So having read the article near as I can tell schools are 'scored' based upon their students test scores. Schools with predominately asian students do well, schools with predominately black students don't, and whites and hispanics fill the middle.
The school system has decided to change how those scores are calculated based upon the race of the students. So that now all those schools that were lower performing can use the lower standards for the black students to bring up their scores.
In one sense I could almost see schools competing for black enrollment so that their score goes up, but that is about the only positive thing about this law. And not likely to happen.
The reality is that instead of using those metrics to identify schools that are failing their students and local community, so that funding or corrective action can be taken, the system has decided to skew the numbers to bury the problem. I'm pretty sure based upon recent events it's clear that skewing numbers to make things look better leads to a lot of wishful thinking but nothing concrete. To actually address the problems is harder work, and potentially more embarassing to the administrators than it is to blame the kids. Never mind how incredibly ignorant and insulting their approach is.
Again, it's about the administrators, not about the kids.
