School Overview

Radnor Senior High School sits in the heart of the Main Line, one of the most storied suburban corridors in the Philadelphia region, where tree-lined streets, historic neighborhoods, and a strong culture of academic achievement have long attracted families who take education seriously. With near-perfect scores across English, math, and science, Radnor consistently ranks among the very best public high schools in Pennsylvania — and the community clearly invests in keeping it that way. Families who settle in Radnor Township tend to be drawn by the whole package: an engaged school district, easy access to Philadelphia via the Paoli/Thorndale rail line, and a tight-knit borough feel that makes it genuinely feel like a place to put down roots.
