The original Senior High was located on the second floor of a business building at 308 Allegheny Street before eventually moving to 1000 Hewitt Street, or where the current Junior High is today. Prior to 1956, elementary schools in the district included seventh and eighth grade. Overcrowding in Frankstown and Duncansville led to a joint board and the department of Public Instruction to approve an addition to the Senior High, which became the new Junior High school. The Junior and Senior high co-existed and brought relief to the elementary schools since the seventh and eighth grades transferred. However, the increasing student population did not halt and a new Senior High was approved during the 1960s. The existing Junior/Senior High building was then converted to a Junior High, which it remains today.
