Named after John Marshall, the fourth Chief Justice of the United States, the school was established in 1968 as a result of the consolidation of three smaller schools in Marshall County, West Virginia: Moundsville High School, Union High School and Sherrard High School. At its inception, John Marshall boasted one of the few modular scheduling systems in the United States. In the 1994-1995 school year, John Marshall High School ran a traditional eight period day offering students half-credit one-semester courses and full-credit two-semester courses.
The student body of John Marshall High School numbers over 1,200 in grades 9 through 12, making it one of the largest secondary schools in West Virginia. The curriculum is comprehensive, including a county-wide vocational program. The school also offers dual-credit college courses and boasts a fully operational College Board Advanced Placement (AP) Program.
