DEFINITION of 'Associate In Insurance Services (AIS)'. A designation earned by insurance professionals and conferred by The Institutes. The Associate in Insurance Services, or AIS, designation indicates that the holder has demonstrated knowledge of the insurance industry, insurance principles and practices, as well as insurance contracts and how they should be managed.
