Can I ask, does it seem like a weight lifted, to know you can trust her teacher.
TBH, I already trusted her. She seems like the kind of person who treats everyone as an individual, if you know what I mean. She is very good with my quirky, peculiar, clever, scaredy kid. But yes, it is lovely to know that DD has someone on her side who isn't just spouting the 'mastery' bollocks and recognises that if you've already achieved mastery as far as the primary curriculum goes then you need something else.
It's funny, in KS1 I had to go in again and again to ask for harder books, better maths, more differentiation. KS2 in the same school seems a totally different ballgame and DD has had so much extra stuff (good input, eg the secondary teacher for maths etc, not just random problem solving input). I'm so grateful for our lovely school. Interestingly, also, this school is v unpopular in the local area as it has way fewer high achievers than most. But my friends with clever children at more popular schools don't seem to be getting anywhere near the amount of personal attention that DD is getting. Sometimes being a massive outlier works in your favour!
