Psychometricians continue to develop and evaluate methods for linking test scores, both horizontally and vertically. This article describes a social moderation process for articulating (i.e., linking) performance standards across grade levels for an operational state assessment program. The researchers used generated data to evaluate the likely classification accuracy of a Grade 2 performance standard that is intended to identify whether students are on track to achieve the proficient performance standard in Grade 3. The researchers evaluated classification accuracy for three plausible growth models and four amounts of growth; accounted for the effects of measurement error in the two tests; and illustrated the advantages of considering accurate, inaccurate, and uncertain classifications. Finally, the researchers discuss the usefulness of the social moderation process for linking performance standards in situations where overlapping test designs may not be feasible.
