America's Top 5 Toughest Colleges to Get Into The ranking review website <br />Niche complied the list. The Pittsburgh-based company based it off information from the <br />U.S. Department of Education. It also used data given <br />directly to them <br />from certain schools. Coming in at #1 is Massachusetts' <br />Harvard University. According to Niche, its <br />acceptance rate is just five percent. California's Stanford University, which ranks second, also <br />has a five percent rate. But the SAT range for <br />those admitted to Harvard <br />is a little higher. Coming in at third is the Massachusetts Institute <br />of Technology. In fourth is another tech school, the California Institute of Technology. Ending the domination by Massachusetts and California on the list is Connecticut's <br />Yale University at fifth.
