 A visible designation tradition among senior undergraduates and alumni is the wearing of the Aggie Ring , whose design has been relatively unchanged since its introduction in 1894 . Students may order a ring after completing 90 credit hours of coursework , including at least 45 hours at A & M , or after graduation . Graduate students may receive a ring after 75 % of their graduate coursework is completed or after the acceptance of their dissertation or thesis . Though unsanctioned by the University , many students " dunk " their newly acquired Aggie Rings into a pitcher of beer and quickly chug the entire pitcher to " earn " the ring . Some students dunk their rings in alternative substances , including ice cream or nonalcoholic beverages .
