Like it or not, it is NECESSARY to determine whether the taught material has been learned. There is no other way than some sort of TEST, and given the millions of subjects (students) who must be evaluated, there is no alternative to STANDARDIZED TESTS.
Teachers complain about basically everything, but their complaints about standardized tests are that they take too much time, they are used inappropriately, some teachers "teach to the tests," and they often disagree with the conclusions of the tests - which students have learned the materials best.
The same things are used as complaints about performance reviews in the Real World. Those complaints do not compel a conclusion that standardized tests be eliminated, but merely that they be modified to be better. I have never heard even a hint that the AFT or the NEA has volunteered their collective mountains of experience and knowledge to improve, for example, the SAT or the ACT. They would rather complain and fight against any proposal that teachers be evaluated on how much their students have learned.
Yet another illustration of why teachers aren't professionals, and their unions are nothing more than labor unions with nicer clothes.
