The purpose of this study was to describe a procedure
based on generalizability theory for assessing the
adequacy of item groupings generated by means of a
domain-referenced testing system. The procedure is
based on an exploration of the extent to which items
are grouped into homogeneous sets with similar levels
of difficulty, when the sets are defined on the basis of
a logical analysis of the perceived skills underlying the
items. In addition, an example of the use of the developed
analytic procedure is presented.
