We have a very happy year 7 at St clement Danes ..
Our DC came from a single sex private school and we were worried it would be a huge change, but they love it!
The facilities are excellent, the teachers seem to really engage the students and make the lessons interesting. We have already met many of the parents in DCs form and have everyone's contact details (group chat) etc so you don't feel out of the loop! Already social dates in the diary which is unusual for senior school I believe??
I feel that going to a mixed sex school was right for our dc at this age too. We also think Dr Valentine is an excellent head teacher, so feel very lucky we were able to gain a place at this school. The only other school we looked at was parmiters but SCD was the right school.
Good luck with your difficult decision. If you need any further info feel free to DM me
