Drive Smart is a driving course, taught by the SDOC School Resource Officers, that all students must take prior to driving and parking on one of our campuses. This four-hour course will be taught at each of our three high schools and is designed to help teens gain the knowledge to drive defensively. The Drive Smart driving course will take the place of the requirement for Alive at 25. A student may still take the Alive at 25 course instead of Drive Smart.  Cost of the course is $25.00, this money will be used to pay the instructor and repaint parking lots on all of our campuses.
Registration information will provided soon.

Palmetto's Finest logo

Seneca High School has been named Palmetto’s Finest High School in South Carolina! Our students, faculty, and staff have had a tremendous year academically, artistically, and athletically. In addition to being named Palmetto’s Finest, a high point this year was accomplishing a graduation rate of 88.9%.  We are proud of our diverse student population and the communities that each student represents. We are equally proud of Seneca High, a school that is a direct reflection of our involved and supportive community. Join me in applauding the efforts made by our student body, faculty and staff, and community stakeholders as we continue to pursue our goals as the best high school in South Carolina!
