Skill recognition

Recognition of Prior Learning (RPL)

RPL is the acknowledgement of a person's skills and knowledge acquired through previous training, work or life experience, which may be used to grant status or credit in a subject regardless of how and where they were attained, including overseas.

This can include skills from:

  • Previous study excluding courses at another VET/TAFE institution, but including courses at school or college, through adult education classes or training programs at work;
  • Work experience (including both work that is paid and unpaid); and/or
  • Life experience (for example leisure pursuits or voluntary work).

RPL is a form of assessment. It is used to determine whether a person has acquired, through formal or informal learning, the skills and experience consistent with the stated competency standards that comprise a qualification. RPL is not time referenced, so there are no parameters on how or when the skills are acquired. However, the skills that have been acquired through life experience etc., must be current and must match the elements and performance criteria contained in the individual unit.

Students seeking RPL need to indicate this on their enrolment form at the time of enrolment.

For further information please refer to the Applicant's Guide to the Recognition of Prior Learning or contact Student Central on 1800 061 963 (free call) or email
