Abstract:

Three computer programs are described for scoring test response data using item characteristic curve ICC or latent trait models. The rationale and mathematical basis of both maximum likelihood and Bayesian ICC scoring methods are presented, as well as some data comparing the two methods of scoring. The three computer programs are designed for scoring conventional linear test data LINDSCO in dichotomous response format, adaptive test dichotomous data ADADSCO, and conventional linear test data scored by polychotomous ICC models LINPSCO. Options available in these three general purpose programs are described, and examples of the input and output are given for each program. Complete FORTRAN listings of the three programs are included.
