Page "Castle Shannon, Pennsylvania" Paragraph 15

Castle Shannon ’ s school system, Keystone Oaks School District, is a " jointure " with the boroughs of Dormont and Green Tree, comprising Dormont Elementary School, Keystone Oaks Middle School and Keystone Oaks High School.

Oddly enough, none of the three communities which make up the Keystone Oaks School District share a common border, and the high school / middle school campus is located outside the district, being situated in the municipality of Mount Lebanon.

Also, a small part of Castle Shannon is actually part of the Bethel Park School District.

Located within Castle Shannon is Saint Anne School, a Catholic private elementary school.
