Actually quite telling that the HH parents find the idea of not having a tutor so unbelievable.
Here is the policy on it from my DD's school. They are serious about tutors having to be revealed to destination schools. No tutoring goes on unless school have advised for a SEN or particular weakness. Results are stellar compared to HH.
"TUTORING
All school x girls have a very full programme of academic work and we do not generally consider it is necessary or advisable for them to receive any extra tuition. If, however, we ourselves have identified a particular area of weakness, we would be in touch with you immediately to discuss things and make recommendations. For the vast majority of our girls though, we strongly believe that tutoring:
? Blurs our perception of a girl’s abilities (she might do brilliantly on a particular paper because it has
just been done with the tutor)
? Gives a girl even more work at a time when they are already at full stretch
? Gives less time for things like reading (very important for English), simply relaxing (they do need to do this), observing life and people around them, questioning, discussing, pursuing hobbies or just using some imagination
? Gives less time for spending time, talking to and learning from you
? Often involves just ‘doing more papers’ or drilling rather than anything more constructive
? Many senior schools are very good at spotting the ‘tutored girl’ and in some cases are even able to identify a particular tutor’s style. This will NOT add to your daughter’s chances!
Finally, irrespective of their possibly stellar CVs, most tutors are simply not good enough! All schools want girls who are individual, with their own backgrounds, ideas, interests, quirks and differences to contribute to their community. This will never be achieved by coaching. Many parents, who have wisely resisted the prevailing mood, panic when they hear that other girls are being tutored and it takes a strong character to hold firm. But please consider the impact on your daughter and the fact that we have 60 years of experience in preparing girls for these exams. Many senior schools will also ask you or us point blank whether or not a girl has been tutored."
By contrast I gather a lot of HH teachers have a healthy sideline in tutoring it's own pupils after school.
