Distinctions were made between three classes of statistical linkage: equivalence, concordance, and prediction. These distinctions were based on rational content considerations and empirical statistical relationships. A large database involving SAT I and ACT scores was used to determine which type of linkage was best suited for different scores and…

This paper describes how results on the ACT and SAT I can be compared through statistical linking procedures.

Correspondences between ACT[superscript TM] and SAT[superscript R] I scores are presented from a conceptual framework that distinguishes among three kinds of correspondences, namely, equating, scaling, and prediction. Construct similarity plays an important role in determining the nature and degree of correspondence that can be achieved. This…

The SAT® I: Reasoning Test is administered seven times a year. Primarily for security purposes, several different test forms are given at each administration.
