Preferred provider organization
In health insurance in the United States, a preferred provider organization (PPO), sometimes referred to as a participating provider organization or preferred provider option, is a managed care organization of medical doctors, hospitals, and other health care providers who have agreed with an insurer or a third-party administrator to provide health care at reduced rates to the insurer's or administrator's clients.
Certified Protection Officer
The International Foundation for Protection Officers (IFPO) Board of Directors established and maintains a voluntary certification process called the Certified Protection Officers (post nominals: CPO) course, which is based on current and valid standards that measure competency in the practice of private security for Security Officers. The IFPO requires that all programs that offer a certification must be maintained by the individual through a re-certification process. Therefore the CPO certificate is valid for a period of two years, at which time re-certification must be achieved.
