What would be a better way to measure performance?  (It's a sincere question and one that I've long been wondering about). Or is there even a cost effective measure?<p>I realize that many teachers unions are against standardized testing and any form of performance testing in general, but what's the alternative?<p>Could the problem instead be how the tests are structured or how cheating gets controlled?  I note that at least with respect to SAT's the SAT is only one measure, albeit a significant high stakes benchmark that can change a student's life depending on their admissions.  Given limited spots and limited resources, how else should universities be choosing who gets in?
