teach year 5/6. teachers are careful about how they phrase things - but I suspect it all came from thee same teacher due to his age?
I would ask to see her before the holidays with a list of phrases which concern you and ask her to elaborate.
Maybe in september these things can be looked into further?
Have you had any concerns before now? has the
teacher approached you before?
If ds1 had these phrases I would ask to speak to his teacher first for elaboration and possibly to the senco
Can you give us some of the positive things she has said too?
