A Rasch Model for Partial Credit Scoring
Psychometrika, 1982A unidimensional latent trait model for responses scored in two or more ordered categories is developed. This “Partial Credit” model is a member of the family of latent trait models which share the property of parameter separability and so permit “specifically objective” comparisons of persons and items.

Extensions of the Partial Credit Model
Psychometrika, 1989The partial credit model, developed by Masters (1982), is a unidimensional latent trait model for responses scored in two or more ordered categories. In the present paper some extensions of the model are presented. First, a marginal maximum likelihood estimation procedure is developed which allows for incomplete data and linear restrictions on both the

For some measuring instruments, item responses may reflect a degree of correctness (or a degree of appropriateness in the case of survey questionnaires) in the answer to a question, rather than being simply classified as correct/incorrect.

The Partial Credit Model (PCM) is a unidimensional model for the analysis of responses recorded in two or more ordered categories. In this sense, the model is designed for the same purpose as several other models in this book, including Samejima’s graded response model (Samejima, 1969).

A Steps Model to Analyze Partial Credit
1997The partial credit model (PCM) by Masters (1982, this volume) is a unidimensional item response model for analyzing responses scored in two or more ordered categories. The model has some very desirable properties: it is an exponential family, so minimal sufficient statistics for both the item and person parameters exist, and it allows conditional ...

The Partial Credit Model and Null Categories
Psychometrika, 1993A category where the frequency of responses is zero, either for sampling or structural reasons, will be called a null category. One approach for ordered polytomous item response models is to downcode the categories (i.e., reduce the score of each category above the null category by one), thus altering the relationship between the substantive framework ...
