A friend of mine recently told me that her daughter was given a 4a in literacy in her yr 2 sats. Both my children are younger so I have no true comparison, but looking at expected levels this seems beyond remarkable.
From what I can see this would involve using most forms of punctuation reliably, good paragraph structure , spelling and handwriting which seems very good for a 6 year old.
I think she may be being mischievous, to put it nicely, as she has a tendency to be a bit competitive. She has started preparation for 11plus in year3!
In short, is this likely? I am merely being curious, I am not going to call her on this , just interested and slightly amused.
