Probation is a non-custodial measure involving the monitoring and supervision of a child whilst he or she remains in the community. A competent authority, the public prosecutor, the social welfare service or a probation officer usually supervises probation. Probation may be employed as a measure on its own, or following a custodial sentence. During probation, the young person must maintain good behaviour, not commit another offence, and meet any other conditions the court may deem appropriate to impose.
