National Accreditation Authority for Translators and Interpreters (NAATI) is a national standards body administered by the Commonwealth, State and Territory Governments of Australia.
They are responsible for the assessment of language proficiency and the accreditation of interpreters. The accreditation process classifies interpreters according to different levels of proficiency in Languages Other Than English (LOTE).

For mental health settings, NAATI Certified Specialist Interpreter credentials (formerly known as Level 3) are required.
Interpreters with preferred credentials may not always be available, particularly in new and emerging communities where NAATI does not as yet offer testing. In such instances, it may be required to work with interpreters with Certified, Certified Provisional, or Recognised Practicing credentials. Be honest and open with all parties to determine what is possible and realistic.
