The first school in Odenville (then called Hardin's Shop) was a log, one-room school building built in 1864. Odenville has had other community schools in the area since the middle of the 19th century, including the Friendship School, Low Gap School and Branchville School. The first Odenville School, a wooden structure established by Mr. Jim Hardin and Thay Bayer, burned in 1907. Students had to meet in churches during construction of a new school. On July 18, 1908 the original St. Clair County High School building was constructed. A historic monument engraved with the names of the original county leaders responsible for the construction of this first high school stands in front of what is now Odenville Middle School. This school was a K-12 school. The building itself was a field stone building and was used until the 1950s, and still stands and is used by the St. Clair County Schools transportation department. On May 1 of the same (1908) year it was awarded the first high school in St. Clair County, meaning it graduated twelfth-graders. When doors were opened SCCHS had only 25 students. There were also several elementary one-room schoolhouses in the area during that period. They were closed over an extended period. As each one closed, their student body combined with St. Clair County High. The last one to close was the Friendship Community School. In 1912, SCCHS held its first graduation ceremony.
In the 1970s a separate large elementary building was constructed separating the elementary from secondary students. By 1998, a newer, larger elementary building had to be constructed due to climbing enrollment.
Today, SCCHS is led by Principal Mike Howard and Assistant Principal Brandon Taylor and Co-Assistant Principal and Athletic Director Carl Mims. In 2007, construction of a new high school building was completed and students were moved in. This building was one of the most state-of-the-art facilities in the state of Alabama. This brought more students, and more room to hold those students along with new opportunities for students, parents and administrators. Enrollment continues to climb.
Odenville's schools are part of the St. Clair County School system, led by superintendent Jenny Seals.
