Psychometrics

Making scores from different test forms interchangeable

In psychometrics, equating is the statistical process of adjusting scores from two or more forms of a test that are built to the same specifications but differ slightly in difficulty, so that a given scaled score means the same thing no matter which form a person took. It is a strict special case of the broader scaling-and-linking family, requiring that the forms measure the same construct with near-equal reliability, and it is carried out through designs such as common-item or equivalent-groups equating. Kolen and Brennan's Test equating, scaling, and linking is the standard treatment of these methods. The referent is a mapping between the score scales of alternate forms that makes their scores interchangeable.[1]
