It’s been two years since Bill Gates left his day-to-day role at Microsoft (MSFT) to concentrate on supervising the Bill & Melinda Gates Foundation–and his new enterprise is booming. Headquartered in a converted check-processing center in Seattle’s Eastlake neighborhood, the 10-year-old foundation plans to move into a 900,000-square-foot campus and visitors’ center near the city’s Space Needle next spring. The Gates Foundation opened a London office this year; it also has offices in Washington, Delhi, and Beijing, and 830 employees around the world, up from about 500 in 2008. With assets of $33.9 billion as of Dec. 31, 2009, and America’s two richest people–Gates and Warren Buffett–as trustees, the foundation plans to spend $3 billion in the next five to seven years on education. If there’s such a thing as a charity behemoth, the Gates Foundation is it.
While its efforts in global health are widely applauded, its record in America’s schools has been more controversial. Starting in 2000, the Gates Foundation spent hundreds of millions of dollars on its first big project, trying to revitalize U.S. high schools by making them smaller, only to discover that student body size has little effect on achievement.
