Reformatory school doesn't sound like the right solution if he isn't cutting class, causing trouble, or displaying serious behavioral problems. However, if he has been evaluated twice for making suicidal comments to a counselor and is having so many problems with being bullied that he doesn't want to be at school, it may be worthwhile for you to consider other school options for him to demonstrate that you're actively dealing with his issues rather than disregarding them. Maybe not reformatory and not the current situation, but something else that would be more beneficial.
