Seneca opened in 2003 as the district's fourth high school. The school's opening allowed the enrollment level at Lenape High School and Shawnee High School to drop, helping to alleviate the crowding the schools had faced. Based on the number of students who chose to switch to Seneca, there would be 150 students in 2005 in the school's first graduating class.
