Move from state to pre prep - yr 2

[Offerdecisionneeded]

Just looking for some reassurance (hopefully)

Moved my 6.5 year old daughter from state to pre prep to start Year 2 this week.
From the little bits she’s told me, she says ‘everyone is better than her at reading’ and she was quite upset tonight about it. I think another kid was talking about book bands and made a comment about everyone being on higher colours but my dd said it was said ‘in a kind way’.

My worry is that she IS behind and will feel this more and more and it will knock her confidence. She was higher end in her state primary and meeting/above expectations for everything.

For those who’ve experienced state to private, any words of wisdom?
She’s otherwise quite happy, no fuss going into school and made lots of friends already.
(I know we’re only a few days in)
Oh and she left her old school on level 7 ort and brought home level 6 last few nights…

Like @Thingaling said, London/ West London is being taken over by private equity holdings like Dukes, Alpha schools and the other one that owns Fulham Prep (can't remember its name). All private equity owned and running for CASH and profit. Money is going to marketing, freshly painted walls bu you have to do you DD on the actual day to say running of the school, how happy the teachers are and the actual quality of teaching. They have some debt to cover for and some investors to account to - definitely a business first. Sad too see really in this part of town (West London)
