No definitive statement can be made concerning the credentials or experience levels of arbitrators, although some jurisdictions have elected to establish standards for arbitrators in certain fields. Some independent organizations, such as the American Arbitration Association offer arbitrator training programs, and arbitrators may cite their completion of that training as a credential. Generally speaking, however, the credibility of an arbitrator rests upon reputation, experience level in arbitrating particular issues, or expertise/experience in a particular field. Arbitrators are generally not required to be members of the legal profession.
