Distance learning is here to stay. Initially on the fringes of formal education, online colleges, courses and degree programs have quickly become mainstream. Even traditional campus-based institutions have incorporated online learning into their curricula. In 2013, seven million college students — nearly 50 percent of all those enrolled — took at least one online class, with an estimated 20 percent earning an entire degree program remotely. The Sloan Consortium reports that 74 percent of today’s academic leaders rate the educational outcomes of online learning as equal to or superior to those of face-to-face systems. More recruiters than ever before are embracing online credentials.
