The Intermediate Unit IU1 provides the district with a wide variety of services, such as: specialized education for disabled students, state-mandated training on recognizing and reporting child abuse, speech and visual disability services; criminal background check processing for prospective employees and professional development for staff and faculty.

The historic school grounds in North Franklin Township date back to the 1850s when Joseph McKnight built a home on top of a hill overlooking the then-borough of Washington, Pennsylvania.

This twenty-five room Italianate mansion called Spring Hill now functions as the district's administrative offices.

[11] Spring Hill was purchased by William Smith, a prominent Washington dry goods merchant, as the new home for his son.

[12][13] William Wrenshaw Smith was a devout Episcopalian and longtime vestryman at Trinity Episcopal Church, then located on Beau Street near Washington and Jefferson College.

During the 1860s, Smith worked alongside John Barrett Kerfoot, newly elected Bishop of Pittsburgh, to create a boys’ school following the curricular model of famed priest-educator William Augustus Muhlenberg.

[14] In this model, “the school was to be like a large family with a priest as rector serving as father-figure in loco parentis.” Trinity Hall operated from 1879 to 1906 attracting members of prominent regional families including Heinz, Carnegie, Kammerer, and LeMoyne along with a grandson of President Grant.

This included a “military department” for purposes of exercise and a more generic Protestant Christianity in place of Muhlenberg's strictly Episcopalian church school model.

Then in 1925 the townships of Amwell, Canton, North Franklin, and South Strabane purchased the Trinity Hall property for repurposing as a joint public high school.
