Ok, I take you to mean that you don't mind the test having consequences and think it's a good idea to have such a test, but you're unhappy with the quality of the test that has been made. This seems like a very reasonable position.
In high school I refused to finish a test that was required for my graduation because I was unhappy with the quality of the test. It was a state of Arkansas thing. I had to retake it, and the second time I didn't answer any questions at all, except the essays, where I wrote in detail about my problems with the test.
Maybe this was foolish of me, but luckily neither I nor anyone else ever had to take the test again, and it never counted for anything.
One of my complaints about the test was that it was obvious that more of my classmates were going to fail the math section than they could possibly hold back from graduation, and indeed, some 20% or so failed. (I got nearly a perfect score because this was before I had simply had enough of it.) More minor problems were that I had multiple copies of some questions, they were poorly worded, focused on the wrong things, and stuff like that.
In contrast, I thought the SAT was a very reasonable test. My only complaint is that too large a fraction of students get a perfect score on the math section, leaving no ability to distinguish competent students from those who really excel. I think this is done deliberately, for political reasons, specifically to discriminate against Asian and Jewish males who would otherwise make up an uncomfortably large fraction of the top scorers. Similarly, the vocabulary section gets too much weight, again to discriminate against Asians and other foreigners. But that one small issue aside, the SATs set a standard that I wish other standardized tests would imitate.
The general rule of thumb is that local and state tests tend to be worse than national tests, which suggests to me that we underutilize the economies of scale in test making.
Anyway, I wish you luck. It's hard to overstate the importance of good tests. You get what you measure. Just ask Volkswagen.
