The Sloan Consortium, based on data collected from over 2,200 U.S. colleges and universities, reports that nearly 3.2 million students took at least one online course during 2005 (a significant increase over the 2.3 million reported in 2004). According to the same report, about two-thirds of the largest institutions have fully online programs.[11] In 2010, more than 6 million students were taking at least one course online.[20] As of 2013, the number of students enrolled in online courses had risen to over 6.7 million.[21]
