Hello Beccas! Well from my understanding, A "certificate" of technology in Culinary Arts is a document certifying completion of technical classes directly relating to your major...which is culinary arts/restuarant managment. The Degree would be a document certifying the completion of the technogly classes plus basic academic classes like psychology, math, english, speech and the such, what ever is in the degree plan outline of courses. As for the AOS, i can't think what O stands for, but the degree plan i am in is AAS, which is an Associates of Applied Science in Culinary Arts. Maybe somone will add to this post and explain what the "O" stands for. Hope this was any help, and welcome to the Cafe!
