Public Entities and Joint Power Authorities (JPA)
The Office of Self-Insurance Plans (OSIP) authorizes qualified employers to provide their own coverage for workers' compensation liabilities. A public self-insurer is any county, city, school district, special purpose district, joint powers authority or other municipal corporation that has been issued and lawfully holds a valid Certificate to Self-Insure its workers’ compensation liabilities. A Joint Powers Authority (JPA) is a public entity created by an agreement of two or more public agencies with the purpose of forming workers’ compensation liability pooling arrangements. A self-insured JPA has been issued and lawfully holds a valid Certificate to Self-Insure its workers’ compensation liabilities. California has one of the largest self-insurance programs in the nation and has some of the strongest regulations designed to ensure the system protects both employers and employees.
