Louise Losos has spent more than two decades as a public educator, including time at Ladue High School as a teacher and five years as the assistant principal at Parkway West High School. With Louise Losos serving as the principal, Clayton High School was named by Newsweek as one of the top 100 schools in the nation and the top school in the state of Missouri.

In May, Newsweek released its annual list of the top high schools in America. The 2013 list included 2,000 high schools that have reputations for turning out college-ready students. The list is computed after a number of focus areas have been taken into account: the high school’s graduation rate, the percentage of students accepted into college, the number of students enrolled in AP/IB/AICE prep-classes, and the school’s average test scores. This year’s list was topped by the Carol Martin Gatton Academy of Mathematics and Science in Kentucky, while Florida is home to four of the nation’s top ten schools.
