This investigation examined the practice of relying on field test item calibrations in advance of the operational administration of a large scale assessment for purposes of equating and scaling. Often termed “pre-equating,” the effectiveness of this method is explored for a statewide, high-stakes assessment in grades three, five, and seven for the content areas of language arts, mathematics, and social studies. Pre-equated scaling was based on item calibrations using the Rasch model from an off-grade field test event in which students tested were one grade higher than the target population. These calibrations were compared to those obtained from post-equating, which …
