Hi,
I cannot recommend strongly enough that you do NOT send your daughter to The Old Vicarage. I am not actually a parent- I went there myself, twelve years ago. OVS cares more about its flawless school uniform (complete with "summer boaters swinging through the park") and "castle on a hill" image than the happiness, or even the success, of its girls.
As has already been mentioned, the school suppresses individuality, encouraging all of its students to follow the exact same paths. One of my teachers once laughed at the idea that any one of us might not go to university. That, of course, does not take into account for those girls for whom university might not be the right course to take; who might have other strengths or passions in other areas.
The school is very academic, and usually gets good secondary school placements for its students. Part of this is because of the absurdly high workload, the public humiliation which terrifies the girls into working all hours rather than falling behind and the prioritisation of those subjects needed for 11+ at the expense of anything else. This is also partly because, although OVS is not selective, the girls who go there tend to be the daughters of wealthy parents who can afford the necessary tutoring.
For me, although negative, it was not a hugely destructive environment. However, I am still in touch with many of my ex-classmates, and, unfortunately, for some of them, it was. In my year alone the school turned a blind eye to a lot of emotional and physical bullying. I would even argue that the treatment of some of the teachers towards the students could err on bullying. As far as I know, there is no form of pastoral care.
I know the headteacher, Mrs Linthwaite, personally- she taught me Geography from a young age and was the headteacher for my final years. My younger cousin stayed at the school two years after me, so I kept up with her policies.
One of her new policies apparently involves confiscating snacks off girls (and showcasing this in front of others) if they are deemed to not be healthy enough. The example I was given was chocolate digestive biscuits. Publicly shaming young girls about what they are eating surely only serves to encourage fear of food and body hate from a young age. Considering society's increased awareness about food-related mental-health issues, it honestly shocked me that anyone could think this a good idea.
It is worth mentioning that the school is under a huge amount of pressure from its catchment parents and much of its problems stem from trying to live up to the absurd demands and priorities of Richmond Hill parents. Of course, if you fit into that category, and this is what you are looking for, then you may be perfectly suited for OVS. Your daughter probably won't be, but she's too young to have a say.
Thanks for giving this your time.
