The Society of Registered Professional Adjusters is the organization implemented to oversee the qualifications and designations of Registered Professional Adjusters (RPA).  The Society was formed by industry professionals that felt continuing education was critical and that there needed to be a designation that recognized the professionalism of an adjuster.  The Board of Directors is made up of insurance company top management and support organizations, independent claims adjusters, and attorneys that work directly with the industry.  It is the first and only designation formed by and for the insurance claims professional.
