In 2005, the College Board added a required writing section to the SAT, and ACT added an optional writing test to the ACT. Before 2005, ACT and the College Board had periodically produced concordance tables to assist admission officers who wanted to understand how students of comparable ability would score on the two college entrance examinations. Given the changes to both tests, the College Board and ACT are now providing updated concordance tables that are based on the current versions of the two tests.
In recent years, conflicting reports have circulated about the number of colleges and universities that have made standardized tests optional, rather than required, for admission. The National Center for Fair and Open Testing, or FairTest, has widely publicized a list of 391 colleges and universities that, it claims, do not require admissions tests for admitting substantial numbers of students into bachelor degree programs. In this study, the number of such institutions are reanalyzed by examining colleges and universities that have SAT or ACT optional policies for making admissions decisions. Additionally, the characteristics of institutions on the FairTest list--including the type of institutions and the competitiveness of their admissions policies--are compared with all four-year U.S. colleges.
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 composite scores.
Correspondences between ACT and SAT I scores are presented from a conceptual framework that distinguishes among three kinds of correspondences: equating, scaling, and prediction. Relationships among the different scales of the ACT and SAT I are described in the context of the conceptual framework. Sums of scores, composites of scores, and individual scores are examined.
This paper describes how results on the ACT and SAT I can be compared through statistical linking procedures.
Marco and Abdel-fattah (1991) reported newly established relationships between scores on the enhanced American College Testing Program (ACT) Assessment and scores on the SAT. Fourteen large universities provided data on applicants who had taken both the enhanced ACT Assessment and the SAT. The report provides a detailed description of the methodology used to develop the ""concordance"" tables reported in the 1991 study, as well as the methods used to establish comparability between scores on the ACT Composite from the enhanced ACT Assessment and scores on the SAT-V and SAT-M composite (SAT-V + M). The results should aid test users in attempting to compare the performance of students taking these different tests.
