You can change the NAATI test language if the test date is more than 7 days from the date of change. There is no fee to change and no penalty. If the test date is within 7 days from the date of change, a 100% penalty (i.e. $800) will be applicable. Language requests can be submitted to info@naati.com.au. To change the language a second time, you should withdraw your application, submit a refund form (eligible refund is 75%) to finance@naati.com.au and then submit a new application.
