​The junior high curriculum at Greensburg Central Catholic is designed to prepare students for high school. Core subjects, such as language arts, mathematics, science, and social studies, are taught, as well as courses in religion, visual and performing arts, physical education, and three world languages. Some incoming eighth grade students also complete summer assignments to prepare them for the new school year.

In addition to the curriculum, students can participate in more than 10 junior high clubs and 9 junior varsity sports.

Junior high students receive all the same benefits as Greensburg Central Catholic senior high students, including access to the library, and support services and counseling provided by Catapult Learning Services.
