Welcome to Harriton High School!
Harriton has twice been recognized for academic excellence as a "Blue Ribbon School" by the state of Pennsylvania and the U.S. Department of Education!
Harriton High School has once again earned the No Place for Hate designation from the Anti-Defamation League for their commitment to celebrating diversity, championing inclusion, and challenging bias and bullying at all levels!
Students representing LMSD's National Society of Black Engineers (NSBE) Jr. chapter turned in a remarkable performance at the 2026 NSBE Annual Convention in Baltimore, capturing the VEX V5 Robotics Tournament Championship, the VEX V5 Robotics Skills Award and the VEX V5 Excellence Award to earn a spot in the World Championships!
Harriton High School recently hosted its annual International Night, a vibrant celebration of the many cultures that make up the Rams community! This year’s event highlighted the traditions of two dozen countries through international cuisine, activities and interactive experiences that sparked curiosity, deepened understanding and celebrated diversity.
Harriton's auditorium was filled with community spirit as students took the stage for the 19th Annual Dr. Harriton talent competition—an evening that raised $70,000 for charity and saw senior Julia Paulat make history as the first female champion in the event’s 19-year run!
As part of their Black History Month programming, Lower Merion and Harriton high schools each hosted their own African American Read-In (AARI), joining a national literacy initiative that celebrates African American authors and the power of storytelling.
