An interesting article in the latest Newsweek examines the impact of several high-profile attempts to improve public education through multimillion-dollar — and, in one case, multibillion-dollar — infusions of cash from well-intentioned donors.

Has this big money made the big impact that they—as well as teachers, administrators, parents, and students—hoped for? In the first-of-its-kind analysis of the billionaires’ efforts, NEWSWEEK and the Center for Public Integrity crunched the numbers on graduation rates and test scores in 10 major urban districts—from New York City to Oakland—which got windfalls from these four top philanthropists.

The results, though mixed, are dispiriting proof that money alone can’t repair the desperate state of urban education. For all the millions spent on reforms, nine of the 10 school districts studied substantially trailed their state’s proficiency and graduation rates—often by 10 points or more. …

… The bottom line? The billionaires aspired to A-plus impact and came away with B-minus to C-minus results, according to the NEWSWEEK/CPI investigation, which was based on specially commissioned data and internal numbers shared by the philanthropists’ foundations.

I’m sure these results shock Terry Stoops.
