Abstract
Two procedures, one based on item difficulties, the
other based on person abilities, were used to equate 14
forms of a reading comprehension test using the Rasch
model. These forms had no items in common. For
practical purposes, the two procedures produced
equivalent results. An advantage of common-person
equating for testing the unidimensionality assumption
is pointed out, and the need for caution in interpreting
tests of common-item invariance is stressed.
