@aros as seen on the guideline:
Non ICT Diploma or Higher
If your qualification is assessed as AQF Diploma or higher and with insufficient ICT content, you will require 6 years relevant work experience completed anytime in your past work history, plus a suitable Recognition of Prior Learning (RPL) application to meet the suitability criteria.
So a minimum of 6 years will be required for you to have a suitable assessment:
4 – Recognition of Prior Learning – (RPL)
The RPL application is for applicants with qualifications with no or insufficient ICT, or applicants having no tertiary qualifications.
<b>6 years</b> of full time professional ICT work experience in a field closely related to the nominated ANZSCO Code is required if you hold a Non ICT or insufficient ICT qualification and 8 years if you do not have any qualifications.
You are required to submit <b>2 Project Reports</b> within an RPL application - ACS Recognition of Prior Learning Form.
