A gold color metal and enamel shield-shaped device with segmented motto scroll attached below the shield, 1 1/8 inches (2.86 cm) in height overall consisting of a gold color metal shield bearing a Torch of Knowledge surmounted by an anvil below a blacksmith hammer and between two lightning-like sparks all of purple. On a purple segmented scroll, the inscription "FIRST" on the dexter segment, "FOR" on the center segment, and "FREEDOM" on the sinister segment in gold letters.
Purple and gold are the colors of Central High School. The Torch of Knowledge, alluding to learning, is indicative of the endeavors of the cadets academically, physically, culturally, and in military science. The anvil, blacksmith hammer and lightning-like sparks are emblematic of the nickname associated with the School, "Purple Pounders." The motto, "First in Freedom," is representative of the School having won numerous Valley Forge Freedoms Awards.
The shoulder loop insignia was authorized 19 June 1978.
