Hi - I used to be at the Dragon (in the late 1980s) and all three of my kids (14, 12 and 9) have been/are at the school. I'm conscious that other parents / pupils will experience a school differently, but our experience has been overwhelmingly positive.
All our children are very different in terms of character, interests and academic abilities, and the Dragon has worked/is working really well for all three of them. I think the school is in better shape than it was in the 1980s - back then some teachers were brilliant and some were treading water whereas now the standard is high pretty much across the board. I also think the school has got better over the time our kids have been there, which I appreciate differs from some other people posting here.
Going back 10+ years as prospective parents, we had heard that the Dragon had a bullying problem and it definitely spooked us. But our kids experience did not tally remotely with what we had heard beforehand. While we have become aware of isolated incidents of bullying, we've also seen how the school has tackled it. Again, I'm conscious it is a large school and this may not be everyone's experience so I'm not trying to minimise the other comments. I'm just trying to point that this is not a universal experience.
Our experience of the pastoral side has also been excellent - both for supporting one of our kids when they weren't happy, and for supporting us and the kids during on-going period of parental poor health. As a large school, it means they have a lot of specialist support and a broad range of pupil/parent experiences. We've leant on this heavily at specific points.
My final note is on the Headmistress, who I think is really great and this certainly seems to be the overwhelming feedback from parents we know (which is quite a large group given we've had kids in three different years).
Every pupil and parent will experience a school differently, but it's worked brilliantly for our three. I'd really encourage any prospective parent to speak to as many current parents as possible to work out whether it's right for your kid(s). In our experience, nearly all the parents we know would make the same choice again and think it's an excellent school.
Ps - am not affiliated with the school in any way other than as a parent, and a former pupil who loved my time there
