Among the most notable private non-profit universities are the Ivy League schools, including Harvard, Princeton and Yale, and other highly prestigious institutions such as MIT and Stanford. Most traditional private colleges and universities in the United States operate as non-profits.
The Ivy League includes eight schools: Harvard, Yale, Princeton, Columbia, Cornell, The University of Pennsylvania, Dartmouth and Brown. These schools are consistently ranked as top universities by publications such as the U.S News and World Report, which publishes college rankings annually. Along with Stanford and MIT, they are typically considered to be among the most elite private non-profit universities in the United States. The term "Ivy League" refers to an athletic conference founded in 1954.
