Chartership Assessors

Our experienced Chartered Fellows, who uphold professional standards across a broad spectrum of Earth science disciplines, support the Society’s Chartership process as volunteers, assessing and advising Chartership applicants.

We are always looking for new Assessors to join our panel, and also invite Assessors from overseas to ensure we find appropriate matches for our different applicants. Our interviews are mostly carried out online, and are now worldwide.

There are many areas of geoscience that would benefit from more Assessors such as renewable energy and the energy transition, mining, and academia. Earth science is becoming increasingly regulated as a profession so if you are working within these industries, we would especially welcome you to the panel.

By volunteering with the Geological Society, I have been able to raise my professional profile and contribute to a range of important initiatives to support the geosciences in the UK and further afield”

By becoming a Chartership Assessor, you are taking another step in your own professional journey. Here are some of the benefits:

  • Give back to the Earth sciences community;
  • Demonstrate your seniority;
  • Contribute to your CPD record to maintain Chartered status by reviewing applications;
  • Expand your knowledge of the innovative work emerging throughout the sector;
  • Gain valuable interview experience; and
  • Enjoy networking opportunities with other experienced professionals.

An additional Assessor benefit is access to any online Geolsoc Training Course at a highly discounted rate. This rate is 75% off the full fee (or 50% of the advertised Fellows rate).

The benefit can be used once per year. This could be for one multi-part course, or for one single module, or for one-day/part-day course. Almost all our courses are online so a wide range of topics is available to you. All registered Assessors who undertake a Chartership volunteer role within the same calendar year are eligible. This role could be a Chartership application review, a defer review, taking part in the CPD audit or in the Chartership audit. Please contact us to take up the offer.

We are excited to be able to share this benefit with you from 2024, and thank you for your hard work in supporting the Chartership application and review process.

Chartered Fellows with over five years’ experience post-Chartership, or with a considerable number of years’ experience pre Chartership, are encouraged to apply to join the panel.

To apply, you must be a current Society Fellow and have held CGeol or CSci status for at least 5 years (but fewer for those very experienced prior to gaining Chartership).

Training is provided, including regular workshops with other Assessors. Details are available from the Chartership Officer.

Apply using the online application form below. You will need to include a short CV and your latest 3-year CPD record.

Chartership application deadlines are four times a year and the Chartership Officer assigns the Assessors in pairs to each candidate. Assessors review the application documents and make their decision to proceed to interview stage.

The validation interviews are generally carried out online, and the Assessors pass their recommendation to the Professional and Chartership Committee via the Chartership Officer.

If you have any questions please contact the Chartership Officer

Guidance documents about being a Chartership Assessor are below.

We hold Chartership Assessor training events, in which we provide updates and guidance to our registered Assessors on the application review process, and give the opportunity for Assessors to convene to:

  • share their review experiences;
  • discuss benchmark standards for Chartership within their areas of expertise;
  • highlight best practices and great examples; and
  • exchange ideas on review and interview approaches.

Our next in-person Chartership Assessor training event will take place on 9 July 2024 in Bath. Find out more here.
