It is the only high school in the Clyde–Green Springs Schools and mainly serves students from the city of Clyde, the village of Green Springs, and the surrounding area in southern Sandusky and northern Seneca counties.

Upgrades to the building included an auxiliary gymnasium, additional administrative office space, whole-building air conditioning, an enlarged cafeteria, and a new main entrance to the school.

A new wing was added to the building in the late 1990s, including updated science labs, a new media center, and additional classrooms and lockers.

In 2005, the school received a performing arts wing, including rehearsal rooms for bands and choirs and an auditorium, which seats over 800 — enough for the entire CHS student body.

Clyde competes in the Ohio High School Athletic Association (OHSAA) as a member of the Sandusky Bay Conference.
