The Yale School of Management will not be in the top 10 of this year’s U.S. News and World Report ranking of the best business schools in the nation.

Though U.S. News will publish the full list of schools on March 12, it released the top 10 business schools in alphabetical order in a Tuesday teaser. The only school included in last year’s top 10 that did not make the cut this year is SOM, which was replaced by NYU’s Stern School of Business. Stern ranked 11th last year, just one place behind SOM for last year’s rankings.

John Byrne, a former executive editor of Bloomberg Businessweek magazine who designed the publication’s business school rankings, said in a post on his business school news site “Poets and Quants” that SOM’s drop is “small yet surprising,” given that SOM Dean Edward Snyder has been trying to improve the school’s standing in rankings.

Though no school would want to fall out of the top 10, Byrne said SOM’s drop might not reflect any substantial setback for the school.

“The numerical rank of a school is often decided by fractions of an underlying index number with little, if any, statistical significance,” Byrne said in the post. “So it is likely that Yale’s drop is inconsequential, in terms of the actual underlying data used to crank out the ranking.”

Bloomberg Businessweek gave SOM the 21st ranking in its 2012 biennial ranking of full-time U.S. MBA programs, and the Financial Times ranked SOM 16th in its 2013 global rankings.

The other nine schools that made the top 10 business schools cut this year are Columbia, Dartmouth, Harvard, MIT, Northwestern, Stanford, UC Berkeley, University of Chicago and the University of Pennsylvania.
