BACKGROUND:
In response to the growing need to integrate experiential knowledge into evidence-based health promotion, a national multi-professional working group was formed in France since 2016. Led by Fédération Promotion Santé and the Société Française de Santé Publique, this initiative brought together field actors, researchers, and institutional representatives from diverse organizations and contexts.

METHODS:
The group was established to co-develop the Capitalisation of Experience Knowledge in Health Promotion (CEKHP) approach. Its creation involved a participatory process: literature review, benchmarking of existing capitalization methods, and iterative testing and refinement of tools. Regular exchanges and training sessions fostered a shared understanding and commitment among members, ensuring the approach reflected both academic rigor and practical needs.

RESULTS:
The collaborative dynamic enabled the design of a structured, five-step capitalization process, supported by dedicated tools and a community of practice. The group’s diversity—spanning research, practice, and policy—enriched the development of CEKHP, which now serves as a bridge between experiential and scientific knowledge. The inclusion of an external facilitator and a community of practice strengthened reflexivity and skill-sharing, empowering all stakeholders.

CONCLUSIONS:
The CEKHP initiative demonstrates the value of multi-stakeholder collaboration in health promotion. By uniting professionals around a common goal, it has created a sustainable framework for experiential knowledge production and transfer, enhancing the adaptability and scalability of health interventions.
