There are two modalities of participation in a COST Action:
Working Group (WG) participation (long-term participation):
- Participation as WG member is open to any individual affiliated in a legal entity wherever in the world, except in cases of Incompatibilities as per Article 4.2 of the COST Action Rules.
- Participation as WG member implys a duty to contribute to the realisation of the objectives of the WG and gives rights of access to activities and information shared in the Action.
- Participation as WG member is reflected on the COST website for visibility purposes.
- Participating in a COST Action is bound by the COST Principles (level A) and the COST Action Rules (level B) as complemented by the Annotated Rules (level C).
Applications to become a WG member shall be submitted via the Action page on the COST website.
The Action MC (or the delegated group) review the WG membership applications on a regular basis. The maximum delay between application and decision not exceed 3 months.
Ad-hoc participation (short-term participation):
Participation to a COST Action may also take the form of an ad-hoc participation, subject to invitation by the Action MC during the lifetime of the Action. Incompatibilities as per Article 4.2 of the COST Action Rules shall also apply to ad-hoc participation.
