UEENEEH016B – RPL ASSESSMENT

RPL Assessment Tool

RPL recognises any prior knowledge and experience and measures it against the qualification in which you are or wish to be enrolled.

The process:

complete the Self Assessment checklist included in the RPL Assessment Tool with as much information as you can. Please fill in the “grey” shaded areas.

If needed, contact one of the RPL Assessors listed below. They will be able to give you more advice on the type of evidence that you will need to provide.

collect and organise the relevant evidence

Submit the filled in form by email to one of the RPL Assessors below. They will then contact you back to organise an assessment interview. This interview may include presenting your evidence, answering knowledge questions and if necessary, further assistance to guide you to a sucessful result..

contact the Administration Office to obtain an enrolment form. Pay the RPL fees at the Enrolment Centre.
