Since year 6 (although I'm guessing it's happened since the start of school) has been shouting out in class. This can be because she knows the answer to a question or it could be that she hasn't understood something and needs clarification. This has been raised by different teachers several but nothing seems to stop her doing it. We've spoken to her about t not being acceptable and she says she just doesn't know why she does it as it just sort of happens before she thinks about it.
She's now 14 and enough is enough. Any ideas how we should tackle this. We've never actually spoken to anyone at secondary school. I have wondered if it might be "medical" rather than naughty but not got beyond that.
