That's interesting twinset - I didn't know that!
Umlellala - the school my DS was at was just too overwhelming for him. It was a Junior with 400+ DC's, who all had playtime/luchtime at the same time which DS found very difficult to cope with. It was suposidly a "good" school in a nice area. When he trasfered to the school he was tested to see which groups he should be in, and as he was so over whelmed he didn't write much in the test, and was subsequently put in low groups for English and maths.(I have no ide why they paid no attention to his Y2 sats, but I think it was becuase so many children going into the school had scored level 3)
Because he wasn't being cared for apropriately, or educated aproprately at school he started to school refuse. There were also a few insidents where he was injured on the playgound (one incident involved him comming home covered in bruises as 6 children had had him on the floor and kicked him).Because of this he became extemely defensive - and willing to fight anybody who seemed at all threatening. This was totaly out of character for him - he had been the sweetest child imaginable at nursery/infant school - much prefering to play with girls than boys.
One day, after weeks of school refusal, I begged him to go into school (basicaly becuase I needed child care that day )During the morning he was so unhappy he ran out of school, but found him self on the street, far from home, not knowing what to do, so he went back onto the school field. (This was during break time) Members of staff were aware he had run out, and come back, and asked him to come into the school building, which he refused to do. The head was called to deal with him,and took him by the arm, and asked him to come into school, to which DS said "If you don't let go of my I will kick you in the testicles" .Needless to say the head let go pdq. Two TA's then picked DS up and carried him into the school.DS struggled, and in the struggle one of the TA's was hit on the side of her face.
DS was excluded for the rest of the term (thank God!) - and never returned to that shchool. The head told us the only reason DS was not permanently excluded was that he (the head) was a Christian.
The head had already decided DS was Autistic by the way, but had done nothing to help us get a DX.
So I would argue it is not always the case of parents not taking their job seiously - but can be the schools not doing their job effectively which result in exclusions.
