That year, a group of 45 students attended the first classes on the second floor of the Imbusch Building in downtown Cullman, which housed the W. O. Kelley General Store.

Fortunately, the businessmen of the City of Cullman rallied together to raise the funds needed to keep the school open.

It was at this time that the word "county" was dropped from the name to indicate the school only served students living within the city limits of Cullman.

[7] The present-day campus of Cullman High School has been in the works for the past 2 years at the Thirteenth Street site.

The new Cullman High School expanded campus when completed, will support nearly 2,000 students and include updated facilities.

Phase I of the Cullman High School Expansion Project was completed in the fall of 2010, bringing with it a new $4-million auxiliary gymnasium, a 5,000 square feet (460 m2) science building addition and a new football stadium with an artificial turf field and an 8-lane track.

[8] Phase II will begin in late 2010 or early 2011, and includes a new two-story library and media center; conversion of the current library into a state-of-the-art business/career technical center; a second-story addition to all of the academic buildings and administration; a new school entrance and lobby; an expanded cafeteria; an outdoor amphitheater outside the cafeteria; complete refurbishing of all academic buildings, the main gym, and the auditorium; expanded student and faculty parking; and potential other expansions and additions.

It was the first time in school history for a Cullman football team to make it to the fourth round of the state playoffs.

The Cullman High School Bearcat Band performs at every school football game throughout the year, as well as marching in the annual fair parade, performing at the Cullman County Band Exhibition, and participating in three contests per year.

[10] The auxiliaries (color guard, dance line, and majorettes) are known throughout the state and have won many best in class awards.

In 2007 the CHS Band marched in the Veteran's Day parade in New York and appeared on CBS Early Show.
