Immaculate Heart encourages students to participate in a wide range of co-curricular experiences that are designed to sharpen their skills and to broaden their perspective of the world around them. Some of these include:

Sports
Athletes compete in the Delphic League in volleyball, basketball, softball, swimming, soccer and cross country.

Community Outreach
The middle school student body adopts primary grade students from a local elementary school and annually hosts a Halloween Carnival, a Christmas Program and an Easter Egg Hunt for them. Students also participate in projects assisting children from Alexandria House and Covenant House and retirees at Holly Royal. Food drives are held and donations are sent to area distribution centers.

Retreats
Each class participates in a day-long retreat held off-campus. Retreats focus on friendship and caring for one another as students explore their relationship with God.
