when ant was in isolation, hearings were held on the same day each week for all prisoners who had infractions of the rules. perhaps your son already signed a paper admitting to what he had done and then the hearing would be just paperwork with him not present.
as for the evaluation and the waiting list...the evaluation can take months to get scheduled depending on whether or not they have a psychologist on duty, how long the wait list is, and how severe the problems are of the people ahead of him in line.
