The transition from school to employment is one of the great challenges for people with intellectual disabilities, after their inclusion in the educational system has been achieved. Takin in consideration that social inclusion often involves access to employment, the need to implement innovative methodologies that facilitate this process is key to its success. In line with the social interpretation of disability and the UN Convention, innovation in the training model must be applied to all the actors, with special emphasis on achieving an inclusive environment. We present some results of the Individualised Itineraries Programme developed in Castilla y León (Spain) in which public-private collaboration configures a comprehensive, flexible and individualised project that accompanies them in their transition from school to employment. As a result, their professional profile is improved and their labour competences are increased, guaranteeing their participation in the process.
