Must-read new report on high school dropouts

Jay Matthews:

I have long considered high school drop-outs not only the least soluble of our education problems but the least clear. School districts have traditionally fudged the numbers, reporting their drop-out rates as only 5 or 6 percent, a grossly deceptive one-year rate.
The National Governors Association and other policymakers, ashamed of this charade, have put an end to it. Everyone is switching to a four-year drop-out rate, the percentage of ninth-graders (about 31 percent nationally) who do not receive diplomas four years later. The improved data has not only raised the level of the debate but also made possible a new report with some unnerving revelations about graduation rates.
My wife made the mistake of letting me go with her to her office last Sunday to catch up on work. While there I read the new Education Week report, “Graduation by the Numbers: Putting Data to Work for Student Success,” and kept squealing at one statistical surprise after another. I insisted on reading each one to her, delaying her efforts to get back outside on a nice weekend day.
