The robustness of number - right, one- , two- and three - parameter item - response, finitestate, and partial - credit scoring was examined with respect to the violation of the equally classifiable options and option independence made in finite - state scoring. All other assumptions underlying the use of these scoring models were met for each of four subtests that varied in terms of the violations. Analysis of the responses of 1,232 high school seniors on the subtests revealed that the number right and one-, two- and three- parameter scoring methods were equally sensitive to the presence of best answers (lack of option independence) and that the number - right and one- and two- parameter methods were equally sensitive to the presence of absurd option and stem - option conncetions (unequal classification of options) and pairs of similar or opposite options (lack of option independence, unequal classification of options). The three - parameter model and the finite - state scoring models adversely sensitive to the presence of testwiseness.
