There are six main types of ombudsmen: Classical, Advocate, Hybrid, Executive, Legislative, and Media. Classical ombudsmen investigate complaints, may be elected or appointed, and have authority to conduct investigations. Advocate ombudsmen represent the public interest, often in organizations like long-term care facilities. Hybrid ombudsmen use informal methods to resolve complaints between public and private sectors and can publish reports. Executive ombudsmen work to improve organization performance, either publicly or privately. Legislative ombudsmen concern actions of government entities. Media ombudsmen promote transparency, investigate news complaints independently, and explain roles and obligations.
