In Europe we can see that mobility is increasing, and the result is we can have in the same place (work, classes, home), at same time, very diverse people: gender, age, race, social class, religion, culture, and so on. It is necessary to know how to deal and make the most of this diversity. The trainers and teachers of adults are considered agents of policy and change since they can reach and work new skills in many people, in effective way. The new role of adult educator as facilitator of learning includes the management of diversity, as well as ICT and research skills which needs to be developed in many European countries, according to Eurotrainer report (Jan 2008). So a course on diversity management is necessary. A previous EQUAL project concluded that the skills the trainers need to develop diversity management can be enhanced transversally through 7 pedagogical key activities: diagnosis, pedagogical resources, language, pedagogical relationship, leadership, self-questioning, and formative assessment. The course will be build according to constructivist model, to ensure the appropriation of the new skills: the learners will engage in research on new Adult Educator role, will work in teams to elaborate a project. The course will be blended so learners can develop ICT skills and learn at their own pace. The course learning package includes a self-assessment system, project guide, tutorial program and course manual, all available on CD-Rom in all partners’ languages. To build this course the partnership will have research on the subject, production of learning package and CD-Rom, pilot course on 4 countries, validation of final products. Once learners incorporate the diversity management skills, they will act accordingly whenever they are trainers or teachers, hence replicating and inducing these skills to their learners, who in turn can pass on the skills to co-workers and families; and an adult educator reaches dozens of learners per year, minimum; great impact.
