Use of Designatory Letters

Designatory Letters are often used within a work environment. They demonstrate that you have achieved a certain qualification level or that you are a member of a professional organisation.
Designatory letters issued by professional organisations are normally preceded by the letter A (associate), M (member) or F (fellow). This normally highlights the level of experience and qualifications of the member.
We have tried to make our list as extensive as possible, but some qualifications and professional organisations may have been omitted.
