This paper is about a court case decided by the U. S. Supreme Court in 1971. Although attorneys recognize that the case is important to businesses, its impact on colleges and universities has been explored by only a few. As this paper will show, "Griggs v. Duke Power" may have enormously boosted the number of students in college and may have increased the differential in income between high school and college graduates. It may have led to higher tuition, without providing commensurate additional value. This paper will describe "Griggs," the environment from which it emerged, and the subsequent judicial and political activity that created such great constraints on testing. It will discuss testing today and then provide economic information suggesting the magnitude of the changes that "Griggs" may have instigated. This paper suggests that additional scholarly work on the impact of "Griggs" on higher education is appropriate. (Contains 2 figures and 52 endnotes.)
