As opposed to all that had been said around that point I took the somewhat pragmatic view that 'Each case should be decided on individual merits.' Whereas it was unlikely that an 18 year old would have enough worldly experience for the task - I have met a few who would perhaps have been good enough, young as they were.
I have already considered an issue on this Blog of 'the cult of youth' where Council seats are concerned.
There may be the 'one case in a hundred' where youth should prevail in a given situation but experience is usually going to be key.
I am rather uncomfortable about the pressures on schools from OFSTED et al to have student councils which actually 'have teeth'. There seems to be a desire to put members of these onto interview panels for teaching posts!
This is completely undesirable and it is more than likely that inappropriate youths across the nation would have positions of power based on inexperience: influence without either experience or responsibility.
