Abstract
A reanalysis of data from Hambleton and Rovinelli (1986) argues that the methods suggested by Bejar (1980) are a valuable descriptive tool for assessing the unidimensionality assumption when a priori informa tion is available about possible response factors. Index terms: achievement testing, item response theory, uni dimensionality.Keywords
