Abstract
This study was concerned with the factorial validity of the Iowa Tests of Basic Skills (ITBS). Previous research identified a strong general factor for this battery, which was taken as evidence of redundancy among the subtests. Hierarchical factor analysis was done with a subset of the standardization data to explore the presence of second-order group factors. The results supported the construct validity of the Language and Mathematics subscales, though a degree of factorial complexity was found in both. Verbal and Visual Information group factors were also identified. Extension of the ITBS general and group factors to subtests of the Cognitive Abilities Test supported the interpretations made of the various group factors.
