COI Diploma study guide

COI Diploma · Work through your exam, one topic at a time.

The COI Diploma is a professional credential for people who issue, review, or rely on certificates of insurance - agency account managers and CSR staff, compliance and risk-transfer analysts in construction and facilities, contract administrators, and underwriters who field certificate questions daily. It tests whether you can read a certificate and the underlying policy together and explain what is and is not actually being evidenced. The COI Diploma study guide has 7 sections and about 2,526 words.

01

Additional Insured Endorsements and Contractual Risk Transfer

Evidence of Coverage, Verification, and Compliance
