The Office of Professional Affairs of the RCPSC is responsible for a mandatory maintenance of certification (MOC) program as part of its strategy of continuous professional development linked to each Fellow’s professional practice. The framework of CPD options includes a broad spectrum of learning activities linked to a credit system. All Fellows submit their completed learning activities through MAINPORT, the RCPSC learning portfolio. Fellows of the RCPSC must submit a minimum number of credits per year (40 credits) and over a 5-year cycle (400 credits) to maintain their membership with the Royal College and their right to use the designation FRCPC or FRCSC.
