You will need to keep your professional development records current after graduation to maintain your registration. An ePortfolio is an excellent way to keep these documents together and assemble them in one submission for re-accreditation. It also allows you to progress your career by reflecting on your current practices and developing your skills in conversation with your peers.
For Health Professionals the Australian Health Professionals Regulation Authority (AHPRA - https://www.ahpra.gov.au/) produces registration standards for disciplines such as Nursing & Midwifery, Physiotherapy, Occupational Therapy and Psychology.
Teachers likewise require accreditation and the Australian Institute for Teaching and School Leadership (AITSL - https://www.aitsl.edu.au/) provides a Nationally consistent registration that requires multiple sources of evidence against the Australian Professional Standards for Teachers.
These Standards progress through Graduate, Proficient, Highly Accomplished, to Lead; you will need to gather evidence against these standards to move through each level of your teaching career.
