[quote=Anonymous]Great Schools has been useless for years. It measures metrics that are completely based on dividing schools up by race, income, and other arbitrary markers - similar to the disastrous No Child Left Behind and completely based on test scores. It then grades schools with a number calculated by the difference between the performance of different groups. So for example, a school with a completely homogeneous population where every kid does poorly will score better because there are no differences, while a school with a very diverse population where all the groups score slightly differently - but still pretty well - will score lower because there are more differences. I haven't tried to calculate the new system they are using, but it seems like now they are basing more on improvement - which is also similar to some stupid federal programs from around NCLB time - and looking only at how groups improved from last year. That usually means that a group of kids can all pass with, say, 90%, and then the school will get a low score if they don't raise that to 91% the next year. And if they get 100%, then they will be downgraded if they can't get more than 100% the following year. Anyway, that's how the federal scores worked for a while, and the whole thing is just nonsensical, which is why Great Schools is useless.[/quote]
