Statement Advice Please

[asdx2]

Dd 7(yesterday) has a statement giving her 20 hours of support per week.
Dd got her statement before she started nursery as she has autism and was significantly developmentally delayed.
Now in year two she isn't delayed at all in any area and will most likely get 3s in her SATs later this year.
At her last review LIO did say that she would need her attainment levels at this coming review which concerns me a little.
Are the LEA likely to want to withdraw her statement on the basis that her attainment is above average?
Is a statement there to enable a child to achieve their potential or to prevent them failing?
Added to her academic ability dd has no behaviour problems and actually doesn't need too much individual support at the moment.
School are working on increasing her confidence and her independence so expect that eventually she won't need any at alL.
I want to keep her statement because as concepts become more complex I suspect she will need support then to understand them and the statement will ensure priority placement in secondary.
I don't doubt school do too as an extra adult and extra funding is very welcome.
I am under no illusion that dd wouldn't get a statement if I had to ask now and don't want to lose it and have to fight to get it back later.
Anyone have experience of LEA wishing to withdraw a statement and what I should bear in mind when it comes to the review?
Many thanks

I haven't got any experience of the LEA wanting to withdraw a statement, but I do have two boys who both have statements and who have always been way ahead of their peers academically - ds1 was assessed at level 4 at the end of y2 in literacy and ds2 at level 4 in maths so just cos she gets level 3s doesn't necc mean that your dd will have her support withdrawn - in fact ds1's 'G&T status' is part of the reason for his statement

you, and the school, could make a good case that she's achieving so well because of the support in place

ime once a child is settled in a placement and things are going well, LEAs would be very unlikely to do anything to rock the boat as it would be much trickier (and more expensive) to pick up the pieces if support was withdrawn and it all went pear-shaped

That is really reassuring to read mimsum dd is also G&T so that is good to know.
It is so hard to get a statement around here and dd got hers on the basis of her being behind her peers so now that is no longer the case I worry that they will want to remove it.
Incidentally my ds has a statement too and got level 8 in ks3 math but didn't worry about his statement because of his other difficulties.
