What I find interesting is that so many schools don't meet the KPIs and metrics anyway despite stripping away most of the educational experience that isn't test prep.

If that was yielding great test scores it would be one thing, but even that isn't happening in many states (or any state that I've looked at but I only pay attention to a few).

The tests are made to fit a distribution. But test prep is so demotivating and inhumane, much less people are able to cope with it.
