Mt. Lebanon High School is on the Washington Post's list of America's Most Challenging High Schools. Only 31 high schools in Pennsylvania and six schools in Western Pennsylvania are listed. This is the Washington Post's annual rankings of how successfully schools challenge their students. According to the Washington Post, "The methodology used to develop the list ranks schools through an index formula that takes the number of Advanced Placement, International Baccalaureate and Advanced International Certificate of Education tests given at a school each year, divided by the number of graduating seniors." Congratulations to our high school students, faculty and administration on this recognition.
