Your discussion regarding this would be of help to all of us. I am glad for the book's publication, because it raises some very important issues. Many schools do rely heavily on standardized tests, although in my experience working with over a dozen institutions, most prefer to use information from a students high school academic record as a far better measure of a students likely college performance. In reality, many schools attempt to evaluate thousands of students in a relatively short period of time.
Scores are the only objective measurement that can be used in that system.
Grade, rank in class, extracurricular activities, essays and recommendations are all subject to whims and vagaries, whether by schools, counselors or the individuals students. Scores, when used as in conjunction with these factors, give us a powerful tool, but clearly an inadequate one. Every school loses students, which is difficult for students and financially damaging to schools. I will continue to advocate the use of any measurements that assist us in that pursuit. Unfortunately, there is no possible way we can ever truly know who will meet these criterion.
