The parents of an elite New Hampshire prep school student who says she was sexually assaulted as part of a game of sexual conquest are suing the school.

The parents' lawyers say St. Paul's School failed to stop a tradition known as Senior Salute, in which upperclassmen kept score of how many younger students they had sex with.

Graduate Owen Labrie (lah-BREE') was convicted last year of misdemeanor sex assault charges. The Tunbridge, Vermont, resident was sentenced to a year in jail. He's out on bail pending appeal.

An attorney for the student's parents says "St. Paul's fostered a culture of misogyny and male privilege" that deprived female students of a "safe and healthy educational environment." The lawsuit seeks unspecified damages.

St. Paul's has not answered an email seeking comment.
