Colleges and universities, selective or otherwise, should continue using SAT/ACT scores in their admissions process even if it affects campus diversity. Standardized tests are not a perfect measure of a student's ability, but they offer an acceptable method of universal screening that should not be discounted. To eliminate this admissions criterion, as Wake Forest College is planning to do, would be shortsighted and would possibly create a pool of students whose knowledge base makes them ill-prepared for college level courses.
