I often wonder about this. I'm a primary school teacher who has taught multiple classes now that included multiple children with SEN. The parents of the classes I've taught have no idea how much their children's education has been disrupted.
For example, instead of teaching the children, I'm regularly having to restrain or carry children from the classroom to stop them assaulting other children (yes, other children do get assaulted sometimes and we have to keep it on the downlow as much as possible).
During lessons, a child will be sat there swearing or shouting out rude/silly words, just trying to get a reaction. Other days, a child might be running around the classroom laughing their head off for the whole lesson. Or banging something against the wall while I try to give the input. Or climbing on high windowsills in the classroom. Or trying to kick other children. Or sticking their hand down their pants and then putting it in other children's faces. I really could go on and on.
I spend so so so much time dealing with this incidents instead of teaching and helping other children. Every day.
Basically, these children are not receiving suitable provision for their needs. They are not in the right place. It is chaos.
Parents, do you know this is going on in your child's school? Do you really not mind?
