The Impact of Alternative Scoring Procedures for Multiple-Choice Items on Test Reliability, Validity, and Grading.
Jaradat, Derar; Tollefson, Nona – Educational and Psychological Measurement, 1988
This study compared the reliability and validity indexes of randomly parallel tests administered under inclusion, exclusion, and correction for guessing directions, using 54 graduate students. It also compared the criterion-referenced grading decisions based on the different scoring methods. (TJH)

Determining the Length of Multiple Choice Criterion-Referenced Tests When an Answer-Until-Correct Scoring Procedure Is Used.
Wilcox, Rand R. – Educational and Psychological Measurement, 1982
When determining criterion-referenced test length, problems of guessing are shown to be more serious than expected. A new method of scoring is presented that corrects for guessing without assuming that guessing is random. Empirical investigations of the procedure are examined. Test length can be substantially reduced. (Author/CM)
