It doesn't matter if a DC is WORKING on level 4 in Y2, the SATS will only report a level 3. Because the papers don't actually have questions on L4 work. I have a DS, my DS1, who was consistantly working on level 4 in Maths in Y2, and he was given Level 3 in his SATS hence me questioning it.
They can't give a mark that isn't available on the test IYSWIM.
It's a bit like GCSE's - if you sit a Foundation paper, the highest grade you can achieve is a 'C'. If you get 100% in the test - you will STILL only get a 'C' grade.
Y2 SATS are like this - even if your DC gets 100%, they can only achieve a L3.
DS1 is now just finishing Y5, and is working at L6 in Maths.
I wouldn't have wanted him moved up a year, God no! He is very ahead academically. But if he had been moved up a year, he would be going into Secondary school in September...he is 10yo! Just because he is advanced academically, it doesn't mean he is advanced socially. IMO, good differentiation IN school, and extra work at home too, is a much better option for 99% of advanced DC than being moved up a year.
The school teach him, two other boys, and a girl from his year in a group of 4, working on L6 maths, in the library. They differentiate the work perfectly well for the more able DC's.
Just wish the school were as good at doing that with the DC's that were behind, but that's a story for another thread...
