The Royal Meteorological Society professional accreditation

What is the difference between CMet and RMet Accreditation?

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. The Society offers two professional accreditation schemes:

A Brief Guide to the Requirements of RMet and CMet

The two schemes differ in the requirements for scientific background, knowledge of meteorological science and practice, experience and competence, but both require the ability to communicate clearly in English, probity and a commitment to continued professional development.


Registered Meteorologist

Chartered Meteorologist

Scientific background

Knowledge in physics, chemistry, mathematics or geography up to university entrance level.

Degree in any science, engineering or computational subject. An alternative qualification may be acceptable for 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

Knowledge specified in the WMO BIP-MT syllabus*. This might be covered by the QCF Level 5 Diploma in Weather Forecasting (or equivalent) or equivalent professional training

Knowledge specified in the WMO BIP-M syllabus*. This would normally be provided by specialist university courses at first degree or higher degree level in meteorology, or equivalent professional training.

Experience and judgement

About three years practical experience in meteorological services, but the period depends upon the vocational qualifications.

Minimum of five years recent work at an appropriate professional level.

Competence, including an ability to communicate clearly in English

Evidence of RMet competencies covering application of knowledge and understanding, personal responsibility, interpersonal skills, professional practice and professional standards.

Communicating in English

Ability to communicate clearly in English in writing and orally.

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 meteorology in general and their specialist area(s) in particular.
