GreatSchools is based exclusively on SOL pass rates compared to other schools in the same state. So, a GS rating of 7 in DC may not be comparable to a GS rating of 7 in VA or MD.
You can get other data by looking at the school profiles on FCPS.edu.
GreatSchools provides the big picture, but understand that there are reasons a score might not tell the whole story. For instance, a school that has an AAP center (gifted/talented) tends to have higher scores b/c of the center. But, if you kid isn't in the AAP center, then that composite score may be shielding the "true" score for the part of the school that your kid attends. Likewise, a school may be sort of a magnet for autism or other disabilities and that will tend to bring the overall passrates down -- but it has nothing to do with how your kid is educated if your kid doesn't have autism. (you can see the number of kids with disabilities on the profiles on fcps.edu and then compare with other schools.)
Likewise, you will usually find that the 5th grade math score is strangely low. That is b/c the kids in adv. math do not take the 5th grade math SOL (at all). So the only kids taking that test are the ones not in adv. math.
There are little variations that can't be assumed just looking at GS. But, if you are looking for high SES, Great Schools ratings are pretty well correlated. I just hope you have plenty of $$ for that house b/c schools in the higher SES zones cost a lot!
OP here. Thanks, this info for how to find and interpret the data is very useful. Based on this and other responses, it looks like the data would be found by county. I'll start researching to find some schools to visit.
