I agree with some other posters, it's a sad world in many ways when people feel they can't celebrate their DC's achievements, whatever that level may be.
But I think the problem is that on these kind of threads, a large majority of posters seem to be parents of DC attaining level 6's which (a) skews the reality for most of us and (b) gives the thread an appearance of being a boastful bragging smug fest when it actually really isn't. At the end of the day comparatively few DC will attain L6 at the end of KS2, so clearly there's a disparity between 'reality' and what MN threads might suggest as 'reality'.
Here's my contribution, for what it's worth: my Y6 DS wasn't entered for any L6 papers, nor would I remotely have expected that he might be. He is not in that 'league' academically. We are over the moon with his achievements though: L5 in everything except maths, where he was teacher assessed as a 5 but scored a 4 in the test.
I know there have been comments earlier in the thread about how SATs are meaningless, pointless, only for the school's benefit and ignored from here on in etc etc. But I'd disagree with that. DS hasn't always found school easy (late summer birthday, some SEN, really struggled during the infants school years in particular). He is so bloody chuffed with his SATs results. And he so totally deserves them. He's a lovely bright capable boy who has never really believed it - partly because he's in a school with lots of L6 type high achievers, partly because of his SEN - but when he came out of school earlier this week, excitedly brandishing a near-clean sheet of 5s, I think the penny finally dropped. DS is walking tall this week and it's lovely to see.
So
to all our brilliant DC - whether 'brilliant' means a L6 or a L3 or a L1 or a W - and
to all their parents too.
