Interactive graph and article discusses achievement gap between low income and upper income 6th graders (up to four grade levels!).
Using the interactive graph, what caught my attention is the 100% ignored achievement gap between the solid middle class suburban schools and upper middle class suburban schools. I noticed a 1.5-2.0 grade level gap between these 6th graders! How many middle class parents suspect the 6th graders in the nearly wealthier district are two years ahead?
