Throughout the year, students participate in many traditions, some dating to the earliest days of the school. The classes compete during Spirit Week and the competition culminates on Field Day. The school hosts an annual fundraiser, the Spirit Gala, in the fall. Homerooms adopt a family and provide Christmas baskets during December. The gifts are blessed at Golden Mass, usually celebrated by the Bishop. March is Mission Month, in which students raise money for local, national and international charities through crafts sold by seniors and other school-wide fundraisers. Arts Fest provides students a chance to show off their talents; this day-long event includes indoor and outdoor performance assemblies, a concert from a local professional group, and hour-long workshops in various areas taught by teachers and other professionals. In May, many girls take their fathers to the Father Daughter Dinner Dance. During May, the juniors receive their class rings. Mercy is known for its unique school ring. While most high school rings incorporate gems, the center of the Mercy ring is dominated by the school crest. The shank on both sides of the ring feature a rising sun with the open Bible among the rays. After their ring ceremony the Juniors attend Junior Prom in the evening. Toward the end of May, May Day is held. A senior is elected May Queen and has a court of peer elected juniors and seniors who help her organize the ceremony. After Mary is crowned in the Grotto, the seniors prepare for Senior Ball. The year ends in June with the Moving Up Ceremony where the classes provide advice to the classes below them. At the end, the student body moves up seats in the auditorium and the seniors join hands and walk to the stage. Retreats are also a part of Mercy tradition. Freshman retreat is held in school, while sophomore and junior retreats are a day long event. Senior retreat is an overnight at Camp Stella Maris and is one of the last times the senior class will spend together.
Extracurriculars
Mercy offers many extracurriculars. There is a fall musical, a spring drama, and a Children's Theatre production. Students may lead the school through Student Council or Campus Ministry Board. Mercy is home to the Catherine McAuley chapter of the National Honor Society, as well as groups that volunteer with inner city children and elder Sisters of Mercy. Youth and Government as well as Mock Trial give students real life skills in practice settings. Robotics, Masterminds and Math League test students' knowledge, while Veritas, The Quill, and Mercedes give students a creative outlet. Students can join the Ski Club, Run Club, or Boxing Club. Habitat for Humanity and Friends of Rachel help students get involved with the community both in and outside of school. Improv Club and Dress-a-Girl are some of the newer options for students. There are also a choir, a show choir and an orchestra for the musically inclined.
