The Lone Star Emergency Services Academy Emblem was designed in accordance with Air Force Instruction AFI 84-105. Group and wing emblems are shield-shaped, while squadron and activity emblems are on a disc.

The heraldic blazon (the unique language used to describe heraldic emblems) is as follows:

On a circular shield sable with a diminutive border sable, three vertical arrows gules within larger arrows argent in turn inside arrows azure, spanned by an American Eagle in colors proper, all surmounting an image of the earth as seen from space proper, on which are over-imposed a ribbon or and the Texas state flag in the outline of the state of Texas proper. On upper tab the words LONE STAR argent separated by a star argent. On lower inside border, the words EMERGENCY SERVICES ACADEMY argent.

In plain English, the above means:

On a circular black shield with a thin black border (black symbolizing constancy and grief as brought on by disaster), three vertical red arrows within larger white arrows in turn inside blue arrows (echoing the National Colors, red symbolizing strength and magnanimity; white, purity, peace and sincerity, and blue truth and loyalty), spanned by an American Eagle (denoting CAP's Congressional charter) drawn in its natural colors, all above an image of the earth as seen from space (symbolizing constant vigilance through high technology) on its "blue planet" colors, on which are over-imposed a gold ribbon (gold symbolizing generosity and nobility of purpose) and the Texas state flag in the outline of the state of Texas (in red, white and blue), denoting Texas Wing's mandate to stand vigil over its State. On its upper tab the words LONE STAR in white, separated by a single white star (the State's nickname). On the lower inside border, the words EMERGENCY SERVICES ACADEMY in white. The white lettering evokes purity, peace and sincerity.

The emblem design is derived from the National Emergency Services Academy's, as adapted by Lt. Col. Brooks Cima, Texas Wing Director of Emergency Services, and Capt. Arthur E. Woodgate, Southwest Region Director of Public Affairs.
