> race here is an an unwitting proxy to income, so disaggregate by household per capita income

Poor white students do better academically than well off black students. So splitting by race is more informative when discussing academic performance.

Do you have some evidence to back that up? There are some dumb rich people, no doubt of every color, however there is a clear correlation between income and performance in every reputable source I’ve ever seen.

I find it hard to believe that on average rich black kids are doing worse than on average poor white kids.

Here's a study[1] that breaks down SAT scores by race and income in 2003. Take a look at table 2.

I believe that study shows that the affect of race on SAT scores when a more complex model of income and parental education is taken into account is halved (i.e., the observed 100 pt difference drops to 50). So I think it still doesn't excuse the original post from taking income into account.

Yes, a multifaceted approach that takes into account lots of factors would be ideal. It’s still better than existing rankings though, which just use a statewide average.
