Given that equating/linking applications are now appearing in kinesiology literature, this article provides an overview of the different types of linked test scores: equated, concordant, and predicted. It also addresses the different types of evidence required to determine whether the scores from two different field tests (measuring the same construct) can be used interchangeably (equated). Thus, evidence issues are addressed to help the reader determine whether the creation of equipercentile equated or concordant scores is appropriate and useful. The article is organized according to the following issues: (a) the degree to which the two tests measure the same construct, (b) the equating/linking process, (c) the evaluation of equating/ linking function, and (d) stability of equating/linking function across populations.
