Looking for a school for my 16-year old daughter.

Good Day Don

There are numerous quality schools in London for your daughter. However, I'm not certain whether you're query is regarding a 'state' school, or 'Private' schools. I won't attempt to confuse you with the often confusing concept that here Public means private, etc. I am an Anglican priest based on the south coast. However, I was based in the London area for years. Are you interested in a fee based school? If it is Private school, you'll have some flexibility.

Have you ascertained in which part of London you'll be working and residing yet? I'd be pleased to offer some schools for consideration. It would also help if you could identify where you're moving from. Generally, the British education system can be more comprehensive than US Public schools, especially when coming from certain states.  I don't wish to waste your time recommending anything that isn't commensurate with your daughter's requirements, so any additional information can provide would be greatly appreciated. Your daughter is at that important transitional period where she could be moving to a 'college' setting, dependent upon her curricular achievements.
In any event, welcome to the United Kingdom. This will be a profoundly positive experience for both you and your daughter. I cannot imagine a better opportunity for her, as she experiences how beautifully different our culture is on this side of the Atlantic.
