Strath Haven High School (also abbreviated as SHHS) is a four-year public high school in Wallingford, Delaware County, Pennsylvania, enrolling about 1,200 students. SHHS is the only high school in the Wallingford-Swarthmore School District. The school exhibits particular excellence in its special education program, connections to a local college and technical schools, and strong music and football programs. As of 2020, the current principal is Greg Hilden. History Strath Haven High School is the product of a 1983 merger between the former Swarthmore High School and Nether Providence High School. In 1971, Pennsylvania state officials had determined that Wallingford and Nether Providence school districts had too small enrollments to maintain an independent existence. By 1980, enrollment in Swarthmore High school had dropped to the point that maintaining separate middle and high schools was no longer feasible. Because it had smaller enrollment, the district closed Swarthmore High over bitter and acrimonious public protest. (Many parents, opposed to the decision, attempted to form a private high school on the former Swarthmore campus.) To mollify those opposed, the district officially closed Nether Providence High School as well, and created an entirely new school on the former Nether Providence campus, named after Strath Haven manor on the Thomas Leiper Estate. In 2005, the School District of Philadelphia selected then-principal Albert Bichner as Superintendent of High Schools. In response, the school promoted assistant principal Mary Jo Yannacone, who remained principal until June 2018, when she became Assistant Superintendent for Springfield School District. The school was then temporarily led by Andrea LaPira until the selection of Greg Hilden in 2020. Overview The typical graduating class is approximately 300 persons. Former principal Al Bichner organized Strath Haven along the theme of the "Five A's," meaning academics, arts, athletics, altruism, and activities. An oft-cited "Five A's" figure is that around 80% of Strath Haven High School students participate in athletics, music, the arts, and a host of extracurricular clubs. All students are required to complete four years of study in major subject areas, but also have limited freedom to select "elective" classes. Strath Haven provides guidance counselors to assist in course selection and college and career planning. A full-time psychologist and communications specialist are the core of a Student Assistance Program providing help to students at risk. Football The school competes in the twelve-team PIAA Central League, winning 10 times between 1996 and 2010. Between 1983 and 2022,
