Wissahickon High School and Upper Dublin High School were included in Philadelphia magazine’s article “The 40 Top-Rated Public High Schools in Philadelphia and the Suburbs.” Overall, six public high schools in Montgomery County made the list (Wissahickon, Upper Dublin, Lower Merion, Harriton, Lower Moreland, and Methacton).
To determine the list, the magazine used “the latest publicly available data from the Pennsylvania and New Jersey departments of education and the National Center for Education Statistics; numbers above have been rounded to the nearest whole.”
