COST is streamlining its proposal submission, evaluation, selection and approval (SESA) procedure. We look forward to receiving your proposals, which you’ll be able to submit in Summer 2026 with a submission deadline of Autumn 2026.
In Open Call 2026 up to 70 COST Actions will be funded.
All relevant documents will be available in Spring 2026. This page will be updated as soon as more information is available.
Participants are invited to submit COST Action proposals contributing to the scientific, technological, economic, cultural or societal knowledge advancement and development of Europe. Multi- and interdisciplinary proposals are encouraged.
The Open Call Action proposal submission, evaluation, selection and approval (SESA) procedure is fully science and technology-driven and will ensure a simple, transparent and competitive proposal evaluation and selection process, reflecting the bottom-up, open and inclusive principles of COST.
Participants planning to submit a proposal for a COST Action will need to refer to the COST Open Call proposers guidelines and to the Open Call Announcement that will be available on the Documents and Guidelines page in Spring 2026.
All proposals are to be submitted via the dedicated online platform of the COST Association used for grant management, known as e-COST.
For general questions related to the Open Call please contact your COST National Coordinator who will be able to assist. More technical questions can be addressed to opencall@cost.eu
