Attached above the shield a Green scroll edged with a 1/8 inch (.32 cm) Black border and inscribed "FARMINGTON" in White letters.
The school colors are green, white and black. The Zia sun symbol alludes to the home State of the school. The mountains represent the predominant local landmark of Shiprock. The quartered shield suggests the "four corners" area of the United States, a unique and distinctive phenomena reflecting the cadets' dedication to community and country. The four pointed mullet represents Farmington.
The shoulder sleeve insignia originally approved on 20 March 1998 was amended to change the color appearing in sinister base of the shield from Irish Green to Golden Yellow on 18 August 1998.
