CalTech, USC, and UCLA ranked among the nations best, according to U.S. News and World Report, which Tuesday released its annual list of "Best Colleges."
Caltech was ranked seventh among national universities tying with traditional rival Massachusetts Institute of Technology.
USC tied for 23rd place with Carnegie Mellon University. UCLA tied for 25th with University of Virginia and Wake Forest University.
Topping the list were Ivy Leaguers Harvard, Princeton and Yale.
A change in how rankings are determined led to some shifts in the magazine's rankings.
More schools were ranked this year, a reflection of both increased consumer demand and improved data collection, Morse said. The survey now displays the rank of the top 75 percent of schools in each category, up from 50 percent. The schools in the bottom tier are displayed alphabetically and not given numeric rankings.
The rankings appear in U.S. News and World Report's "Best Colleges 2011" issue.
The magazine rated universities based in part on the range of available majors and degrees, and their commitment "to producing groundbreaking research."
