Chartership & Professional

Accreditation as a Chartered Geologist or Chartered Scientist is a sign to clients, regulators, employers and the general public that you are a competent professional who can demonstrate a high level of knowledge, skills and experience, and that you are bound by a strict code of professional conduct.  

The Geological Society of London is the recognised UK professional body for Geoscientists. It awards the professional title of Chartered Geologist (post nominal CGeol) and is licensed by the Science Council to award the title of Chartered Scientist (post nominal CSci). The Chartered ‘designation’ indicates a professional practitioner who has been peer assessed as having key professional competencies and experience in their field of practice. They are required to maintain their professional skills and knowledge through an appropriate programme of CPD and are bound by an enforceable Code of Conduct.

The Chartered Geologist title is appropriate for those fellows practicing as professional geoscientists and for whom geoscience knowledge and competency is an essential element for fulfilment of their role. The Chartered Scientist title is appropriate for Fellows practicing as professional scientists and for whom scientific knowledge and competency is essential for their role.

Both titles are of equal standing and many Fellows will fulfil the requirements for both CGeol and CSci.
