When additional insurance is required, student organizations will be required to provide a Certificate of Insurance, also known as a COI, to the Office of Student Involvement. A certificate of insurance (COI) is a document used to demonstrate evidence of insurance to another party and to provide information about specific insurance coverages. The COI gives the receiving party information such as types of insurance policies carried, lists the insurance companies providing the coverage, shows the insurance limits and deductibles, and the policy effective dates.
