Chartered Scientist (CSci) is a professional qualification in the United Kingdom that is awarded by the Science Council through its Licensed member organisations. Holders of this qualification can use the post-nominal letters CSci.
Chartered scientists are professional scientists who are practising and/or advancing science at the full professional level and are individuals for whom scientific knowledge or practice at that level form an essential element of their role. Chartered scientists are characterised by their ability to deal with complex issues, both systematically and creatively and can make sound judgements in the absence of complete data to develop solutions to scientific problems and communicate their conclusions clearly to specialist and non-specialist audiences.
The required standard[1] for Chartered Scientist registration is a Masters-level science qualification (or equivalent) with four years of postgraduate work experience.
