I think that frankly you either had a problem thinking of ways to categorise the separate facilities, or you're trying to be provocative.
Trying not list all the possibles and only listing the extremes.
Exclusion,
Seclusion units within the school and away from the mainstream.
Finland has what is considered the best education system in Europe at present, primarily because there is a resident social worker in each school to deal with the problems as there arise.
The industry: things like Incident of concern report,Serious Incident Report, SENSS, PSP, SENCO, IEP action plus, TOCH, Pupil referral form, CSEP, Pacemakers Mentoring scheme.. and the others....
My previous were a broad view, if you would like a detailed synopsis... well. that would take some time.
The reluctance of parents to participate in schemes designed to help their children. The past record of pupils after managed moves and the re-ocurrence of basic incidents, all contribute to the title of ' the excluded pupil'
I can understand the the concern if you have particpated in a 'Span' unit but.... I have a report in front of me detailing how this pupil has .. ' arrived on time, enthusiastic and keen to seek and grasp the variety of lessons and tools in order to enhance general life progression. Has actively participated within the structure of the organisation in general and has been a pleasure to work with.... during the session it has been an objective to relate ' lessons learnt' back into the school environment context at every opportunity..
Wow, you would think after a report like that the pupil would settle and change into a glowing and praise worthy individual.... actually, he pulled a knife on another pupil and was permantly excluded...
His file is something like 180 pages, my concern is the cost where early intervention might , only might, have changed the outcome, but the system does not allow for a quick and realistic response to incidents. The weekly meeting, HOY, HOD's subject teachers all have input and measures to implement, The paperwork, the people involved, the outside agencies when a selusion unit within the school and away from the mainestream classroom would help addressthe problems.
