There's a crispness in the air, pumpkin spice is around the corner, and many are headed back to school.

This means it's time for the Princeton Review to rank the nation's top party schools. If your kid just left for college, you should stop reading right now, and just know that your child is different, they are studying in the library and not taking part in any of these shenanigans.

BYU, for the 19th year in a row, is the nation's most "stone-cold sober" on the list. Behind BYU on the "Stone-Cold Sober" list of schools, you will find the United States Air Force Academy in Colorado Springs.

The criteria for top party school or stone-cold sober are based on a combination of "low personal daily study hours(outside of class), high usages of alcohol and drugs on campus and high popularity on campus of frats/sororities."

Here are the Top Party Schools for this year:

University of Wisconsin-Madison
West Virginia University
University of Illinois at Urbana-Champaign
Lehigh University
Bucknell University
University of Iowa
University of Mississippi
