| Abstract: | This study investigated using latent class analysis to set performance standards for assessments comprised of multiple-choice and performance assessment items. Employing this procedure, it is possible to use a sample of student responses to accomplish four goals: (a) determine how well a specified latent structure fits student performance data; (b) determine which latent structure best represents the relationships in the data; (c) obtain estimates of item parameters for each latent class; and (d) identify to which class within that latent structure each response pattern most likely belongs. Comparisons with the Angoff and profile rating methods revealed that the approaches agreed with each other quite well, indicating that both empirical and test-based judgmental approaches may be used for setting performance standards for student achievement. |
