Research shows that just 3 percent of high-achieving, low-income students attend America's most selective colleges. And, it's not that these students just aren't there -- every year tens of thousands of top students who don't come from wealthy families never even apply to elite colleges. Universities are taking note -- and banding together under something called the American Talent Initiative -- a network backed by Bloomberg Philanthropies, the Aspen Institute and the research firm Ithaka S+R. To join the club, schools have to graduate 70 percent of their students in six years -- a qualification that leaves just under 300 schools in the U.S. eligible. Nearly a third of those schools -- exactly 100 -- have signed on. Their goal? Enroll 50,000 additional low- and moderate-income students by 2025. From a report: Each school has its own goals, too -- many want to increase the number of Pell Grant students on campus, others aim to improve graduation rates -- but they're all on board to share strategies, learn from each other's missteps and provide data to monitor their progress.
