Greetings, I noticed that Mplus now provides the IRT parameterization for the partial credit model, as well as for binary responses. Is it yet possible to obtain the IRT parameterization for ordinal (categorical) responses with more than 2 categories (i.e., the graded response model)? Thank you, Lesa

No, but you can do it via Model Constraint. And, the Mplus parameterization seems to become popular - at least with more than one factor.
