Very late to this, and you probably have made your decision, so apologies but maybe this can reassure/help others.
Current Channing senior school parent. Clearly just my opinion/experiences - am sure plenty of others are also available.
The school is very strong on pastoral care, with well established channels that are constantly advertised to the pupils to address any issues that come up. I have seen them be proactive in dealing with problems, and get external support in quickly to nip issues in the bud where needed. Yes eating disorders crop up, and teachers monitor, but frankly this is no different to any school, even in co-Ed state and yep, boys schools! From my understanding they have fewer issues than most schools as they invest time in prevention and catch many issues before they escalate. They have an excellent reputation with healthcare professionals who deal with the issues that do crop up. (Have a couple of Ed. Psych mates who are v. complimentary but also have heard a number of second hand sources all reporting similar things)
Don’t understand the parents are cliquey comments as we rarely see each other outside of school events. ;-) (a contrast to the Junior school which was very social.)
Kids come from a variety of backgrounds, with a catchment that has increased over the past few years as it has expanded, and yes, a fair number will never have to reckon with a wolf at the door. Also a lot of parents there who sacrifice to pay the school fees and the overall profile seems broadly similar to any other independent school in North London. A wide range of international backgrounds but would agree that senior school is not that diverse ethnically. Junior school is now a different story, and I suspect that this comment will fall away as these cohorts work their way up the year groups.
School uses a higher portion of fee-income than most to support the bursaries they offer, but lack the endowments that fund many schools’ Schemes.
IMHO It is academic, with plenty of stretch at the top end, and support for those who need it, has great drama and music, truly supports each girl in theIr intellectual and emotional development, builds articulate, interested and resilient young adults and needs to do better with sport.(shame).
