European judicial training represents a substantial tool in the process of building the European area of justice. Lawyers, prosecutors, and judges must have a good knowledge  of the EU acquis and its cooperation instruments, as well as an appropriate understanding and mutual trust in the different national systems. Judicial training represents a key tool for building such mutual trust and cooperation in order to protect victims of human trafficking, both European and foreign citizens, and to have an active contribution in the fight against the phenomenon. The purpose of this publication is to present in detail the way in which trainers and organisers can prepare a judicial training on such topics - from pre-training actions until the final evaluation to assess the events’ impact upon the target groups. The publication was elaborated within the framework of the initiative Training lawyers, prosecutors, judges to ensure better rights protection for migrants and refugees victims of human trafficking implemented by human rights and research organisations from five EU Member States with the participation of the Center for the Study of Democracy.
