Participation in Garda youth diversion projects is voluntary. The primary project target group, which forms the majority of project participants, comprises young people who have entered the Garda juvenile diversion programme and are considered at risk of remaining within the justice system. The secondary project target group comprises young people who, although they have not been officially cautioned, have come to the attention of the Garda, the community or local agencies as a result of their behaviour and are considered at risk of entering the justice system at a future date. The number of participants in each project differs according to local circumstances and resources. The focus is on the quality of the work-intervention with the participants rather than on the quantity of participants.
