To ignore the schools reading stuff and carry on with my own. How does one formally challenge?

[deflationexasperation]

I'm in between a rock and a hard place.

I can accept the 3 times a TA has heard 7 year old dd read in two weeks and read the level 7 books. Or, ignore that, and keep on the reading program we started in lock down, paying via company to get delivered the schools reading scheme books and keep going with those which are one /two levels higher.
Dd at the moment has undiagnosed sen, waiting for school Ed psych. Dd is on sen register but, unlike the other two on sen register is not sat at the front and has been sat at the back? I asked at the start, why and got no response.

I'm at a critical juncture with dd, she's very sensitive, possibly dyslexic but very bright. I'm deeply unhappy with the school, moving her has been looked into it and I'm not sure what to do. It's only with outside help, and then buying in tutors and myself, working with her in lock down that she's actually learning.
I know from older dd that reading levels are a cause of angst but dd will only read one thing a day.

Sirzy thanks for the link @steppemum

The spelling was a spelling board with a rainbow print on it and foam magnetic letters.
So they pull the letters down from the alphabet.
Once she got used to that, eg would, also used the oh, u, lucky duck stuff and followed practise up with a whiteboard and pen.
The change was remarkable..

Some dc are visual learners! They just need to visually see what the words mean in context!

Dd gets who /how, was /saw /, 3 and 5, d and b mixed up, for, off and of.

I'm going to try and order colour things for her to see if that helps.

Midnight, she hasn't been pushed hard at all.

She's just had to read a little every day over lock down. She's spent nealry every single hour of lock down doing exactly what she wanted 😂😂, mine craft, roblox, films, garden etc.
