A lot of statistics being bandied about - but of the school not really your DD.
So many things can affect both a pupil’s individual results and the school’s results besides teaching.
Like the intake. Some schools get good results because, one way or another, they get ‘good’ pupils.
My son might have benefitted, academically, from hot housing him in a more forceful, possibly private, school. But he was happy, settled and secure where he was. He did well and is a more rounded person as a result.

Not unconnected. Some older teachers on here may remember the Fisher Family Trust.
This was a body that took KS2 SATS, KS3, CAT scores, GCSE results from across the country and processed them. The amount of data meant that you could put in a Y6 child's SAT results and predict what they’d get at GCSE - 5 years later.
Many school bought into it - some assigned it biblical truths. Woe-betide you if your class didn’t get their predicted results. (Or in some schools their predicted result +1)
A lot of water passes undef the bridge between Y6 and GCSE results 5+ years down the line. At best it was a guide.
We came up with the 5P’s
Parents
Peers
Puberty
Pot
Promiscuity …………all of which, both positively and negatively, could affect a child’s GCSE results.
