This manual is the result of a long process to identify and promote the use of global juvenile justice indicators. This work was initiated at UNICEF, and has been led since its inception by Alexandra Yuster. Jan Baaroy provided early technical support. An expert reference group worked over a period of 6 months to select the final indicators. Members were Professor Jaap Doek, Chair, Committee on the Rights of the Child, Paulo David and Joel Mermet, OHCHR; Eléonore Morel, Penal Reform International; Ann Skelton, Centre for Child Law, South Africa; Willie McCarney, International Association of Family and Youth Judges and Magistrates; Hans Schueler-Springorum, University of Munich, Séverine Jacomy, OMCT; Professor Sedfrey Candelaria, Ateneo Human Rights Center; Ray Dean Salvosa of Consuelo Foundation; Geert Cappelaere, UNICEF and Nigel Cantwell, independent consultant.
