Adult education can be a key for transformation, challenging unjust power structures, enabling participation and overcoming marginalization. OED Methodological Guidelines aim to support managers, course designers and practitioners in adult education institutions in their work with socially and educationally disadvantaged groups. The Guidelines are based on examples of good practice collected from 14 European countries. They reflect the experiences of adult educators working in the field.
