South Australia Juvenile Justice (SAJJ) Project on Conferencing
The focus of the SAJJ project was on ways of measuring (1) restorative justice practices and (2) variability in the conference process and participants' understandings of it. While many people assume that a "successful" conference will have positive future effects, the SAJJ project treated this as an open question. http://www.aic.gov.au/criminal_justice_system/rjustice/sajj.aspx
