csen asked: I just found your "Three Atlanta Schools to Watch" post. Where can one find demographic data by school/grade?

The best place I know of is on the Georgia Department of Education website.  In my article, the data came from the Governor’s Office of Student Achievement.  Here’s the link to the Georgia DOE source:  http://www.doe.k12.ga.us/Technology-Services/Data-Collections/Pages/Home.aspx
