The document discusses revalidation in the Australian context, noting that mandatory continuing professional development (CPD) has been in place since 2010 but varies by field of practice. It outlines the Medical Board of Australia's progress, including commissioning research on options and community expectations and establishing expert advisory groups. Pilot models of revalidation will be tested from 2016-2017 before potential adoption and implementation in 2017-2018. Key challenges for Australia include that legislation currently mandates CPD not revalidation, determining the purpose of revalidation, and deciding on universal or risk-based approaches while considering feasibility, acceptability and cost.
