Developing examinations that use equal raw scores for cut scores

This study describes and demonstrates a set of processes for developing new forms of examinations which are intended to have equivalent cut scores in the raw score metric. This approach goes beyond the traditional Rasch-based approach which develops forms with cut scores that are equated in the logit metric. The methods described in this study can be used to create multiple forms of an assessment, all of which have the same raw score cut score (i.e., the number correct required to pass each examination form represents the same amount of the underlying construct). This paper provides an overview of equating standards, the research related specifically to pre-equating procedures, and three guidelines which can be used to achieve equal raw score cut scores. Three examples of how to use the guidelines as part of an iterative form-development process are provided using simulated data sets.
