Mediator accreditation in Australia

Mediator accreditation gives you a recognised qualification that shows you've met training and competence standards and are committed to continuous learning. It gives you the credibility to establish and grow yourself as a mediator.

National Mediator Accreditation Standards (NMAS)

The National Mediator Accreditation System (NMAS) is a voluntary, industry based scheme introduced in January 2008. Since then, NMAS accreditation and practice standards have been widely adopted across Australia. Neighbouring countries in the Asia Pacific region also use NMAS on occasion as the required standard for mediators.

The implementation and development of NMAS is overseen by the Mediator Standards Board (MSB). Organisations designated as Recognised Mediator Accreditation Bodies (RMABs) can accredit mediators to the national standards. Resolution Institute is a Recognised Mediator Accreditation Body (RMAB) under the National Mediator Accreditation System (NMAS)

Elder Mediation Certification

The Elder Mediation International Network (EMIN), the Elder Mediation Australasian Network (EMAN) and the Resolution Institute have recognised the need for both a national and international standard for certification of mediators specialising in issues of aging – one which assures the competency of mediators and speaks with a strong and credible voice.

Health and mental health agencies and government and non-government organisations involved with issues of ageing are well positioned to advocate for elder mediation as a valuable service for the older people, families and others utilising their services. Referral to qualified, informed professionals who adhere to a recognised standard of practice is necessary to enhance trust, communication, and the welfare and safety of older people, their families, and significant others in the older persons’ networks.
