News media reports about Scholastic Aptitude Test (SAT) scores and trends have drawn or suggested conclusions about the quality of schools, teachers, and colleges that are neither supported by evidence from the test itself nor consistent with its nature and purpose. (MSE)

The effectiveness of a model for determining a minimal cut-off score for criterion-referenced tests was examined. The model, based upon techniques presented originally by Nedelsky and by Angoff, was first used in conjunction with a multiple choice test developed for use in certifying school counselors in Georgia. A "knowledge estimation panel" was…
