Already Chartered?

The award of Chartered Geologist or Chartered Scientist acknowledges that you have reached an important professional milestone. Chartered status is a symbol of technical competence and signifies a public commitment to professional standards.

As a Chartered Geologist or Chartered Scientist you can:

  • Use the post-nominal letters CGeol or CSci
  • Use the CGeol or CSci logo in your e-signature - CGeol ink-stamps can also be ordered; and
  • Be listed in the online register of Chartered Fellows

In order to retain your status as a Chartered Geologist or Chartered Scientist you must:

  • Remain a paid-up Fellow of the Geological Society
  • Abide by the Society’s Code of Conduct; and
  • Continue to maintain your CPD records – each year you will be asked to affirm this action and a percentage of Chartered Fellows will have their personal development record audited.

Please keep the Society updated with changes to your contact details as we may be obliged to withdraw your Chartered status if we are unable to contact you, e.g. to notify of outstanding subscription fees.

For several years, the Geological Society has been seeking to conclude agreements with a number of overseas professional organisations under which we would mutually recognise the equivalence of each other’s professional qualification (‘title’). Such agreements have been in place for some time with the American Association of Petroleum Geologists and with the Institute of Geologists of Ireland, and in 2012 this agreement now includes the American Institute of Professional Geologists.

Discussions are continuing with Geoscientists Canada to explore the scope for establishing a mutual recognition agreement covering all the Canadian jurisdictions. 


Reciprocal arrangement with the American Association of Petroleum Geologists (AAPG)

AAPG logoThe Geological Society has agreed a reciprocal arrangement with AAPG whereby Chartered Geologists can apply for certification with AAPG, and vice versa, via simplified application procedures. AAPG members who wish to apply for Chartered Geologist status must be Fellows of the Geological Society and conversely applicants for certification with AAPG must be Members of AAPG (see www.aapg.org for information).

Chartered Geologists who wish to apply for Certified Petroleum Geologist, Certified Petroleum Geophysicist or Certified Coal Geologist status with the AAPG should download the documentation and:

Applicants should send the completed application form with the annual certification dues to the Fellowship Department, Geological Society, Burlington House, Piccadilly, London, W1J 0BG. We will then sign the form to certify that you are a Chartered Geologist and forward it with the payment to AAPG.

Certified members of AAPG who wish to apply to be Chartered Geologists with the Geological Society should download the documentation and:

Applicants should send the completed application form with the application fee to:

The Division of Professional Affairs
American Association of Petroleum Geologists
PO Box 979
Tulsa, OK74101-0979
USA

The AAPG will then certify the form and forward it to us.


Reciprocal arrangement with the American Institute of Professional Geologists (AIPG)

AIPG logoLate last year, the Society concluded an agreement with the American Institute of Professional Geologists (AIPG) following a review that established that the aims and objectives of both organisations, and the peer review processes, although they differ in detail are equally exacting and broadly comparable. As a result the two organisations have agreed to recognise the equivalence of the titles of Chartered Geologist (CGeol) and Certified Professional Geologist (CPG). For further details, read the mutual recognition agreement.

Chartered Geologists who wish to apply for Certified Professional Geologist (CPG) with the AIPG read the By Laws and Code of Ethics of the American Institute of Professional Geologists (AIPG), which must be followed by all Certified Professional Geologists with the AIPG before completing the application form.

After completion of this form please return it to The Fellowship Office of The Geological Society, Burlington House, Piccadilly, London W1J 0BG for confirmation that you are a Chartered Geologist in good standing with the Geological Society of London. The Geological Society of London will then forward the completed form to the AIPG.

Professional Members of the AIPG who wish to become Chartered Geologists should read the Geological Society's Code of Conduct before completing the application form.

After completion of this form please return it to: American Institute of Professional Geologists, 12000 Washington St., Suite 285, Thornton, Colorado 80241 USA for confirmation that you are a Certified Professional Geologist member in good standing with the AIPG. The AIPG will then forward the form to the Geological Society of London.


Reciprocal arrangement with the Institute of Geologists of Ireland (IGI)

IOG logoThe Geological Society has agreed a reciprocal arrangement with the IGI whereby Chartered Geologists can apply to be Professional Members (PGeo) of the IGI, and vice versa, simply by writing to the organisation with which they require professional certification.

This organisation will then check that the applicant holds the necessary qualification with the other organisation. Successful applicants will be required to pay the relevant annual fees of both organisations. For more information about the IGI see www.igi.ie.

IGI Professional Members who wish to apply for Chartered Geologist status must be Fellows of the Geological Society. There is no application fee for Professional Members of IGI to become Chartered Geologists, but if they first need to apply for Fellowship, they will need to pay the Fellowship application fee.

Institute of Geologists of Ireland
UCD School of Geological Sciences
