1. Affidavit of service

Law & Legal · Litigation Abbreviations

Sworn statement by a process server or other person describing how and when legal papers were delivered to a party. It is filed with the court as evidence that service was proper.

Example: The process server's AOS says the summons was left with the defendant's adult daughter at his home.

Many states require an affidavit for service of the initial summons and complaint, while later papers can use a simpler certificate of service signed by counsel. In federal court, Rule 4(l) requires proof by the server's affidavit unless a marshal made service. In English procedure, AoS instead means acknowledgment of service, a defendant's response form.

2. Associate in Occupational Studies

Education & Academia · Degree Abbreviations

Associate degree awarded mainly by career schools, especially in New York, for intensive occupational programs such as culinary arts, automotive technology or audio engineering. The Culinary Institute of America awards its two-year culinary and pastry degrees as the AOS.

Example: The CIA's AOS in baking and pastry arts includes an externship at a working bakery or restaurant.

Unlike the AAS, the AOS typically contains little or no general education, so its credits rarely transfer toward a bachelor's degree. Employers in hospitality and the trades value it for the hands-on hours it represents rather than for academic content.
