The frequency is established during what is called “pre-release”, and is confirmed during the first meeting with the offender.
Again, I can't speak to that specific case, but I can explain that there are several levels of contact frequencies. There's the intensive level, where the offender has to be seen face-to-face eight times a month. There are also levels A, B and C, where the offender must be seen either two or four times a month. All of this is based on the risk the offender presents and the offender's needs.
The level of intervention can be reviewed at certain times, once there has been some stability in the community. A case conference is then held between the parole officer and the supervisor.
