| Sumario: | A program for obtaining ability estimates and their standard errors under a number of different psychometric models is described. The general models discussed are classical test theory, item factor analysis for continuous—unlimited and continuous—censored responses, and unidimensional and multidimensional item response theory graded response models. The program can be employed to complement the various programs that are available commercially and that allow item parameters to be estimated. |
