Inter-Academic League

The Inter-Academic League (commonly known as the Inter-Ac) is an inter-scholastic athletic conference. The high school sports league consists of selective private schools in the Philadelphia area and surrounding suburbs. The schools were organized into a conference early in 1887 when they came together as the Interacademic Athletic Association (the name was later shortened to its present configuration). Two initial sports offered by the league were football and track and field. Early members were Germantown Academy, Haverford Grammar, Penn Charter, De Lancey, Friends' Central School, Swarthmore High School, and Episcopal Academy. In the first decade after the turn of the century the league featured a full calendar of sports, adding ice hockey, baseball, tennis, and basketball.

Two of the league's members - William Penn Charter School and Germantown Academy - share the nation's oldest continuous football rivalry, celebrated every year during GA/PC Day.
