In the future, organisations' ability to consider the different aspects of equality of people will become a competitive advantage. Diversity of people as a concept refers to such differences as e.g. age, sex, disabilities and ethnic & cultural background, which means that it influences everybody in many work-related circumstances. This project will respond to questions on diversity at workplace through further developing trainers’ and workplace instructors’ skills and competences in this issue. First an assessment tool will be developed to make qualification analyses and to collect information of the competence that trainers and workplace instructors need in the field of diversity of people.
