RMet CMet Comparison

The Society offers two professional accreditation schemes:

These schemes are hierarchical statements of professional competency and experience and are consistent in concept and scope with similar accreditations recognised in other professions. The Royal Meteorological Society is the only body able to award Registered or Chartered status for Meteorologists. The schemes are progressive and typically new entrants to the profession might aspire to Registered Meteorologist and then progress to Chartered Meteorologist at a later stage. However, there is provision for those who meet the criteria to apply directly for Chartered Meteorologist.

The schemes enable individuals to demonstrate professional competence based on their knowledge and expertise, have a professional qualification that is recognised by major employers in UK and the European Union, and show a commitment to professional development by recording developmental activities in a tailored framework.

A Brief Guide to the Requirements of RMet and CMet

The two schemes differ in the requirements for scientific background, knowledge and practice and experience but both require probity and the ability to communicate clearly in English

Below is a comparison chart, showing the differences in requirements between the two schemes


Registered Meteorologist

Chartered Meteorologist

Scientific background

The normal requirement is a fundamental knowledge in the subjects of physics, chemistry, mathematics or geography to minimum university entrance qualification level.

The normal requirement is a degree (or equivalent qualification) in any science, engineering or computational subject. An alternative qualification may be accepted in the case of someone with considerable relevant practical experience.


In either case, lower qualifications together with extensive practical experience may be an alternative.

Knowledge of meteorological science and practice

Material set out in the WMO BIP-MT syllabus§ or, for example, that covered by the QCF Level 5 Diploma in Weather Forecasting (or equivalent).

Material is set out in the WMO BIP-M syllabus§ and would normally be provided by specialist university courses at first degree or higher degree level in meteorology, or equivalent professional training.


Registered Meteorologist

Chartered Meteorologist

Experience and judgement

Depends on vocational qualifications but it is likely that around three years experience of work as a meteorologist, or supporting meteorological services, will  be necessary to demonstrate the required competencies.

A minimum of five years recent work at an appropriate professional level is normally required.

Competence, including an ability to communicate clearly in English

A Professional Review provides evidence of the extent to which the RMet competencies are satisfied.
Evidence of the ability to communicate effectively and accurately in English, both orally and in writing, is required.

At present CMet competencies have not been defined so a Professional Review is not required.
Evidence of the ability to communicate effectively and accurately in English, both orally and in writing, is required.

Probity and willingness to abide by the code of conduct

Referees will be expected to vouch for the character and honesty of applicants
Registered and Chartered Meteorologists of the Royal Meteorological Society are expected to abide by a Code of Conduct in addition to the Society’s Code of Ethics.




Maintenance of professional currency

Registered and Chartered Meteorologists are required to maintain and develop their knowledge and skills, keeping up with the advances in the subject in general and their specialist area(s) in particular, and to steadily improve their experience and capability.
