The "Operatori culturali per l'inclusione" project was created to train museum and cultural service staff in inclusive approaches, promoting culture as a heritage accessible to all. The initiative enhances relational skills and knowledge about disabilities, combining theoretical, workshop, and practical training. Follow-up research has highlighted a real change in attitudes and organizational processes, making structures more inclusive. The model, shared and replicable, confirms how inclusion and participation are inseparable from the quality of the cultural experience.
