Randallstown High School, located at 4000 Offutt Road, is a continuation of the original Randallstown High School that existed from 1918 – 1931 at the present-day site of Randallstown Elementary School. In 1922, the first graduating class from the original Randallstown High School consisted of fourteen (14) students.

From 1931 – 1961, Catonsville, Milford Mill, Franklin, and Woodlawn High Schools served the Randallstown community. Burgeoning enrollments required a new facility.

Randallstown High School opened at our current site in September 1969, with grades ten and eleven plus and elementary school housed temporarily within our walls. The following year, a class of 374 seniors graduated. Randallstown High School qualified for membership in the Middle States Association, and in the fall of 1972, RHS received full accreditation.

In 1975, an open-space area and several more self-contained classrooms were added to the school to help accommodate an ever-increasing enrollment.
