As the 1960s progressed, the town was compelled to commission a new high school to accommodate further population growth.

In 1971 a new school was constructed at 72 Strobel Road, offering a then-modern auditorium (originally designed as a lecture hall), two-story media center, and athletic complex.

In 1999, Trumbull High School was on national news due to a violent hazing incident involving 10 students of the wrestling team beating, hog-tying, and sodomizing a special-needs student.

An Agrisiceinec and Biotechnology building is located on campus and contains classrooms, labs, a greenhouse, as well as a working farm.

It also hosts 6 tennis courts, 5 baseball and softball fields, and joint soccer and lacrosse stadium.
