Killian Hill Christian School is a member of the Georgia Association of Private and Parochial Schools (GAPPS). The purpose of GAPPS is to promote high school and middle school athletics for students in Christian and independent schools, and give opportunities for athletic competition to athletes who may receive a nontraditional education. The goal of GAPPS is to create an environment where high school and middle school students can compete at their levels yet still be encouraged to grow in their faith.
Some middle school (MS) sports are played as independent or within a metro–Atlanta middle school league. KHCS has the following sports available for students:
Fall – Varsity Boys Soccer, Co-ed Cross Country, MS and Varsity Girls Volleyball
