So what value is this fancy test actually supposed to produce, once you have it?
Comparison between schools, for starters. As an information for parents where to put their kids.
Today, there are many schools that inflate grades, because people use “good grades” as a proxy for “more knowledge”. Which would be closer to the truth if we had better tests, but today it is too easy to cheat.
In absence of objective testing, the competition between schools is mostly about marketing. This is how you get schools that spend a lot of money on sports and various shiny toys, but provide mediocre education.
I have taught in different schools, so I know from personal experience that there is a huge difference between how much education the kids get in different schools. But even if a parent trying to get the best education for their child asks me, it is almost impossible for me to prove any of this; there is nothing legible to point at, other than say “trust me, that school is utterly dysfunctional, but they give every student good grades, and they have an army of lawyers to threaten any teacher who talks about what happens there, and the director is a charming psychopath who can convince most parents in a 1:1 talk that this is the best school ever, so the parents are happy to give him lots of money believing that they sacrifice for the good of their children”. (Yes, I have a specific school in mind. Not in USA.)
