Yes. Because her level, sadly, will determine her expected grade at GCSE.
I'm a secondary English teacher.
If your child got a 4 in year 6, I'm expected to convert that into a C at GCSE. Level 5? I'm in the shit if they don't get a B. Level 6? Better be an A/A* then.
So, as the mother of a lazy but bright Y6 ds, I am snapping at his heels to get that level 6. Because if he gets the 5b/a he can get with no effort, he'll be allowed to gently coast through secondary achieving Bs, also with very little effort.
It's a crap system (& it's changing, but all a bit too back of the envelope for my liking) but yeah, I want my lad chivvied a bit to achieve his potential at secondary - not cheerfully kicking back in set 2 with less able kids who are having to work bloody hard for the same 'good but not great' results!
So in OP's shoes, I would be seriously bothered. Either the school have been over-levelling to a startling extent in previous years, or something is very, very wrong with OP's dd's level of engagement. Something is off here.
