DD has ASD diagnosis, well known to school - mainly anxiety and social issues, though most of the time she copes very well and has a lovely best friend who supports her. On Friday her class were asked to write a letter about themselves to their new Y6 teacher. Teacher then read out a small part of DD's letter (according to DD, they weren't told she would do this before writing) about her dream of where she'd like to live in future - cottage in the woods - and the class laughed at this. DD was very upset when telling me, saying that people had laughed at her and that nobody understands her/she doesn't fit in. Best friend was out of the room at the time. Teacher didn't read out anyone else's letters but apparently also revealed that a boy in the class had watched Frozen, saying 'oops, shouldn't I have said that?'; according to DD, the class also laughed at this and this boy looked embarrassed. Am I being unreasonable to feel that this teacher's behaviour was out of order? - she basically singled out a couple of children to make the others laugh at them (no idea why, other than to gain popularity with the rest of the class?) And particularly that she should have known better than to do this with a child with SEND? What would you do?
