I don't envy teachers and the incredibly difficult situations they find themselves in. A lot comes down to poor communication, and not having the tools to do their jobs efficiently, and keep the class under control. It does seem that the children have more rights than the teachers, especially when it comes to discipline. In many cases it is easier to diagnose a learning problem than to actually face up to not being able to keep control of the class, and the pupils therein. The school system tends to turn teachers into robots, and if a child misbehaves and doesn't keep up then too bad, that child will just fall behind and be diagnosed with a learning problem and be passed on to someone else to deal with.

My sister was a teacher in England until she kept an unruly class in at recess to complete the lesson. She was reprimanded by the headmaster because she was taking away the children's rights to have a recess break. She quit on that day and now has and office job, not using her teaching degree (with honours in psychology) at all.

Hopefully you and the school can land on the same page and come to a suitable plan to help get things back on track, and well done for having the courage to confront the school head-on about it. That lets Jude know you've got his back at school too! Great parenting!
