Income gap and Academic Gap is Linked. Well, duh.

Scott McLeod's Mind Dump: " The test score gap between the richest 10 percent and poorest 10 percent of students has grown by about 40 percent since the 1960s, according to a study by Stanford University sociologist Sean F. Reardon. That's twice the testing gap between blacks and whites, which shrunk significantly in all income levels, he said."

Which makes sense because the income gap between the richest 10 percent and poorest 10 percent has grown since then, too.

If only someone could figure out why. I have my thoughts, and thoughts, and thoughts, but there's no hard evidence for the mechanism. We just know that income correlates to scores really well, a direct correlation of (.95).

Update: Dan Pink coincidentally chimes in here, too: How to Predict a Child's SAT Scores. Look at the parents tax return.
