The official name of the school is Rock Hill Senior High School, however, in many instances it drops the 'Senior'; and it is mostly used ceremonially, for graduations and business. The reasoning for this is that the school used to feature 10-12 grades, and the junior high school featured 7-9. After the changes made by the Board of Education, the high school added ninth grade and the junior high added the sixth grade. The junior high school changed its name officially to "Rock Hill Middle School," but the high school never followed suit. There are several reasons behind this, being that it is the only high school in the country to have the name, (there are other Rock Hill High Schools, but there are no other Rock Hill Senior High Schools), as well as tradition.
