Study was designed to provide some indication as to whether the gain in test reliability from confidence scoring results from relevant or irrelevant sources. If the increase in reliability is the result of a gambling response style, it is conceivable that validity could actually decrease even though reliability is increased. (Authors/CB)

Effects of logically weighting incorrect item options in conventional tests and different scoring functions with confidence tests on reliability and validity were examined. Ninth graders took conventionally administered Verbal and Mathematical Reasoning tests, scored conventionally and by a procedure assigning degree-of-correctness weights to…

Various aspects of Confidence Weighting are examined. Variant of Confidence Weighting, its effect on test reliability, and the validity of Confidence Weighting are discussed. (DG)

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)
