In 2001 the boys 1st XI reached the final of the prestigious McCullough Cup and despite a brave performance, they eventually lost in a penalty shoot-out.
Kilkeel High school also competes at rugby. All age groups in the school also compete locally at football. The rugby team reached the high schools cup semi-final in which they played against 5 mile town. The team was beaten narrowly due to refereeing errors.
Pupils from the school regularly qualify for County and "All-Ireland" athletics events including cross-country which the school has experienced great success in, in recent years.
