Abstract
We explain why invariant item ordering (IIO) is an important property in non-cognitive measurement and we discuss that IIO cannot be easily generalized from dichotomous data to polytomous data, as some authors seem to suggest. Methods are discussed to investigate IIO for polytomous items and an empirical example shows how these methods can be used in practice.
