The present report precedes the development of the CHILDfront training materials and the capacity building endeavor involving judicial trainers. It aspires to present a solid background of what has already been achieved at the EU level and beyond and which an innovative and practice-oriented learning tool should step on. Together with the Training Needs Assessment Report, assessing the Greek and Cypriot professionals’ view on what can be improved at the national level, this report will assist in developing a modern set of training tools that respond to professionals’ real needs. In order to do so, it classifies the collection of practices into the following groups and analyses them: 1) training of trainers, 2) training of criminal justice professionals, 3) training of civil judges, 4) training of administrative judges and 5) training on the cross-cutting issues of child psychology and data protection. The finalsection summarises essential findings and draws recommendations to develop training tools. In addition, the report brings together a library of what has already been achieved in the area of child-friendly justice so that future efforts in the same area might easily refer to it.
