Prerequisite pathway options

There are four prerequisite pathways outlined below which explain your options.

The pathway you choose will determine what documents or evidence you need to supply with your application to NAATI, and whether you need to sit any screening tests.

When you are ready to apply, go to the ‘Apply, reschedule or cancel‘ tab for important information.

Read the detailed candidate instructions under the ‘Prepare for your test‘ tab. You can refer to our glossary of certification terms for any terms you don’t understand.

Test assessment & results

At least 2 NAATI examiners will independently assess your performance in the test. They will assess each task separately, using assessment rubrics with 5 bands (with Band 1 representing the highest level of performance and Band 5 the lowest). Your task performance will be marked against each criterion, which are the same for all task types, as outlined below.

For each task, NAATI examiners will assess your:

  • Transfer competency: Meaning transfer skill, Application of interpreting mode, and Rhetorical skill.
  • Language competency: Language proficiency enabling meaning transfer into the target language.

Refer to our language policy to understand how the examiners will assess your use of language in your test.

You need to achieve at least Band 2 for each criterion, and you must pass all six tasks to pass the test. To be awarded the Certified Interpreter credential, you must pass both the Certified Provisional Interpreter test and Certified Interpreter test.

You can read the assessment rubrics here.

NAATI aims to issue results within 8-10 weeks of the test date. We will issue results as they are finalised, so some candidates will receive their results earlier than others even if they sit the test on the same day.

To be awarded the Certified Interpreter credential, you must pass both the Certified Provisional Interpreter (CPI) test and Certified Interpreter test. 

  • If you already hold a CPI credential, you will be awarded a Certified Interpreter credential if you pass the Certified Interpreter test. 
  • If you pass the Certified Interpreter test, but haven’t yet passed the CPI test, you will not receive the Certified Interpreter credential until you have also passed the CPI test. 

You must also pass any prerequisite screening tests (Ethical Competency and/or Intercultural Competency).

If you attempt all tasks and pass at least four of the six tasks but fail this test overall, you are eligible to apply for a supplementary test. 

You must apply for the supplementary test from your myNAATI account within 30 days of receiving your test results. The supplementary test will involve re-sitting only the task type(s) that have been failed, but on a different topic. 

If you pass this supplementary test, and you already hold a Certified Provisional Interpreter credential, NAATI will award you the Certified Interpreter credential. If you fail the supplementary test, this means you have failed the Certified Interpreter test. You can apply for another Certified Interpreter test with NAATI if you want to sit the test again.

Please note: Rejecting a test session means that you will lose your place in that test session, and it may be quickly booked by another candidate. There is no guarantee you will be able to select the same test date again once you have rejected it.

It is not possible to reschedule a test within 2 days of the test session unless the candidate provides evidence of hospital admission, serious injury or an accident. This is because we “lock in” the test sessions to enable planning and preparation.

If you have been admitted to hospital, or suffered a serious injury or accident, you must provide evidence to info@naati.com.au by 8am (AET) on the test day at the very latest. The medical certificate or hospital admission must state the nature of the illness.

If your test is within the next 2 days and you can no longer attend for another reason, you will need to cancel your application (see below) and apply again. 

Please follow the instructions below if you want to cancel your test.

If you decide to sit the test at a later date after cancelling your initial application, you will need to submit a new application. This will include selecting a new test session and paying the full test fee.

If your test is more than 2 days away 
  • You will be eligible for a refund of 75% of your test fee if you cancel a test more than 2 days before the test date.
  • Follow the instructions on applying for a refund through your myNAATI account.
If your test is within the next 2 days 
  • To cancel a test scheduled within the next 2 days, you must email us at info@naati.com.au with your customer number so that we can cancel your test for you. You cannot reject your own test session in myNAATI if your test is scheduled within the next 2 days.
  • You will not receive a refund if you cancel a test within 2 days.

If you do not attend your test on your scheduled test date, this is considered a cancellation and no fees will be refunded.
