Membership wizard: Professional membership

Those with statistical qualifications may be eligible for one of our professional membership categories. Our professional membership categories bring exclusive benefits designed to support professional and career development.

Graduate Statistician (GradStat) provides formal recognition of a member’s statistical qualifications. We encourage GradStat members to undertake suitable professional training and experience, normally for at least five years, that will enable them to apply for Chartered Statistician (CStat) status. Please visit the dedicated landing page to read more information on eligibility. 

Chartered Statistician (CStat) is our highest professional award. It provides formal recognition of a member’s statistical qualifications and professional training and experience. Our CStat award is a respected designation and has many benefits for professionally active statisticians. Please visit the dedicated page to read more information on eligibility. 

CStat members can also apply for Chartered Scientist status.

Please bear in mind that in order to hold professional membership status you will also need to be a fellow of the Society; so it is almost certainly worth joining as a fellow before you make an application for CStat or GradStat. Fellowship will support your statistical interest and you can join straight away. If you are accepted for professional membership you will only need to pay a small top-up fee to become registered if you are already a fellow.

Applications for professional membership can take a few months to be processed as we will need to verify all your information and submit your case to the Professional Affairs Committee. You can start an application at any time, and it can be completed in stages through our dedicated website which also includes full notes for guidance. If you would like to discuss any aspect of professional membership or query your eligibility please contact the Professional Affairs Manager, Sarah Barker ( who will be happy to help you.
