From EdWeek:
K12 Inc. is on a remedial course of action after learning hard lessons about managing student enrollment and addressing public criticism about the academic performance of its students. The Herndon, Va.-based company—the largest for-profit provider of precollegiate online learning and one of the few publicly traded companies in the K-12 marketplace—showed an inability to enroll as many students as anticipated for the 2013-14 school year. That sent its stock into a nose dive earlier this month—a 38 percent drop that also came three weeks after a prominent hedge fund manager, Whitney R. Tilson, took a position that the company was overvalued.
