Hi!
I left Notre Dame in 2015, other sisters left 2017 and 2020, just thought I'd give you my opinion on the school.
Teaching is okay if you're academically gifted. If you're not, they give barely any support.
Headteacher is really negative and doesn't show support to struggling pupils. Instead, she will gather them in her office in year 11 all at once when their mocks aren't great and instead of showing support and helping them, she will tell them all that they will fail and never get a good job or go to university. In all my 5 years of being there, I think I spoke to her once for a reward from the PE teacher.
Since I left in 2015, it seems to have gone rapidly downhill from the stories my sisters told me, e.g. phones out in lessons, (headteacher bans phones which I agree with 100%, but students seem to always have them out in lessons and seem to be getting away with it, including teachers allowing students to film snapchats in the PE changing rooms).
They reward the badly behaved children for being good for one lesson, I never got rewarded for my good behaviour, nor did my sisters.
Pupil wise, I was really lucky. I'm still in contact with a big group of students and bullying was something I never really experienced, however, my other 2 sisters don't speak to anyone since leaving and had problems with other girls in mostly every year (always the same group of girls and nothing was sorted out over it after many phone calls).
My advice to you would be to check the school out for yourself, you might like the school. The school itself is tiny compared to other schools, which is good in my opinion and something I liked over other schools I toured in year 6. Your daughter may like Notre Dame the best (year 7 have their own building now which is a good way to settle into secondary) and she could also have a mainly positive experience like myself. I personally had an ok experience and I do miss my secondary school days. I think if the current headteacher left and one of the assistant/ deputy heads took over, the school would be a great school, but sadly, the headteacher lacks building good relationships with her students, (whereas I would say the senior leadership team has much better relationships with students) and from my sister's experience, the headteacher really embarrassed and degraded her.
Any questions you have I'll be happy to answer them, hope this helped a bit :)
