Don't worry Kate - I don't think my concerns take precedence over anybody's! (And I go up & down all the time in my feelings about ds, so the Gloom below was just a bit of a bad moment, oh and possibly a self-dramatising melodramatic one . School may not be planning to say anything Heavy at all.)
Now you. It sounds like you have two issues - how to wake your dd up a bit generally; and whether, if the standards she has to live up to (at school) are lowered, she'll do herself justice in the long run.
On the second issue, have you seen tortoiseshell's current thread about her ds? (OP is about coaching/doing extra work etc., but the gist is the same - how can you be sure a child is learning to its real potential.) As for tortoiseshell, I'd think your first port of call is dd's teacher? - find out exactly why she's been moved?
On the first issue, a long long time ago there was a thread (started by me, I admit) which asked those of us who were dreamy at school how & when we got out of that. The universal, fascinating, message was - we grew out of it: usually around adolescence. That may not be very helpful to you now, but it might give you strength for the future.
Also on that first issue, and depending on how old your daughter is, something that I have found wakes ds up is real responsibility, where he can't passively rely on somebody else compensating while he zones out. So - for instance - he's wonderful if I send him on an errand to the corner shop.
And another example: this morning he & I agreed he was going to be in charge of getting to school (we go on the Tube). We got to our stop - but he gazed out of the window - I bit my tongue - the doors shut and on we went. We had to go on to the next stop, change trains at complicated station (all done by him) & scramble back to be at school by skin of teeth.
I am quite looking forward to tomorrow's trip to school as, now he's had to live through the frantic consequences of zoning out, I do NOT think that will happen again.
