Joining IDEFFIE is easy : all that is needed is to share our desire to share and raise awareness of the French and French-speaking know-how in public policy expertise in order to contribute to the Sustainable development goals according to the francophone’s vision.

In order to have a better understanding of our approach, we invite you to read our charter.

From there, if you wish to take part in our actions as a physical person, whether you are a public or a private international expert, an academic or a researcher, an economist or a lawyer, a consultant or a civil servant, that you wish to take part in a working group, or that you simply want to support us, you can download the membership form and send it back to the address indicated on it, with a 30€ or a 10 € paycheck representing your annual membership fee, according to the conditions described on the membership form. The board will go through your application and will let you know about its decision as soon as possible.

For confidentiality reasons, we do not publish or distribute the list of our members.

If you are a private company, use rather the « private legal entities » form. If you are representing a public administration, use rather the « public legal entities » form. Finally, if you are a non-gouvernemental organization, use rather the « association » form.

In any case, if you experience a problem in your registration process, contact us at the following address: contact (at)

We look forward to see you among us!
