The Scholastic Aptitude Test (SAT), the most widely publicized test taken by Americans, strongly influences public opinion about the quality of American schools. Unfortunately, the SAT scores not only have no statistical validity for tracking trends in the achievement of American students but actually show a perverse relationship to the trends in achievement as tracked by statistically valid scores. Thus the scores are quite misleading indicators of the quality of schools. The College Entrance Examination Board, a nonprofit institution established to foster excellence in education, clearly understands the statistical limitations of the SAT scores yet actively seeks annual publicity around the release of national, state, and school district SAT scores. This article questions whether the decision by the College Board to continue publishing aggregate SAT scores is in the public interest.The Scholastic Aptitude Test (now called the Scholastic Assessment Test; SAT) occupies a unique place in our national consciousness. It is probably the most widely taken "high-stakes" test in the nation. It has been taken over the past 40 years by most students interested in applying for college admission-over one third of high school graduates. The score received has partially determined whether college admission is granted and which college one attends. Like many other high-stakes tests, the SAT has attracted criticism from many quarters. These criticisms focus on whether the test is equitable to all those taking it, whether it can validly predict success in college, and whether its use improves the college admission process (Grouse & Trusheim, 1983;Jacobs, 1995). All of these concerns focus on the appropriate interpretation and use of individual-level scores in the college admission process. Similar to other tests that are influential in critical decisions, remedies for issues concerned with test validity or perceived inequity are sought through the courts.There is a unique issue in public policy associated with the publication and use of aggregate SAT test scores. The publication of aggregate score averages for schools, school districts, states, and the nation need not be done to carry out the primary purpose of the test: the sorting of individuals in the college admission process. However, annual SAT average scores have been routinely published at all levels since the 1960s. These scores receive widespread media coverage at every level because they provide easy and, in many cases, the only available comparative score data among local schools and school districts and among states. Because SAT scores are given at the end of K-12 education, they are often seen as providing indicators of the quality of the K-12 education system.
