- If the key has several choices it is described as " polychotomous " or " polytomous ".
- Andrich ( 1978, 2005 ) shows that the polytomous Rasch model requires that these dichotomous responses conform with a latent Guttman response subspace:

- In the polytomous Rasch model, a score of " x " on a given item implies that an individual has simultaneously surpassed " x " thresholds below a certain region on the continuum, and failed to surpass the remaining " m " & minus; " x " thresholds above that region.
