as a number his personal probability of the correctness of each alternative in a multiple-choice test. For this formulation a linear transformation of the logarithm of the correct response is maximized if the examinee accurately reports his personal probability. To equate…

Compares various item option scoring methods with respect to coefficient alpha and a concurrent validity coefficient. Scoring methods compared were: formula scoring, a priori scoring, empirical scoring with an internal criterion, and two modifications of formula scoring. The empirically determined scoring system is seen as superior. (RC)

Findings regarding formats and scoring formulas for multiple-choice test items with more than one correct response are presented. Strong cluing effects in the Type K format, increasing the correct score percentage and reducing test reliability, recommend using the Type X format. Alternative scoring methods are discussed. (Author/CM)

Binary, probability, and ordinal scoring procedures for multiple-choice items were examined. In two situations, it was found that both the probability and ordinal scoring systems were more reliable than the binary scoring method. (Author/CTM)

A mathematics achievement test with instructions to avoid guessing wildly was given to 168 elementary school pupils who were later asked to complete all the questions using a differently colored pencil. Results showed examinees, particularly the more able students, tend to omit too many items. (CTM)

The present study was an attempt to alleviate some of the difficulties inherent in multiple-choice items by having examinees respond to multiple-choice items in a probabilistic manner. Using this format, examinees are able to respond to each alternative and to provide indications of any partial knowledge they may possess concerning the item. The…

An examinee is required to express his confidence in the correctness of each choice of a multiple-choice item in a probabilistic test. For the responses to be valid indicators the confidence expressed in each choice should be determined by an examinees' knowledge. This study assessed the relationship of the certainty of examinees' responses to…

The effects of luck and misinformation on ability of multiple-choice test scores to estimate examinee ability were investigated. Two measures of examinee ability were defined. Misinformation was shown to have little effect on ability of raw scores and a substantial effect on ability of corrected-for-guessing scores to estimate examinee ability.…
