Couple of years back I pointed out that kids within the same school could have pretty different experiences even in suburban communities where everyone pats themselves on the back for being such good liberals and supporting diverse schools. I got more than a few off-line emails about it and lo and behold, they said different things depending on whether the writer was black or white. I thought of that when I read this interesting article in the WaPo last weekend about racial issues at a suburban Maryland school. Well worth a look.
As a policy matter, this is one reason this whole disaggregation of data and transparency business makes people nervous as soon as you scratch below the surface, it inescapably brings these issues to the fore.
