On a black shield edged with a 1/8 inch (.32 cm) red border 3 1/2 inches (8.89 cm) in height by 2 1/2 inches (6.35 cm) in width overall, two red devil heads respectant, each grasping a red vertical trident between them, all below the inscription "RED DEVILS" in red letters.
Black and red are the school colors. The red devil is the school mascot. The two faces suggest the two county schools that combine to make Randolph-Clay. The devils grasp one trident signifying unity of the two student bodies and also reflecting teamwork, an important part of leadership training in the ROTC program.
The shoulder sleeve insignia was approved on 4 November 1994.
