The Many Facer Rasch Measurement model (Linacre, 1989) is a Rasch model which allows us to estimate parameters not only for person's "ability" in a item and the item "difficulty", but also for other aspects (facets) that are believed to be relevant to the research goals. Because of its peculia~ities,this model is especially indicated for benchmarking. It combines the properties of every Rasch model with the flexibility of use and the ease in considering different dimensions which share the same latent trait. In this article, the model features in relation to benchmarking are discussed, and benchmarking is ap- plied to hospitals and departments as regards patients' satisfaction.

Abstract
The Many Facer Rasch Measurement model (Linacre, 1989) is a Rasch model which allows us to estimate parameters not only for person's "ability" in a item and the item "difficulty", but also for other aspects (facets) that are believed to be relevant to the research goals. Because of its peculia~ities,this model is especially indicated for benchmarking. It combines the properties of every Rasch model with the flexibility of use and the ease in considering different dimensions which share the same latent trait. In this article, the model features in relation to benchmarking are discussed, and benchmarking is ap- plied to hospitals and departments as regards patients' satisfaction.Pubblicazioni consigliate
