Abstract
The primary purpose of this study was to
investigate the invariance properties of the Rasch
model using data from standardized achievement
tests that were not constructed to conform to the
Rasch model. The item responses of approximately
3,400 examinees (Grades 9, 10, 11, and 12) to four
separately timed sections of the Iowa Tests of
Educational Development were analyzed. The results
indicated that the Rasch model does yield reasonably
invariant item parameter and ability
parameter estimates for different tests and different
examinee groups, even though the assumptions of
the model are not met.
