I've only got experience of one of these , and it may be that all schools are like this nowadays for all I know, but if Bristol was a school, I'd say it would be Fairfield!
There's a strong focus on being a good Global citizen, reflected in a curriculum that covers Partition, Civil Rights movement, British Justice system, Protest art etc. Loads of interesting stuff that are a world away (literally) from the English-centric teachings of my youth.
It seems a friendly place, staff respond quickly to emails and were amazing when my DD struggled at the start of year 7. She's very happy now (Yr 9), super-woke, tolerant and interested in the World around her. Elmfield School for Deaf Children is on the site and lessons are shared.
I think it's academically on a par with Cotham, although obviously hard to tell at the moment. The linked 6th form isn't on site. Extra-curricular stuff has stopped since lockdown.
Overall, it feels like a school that represents the city it's in and aims to create young adults that the World needs.
