Seneca Valley Intermediate High School houses ninth and tenth grades on the secondary campus and holds a unique place in school district history.
Opening in 1964 as Seneca Valley Senior High, the only partially completed school encompassed ninth through twelfth grades and combined the Evans City and Zelienople high schools. Due to a growing population, the current Senior High School was built in 1994 to include eleventh and twelfth grades, and the original Senior High became the Intermediate High School.
Through these more than fifty years, the Intermediate High School’s faculty, staff, and administration have continued to dedicate themselves to providing excellence in education for the students they serve.
