To be autistic is to live in an incomprehensible, unpredictable and chaotic world. RESALIANCE is a cross-border platform designed to support people with autism spectrum disorders and raise awareness of their environment in order to spread a concrete, positive and innovative approach throughout the cross-border territory. The challenge for the partners is to create an innovative system on the cross-border territory to provide autistic people, their families and their environment with new tools and methods that improve their quality of life and promote greater social goodwill. The project is based on three keys: the understanding key, the behaviour key and the transmission key. Each key is adapted to the person with autism (target group), the first circle (caregivers), and the second circle (environment). The stated ambition is to facilitate access to services and promote the complementarity of skills to create a sustainable system that will change the lives of people with autism and their families.
