At the annual meeting of the General Assembly on 29 November 2018, the institutions of the Leibniz Association approved a revised version of the Guidelines for Good Scientific Practice that had been adopted three years earlier. The binding guidelines set standards of good scientific practice for the institutions, define misconduct and describe the role and authority of the association’s central ombudsperson. They also include a code of practice and the sanctions available within the central investigation process. The Leibniz institutions manage their procedures in accordance with the guidelines. Leibniz Headquarters supports and promotes inter-institutional networking activities on this topic.
