Existing cognitive diagnosis models (CDMs) assume dichotomous attributes and dichotomous responses. In this study we developed new CDMs for polytomous attributes and polytomous responses. A higher-order structure was imposed on the polytomous attributes. A brief simulation demonstrated a acceptable parameter recovery by using the Bayesian methods for parameter estimation.
