School Overview

Harriton Senior High School sits in Rosemont, a quiet, tree-lined corner of the Main Line where historic stone homes and easy SEPTA access to Philadelphia make for an exceptionally livable suburban life. The school consistently ranks among the very best in Pennsylvania, drawing families who want rigorous academics — think strong AP offerings and a college-prep culture — without sacrificing the tight-knit feel of a community school. If you're relocating to Montgomery County and academics are at the top of your list, the Lower Merion district in general, and Harriton in particular, should be your first stop.
