The Royal Meteorological Society Professional Accreditation

Chartered Meteorologist (CMet)

Chartered Meteorologist (CMet) is the highest level of professional recognition in meteorology available in UK, no matter which discipline or sector you work in. It is well-respected for reaching and maintaining an outstanding level of professional performance and scientific knowledge, with a specialist area of meteorology.

Accreditation as a Chartered Meteorologist (CMet) will assure clients and employers that the individual has reached, and continues to maintain, a high level of competence in their specialist areas of meteorology and has agreed to subscribe to a code of conduct laid down by the Society.

The scheme is relevant to all professional meteorologists, whether consultants, academics or operational meteorologists.


All those working in the science, practice, application, advancement or teaching of meteorology can become accredited, subject to the appropriate combination of qualifications and experience.

A feature of the CMet scheme is that knowledge of meteorological science and practice can be demonstrated by extensive practical experience.

Those not meeting the standard requirements, but who might still be eligible to be accredited, are recommended to view the guidelines in further detail click here

Application Process

There are four stages when completing your first application, followed by a renewal every two years.

A tailored framework allows you to easily record developmental activities. You can gradually build on this throughout your career to demonstrate your commitment to professional development.

Step 1: Completing the application
You must complete the application process using ACCSYS. You need to be a member of the Society to access ACCSYS.

The main parts of the application are recording your CPD activities, writing an appraisal of your career, and providing evidence for how you meet the 5 key competencies. A resume or CV may also be added. Compiling your CPD record can take time, but do not be put off by the first step – completing the remainder of application only takes a few hours.

Step 2: Society Evaluation
The Society will check your submission and will seek references from your nominated referees.

Step 3: Interview process
The Society will arrange for you to be interviewed by a panel of two assessors. This is not an exam – it’s more of a stimulating peer to peer discussion, that will last about an hour. The interview provides you with the opportunity to demonstrate that you to the panel that you:

  • have a good level of specialist knowledge
  • have a broad knowledge of the current national and international context in which meteorological services are provided
  • meet the competency requirements.

Step 4: Decision
Following the interview, your application will be considered and decided by the Accreditation Board. On becoming a fully accredited meteorologist you will be issued a certificate, and will be eligible to use the post-nominals CMet after your name.

In general, the accreditation process takes approximately 4 months from receipt of your application to receiving confirmation of successfully completing the process.

Every two years your CPD will need to be renewed. Keeping your CPD record up-to-date during that time will make it easy to generate a report at the time of renewal. You can do this using our ACCSYS tool or simply keep detailed records yourself. The Society will contact you to request that you submit a CPD Report and the Accreditation Panel will review it. Once approved, you can continuing practising as a CMet.

Frequently Asked Questions

The application fee for CMet is £202.00.

There is an annual renewal fee for CMet of £50.00. You must be a member of the Royal Meteorological Society to apply, so these fees are in addition to membership.


To remain accredited, the renewal fee is due on an annual basis. You will also need to agree to the code of conduct annually, which can be done at the same time as fee payment. In terms of updating your record, CPD reports are required every 2 years.


The Council of the Royal Meteorological Society oversees the accreditation scheme and appoints an Accreditation Board (made up of at least 8 members) to manage it. The Accreditation Board is responsible for recommending acceptance or rejection of an application.


If you take a career break (e.g. for parental leave or other reasons) for more than six months, you may apply to be placed upon the CMet Dormancy Register. During this period, you maintain a reduced CPD record to show that you are keeping up to date in your field and expect within five years to submit this record to the Society to be reinstated as an CMet. During this period, your annual renewal payment is reduced but you cannot use the post-nominal CMet.



A full list of specialisms recognised by the Society can be found in the resources section on the CPD page.
