K DeRosa draws the chart that I proposed.

Here is the chart for 497 school districts in Pennsylvania for 2005. On the X axis I have the percentage of students in the district that do not receive free and reduced meals. On the Y-axis I have the pass rate for PA’s PSSA 11th grade exam (math and reading).

…The overperforming schools [the ones above the regression line] actually spent less on average. Go figure.

I’m supposed to get the Maryland data from a friend today.
