An approach to analyzing items is described that
emphasizes the heterogeneous nature of many achievement
and professional certification tests. The approach
focuses on the categories of a table of specifications,
which often serves as a blueprint for constructing such
tests. The approach is characterized by profile comparisons
of observed and expected correlations of item
scores with category scores. A multivariate generalizability
theory model provides the foundation for the approach,
and the concept of a profile of expected correlations
is derived from the model. Data from a
professional certification testing program are used for
illustration and an attempt is made to provide links
with test development issues and generalizability theory.
