Three organisations joined together to propose a Diversity Charter. In a first phase, diversity within the different signatories will be monitored. To simplify the task of monitoring for all partners involved, a survey has been made available to be filled out on a voluntary and anonymous basis by affiliated people and participants to the signatories.
