This is where the Goverment should practice what it teaches. I understand that this data is interesting but it is utterly useless. Useless because race isn't as important as the geographical location and economic situation. Race is what you can use once you've narrowed down the demographics to the specific location and socio-economical impact, but it provides little substance without more contextual data.
If a poor neighborhood in a major city is failing math it is the a combination of the neighborhood being poor as opposed to race.
It also has specific undertones... and often people will come with a bad conclusion whether they subconsciously recognize it or not. My guess a better thing to also look at (besides what you pointed out) would be school funding. We have a problem with this in the US. Schools are going massively underfunded and we can observe a massive disparity from school to school. On the political end of this issue, there is a concerted effort to choke out school funding and to push private schools that are funded with tax dollars.
Are they underfunded though? How much is enough? Chicago for example pays probably at least 15k per student yet scores poorly. How much do they need? 20k? 50k?
Fund utility is good in addition as well. Plenty of well funded schools fail. Sometimes it is what those funds are being used for that actually drive down education.

Race is never a good demographic period.
