Had my daughter remained at the state school she would still have been expected to get 10 grade A's at GCSE, the same as she is predicted to get at her private school. It wouldn't matter where she went to school, that's the sort of child she is, she will achieve whatever, as someone further down said.
But, if you ask her where she'd rather be, she can't exactly tell you why, but she knows that she's in the right place.
Yes, I believe private education can give you an edge in confidence etc. I am still a governor of a state school so I see the difference. The girls at the private school have far more poise and self assurance, at a risk of being told I'm a snob, it gives them a bit of' breeding' they are constantly told, you will succeed, you are young women, etc.They are sent out into the world far better equipped to cope with all ssorts of situations, well, that's my opinion and experience. It is not a pressure to succeed, but they are encouraged to achieve as much as possible, but with a good all rounder bit thrown in.
I just wish I had made the decision to send her at 11, but despite that, the teachers say it is as though she has been there all her life, and it wouldn't make any difference to her academic ability.
I know that my son has been damaged by his experience at state secondary, it shattered his self esteem and confidence, it has taken nearly two years of hard work on behalf of the committed caring staff at his new school to start to produce some work of a reasonable standard, hopefully not to late!
