Credentials from the National Accreditation Authority for Translators and Interpreters (NAATI) are the only qualifications officially accepted for the interpreting profession in Australia.
There are five main levels of interpreter credentials available through NAATI:
- Certified Conference Interpreter
- Certified Specialist Health/Certified Specialist Legal Interpreter
- Certified Interpreter
- Certified Provisional Interpreter
- Recognised Practising Interpreter
Some TIS National interpreters hold none of the credentials outlined above and are referred to as 'Nil-credentialed'. This occurs in languages where NAATI does not offer certification or recognised practising status. This is generally in low demand languages or languages spoken in new and emerging communities. These interpreters undergo TIS National interview and reference checking processes to ensure their work is of a high standard.
TIS National allocates interpreters in order of the tiered preferences below:
Certified Conference Interpreter
Certified Provisional Interpreter
Recognised Practising Interpreter
For languages where certification is not available, TIS National may be able to allocate a Recognised Practising or nil-credentialed interpreter.
