Hi firsttimer,
Do you have any specific queries? We have been there since the little one was 2. For the early years, I really don't think there is a better place. Great pastoral care. They are very well taken care of, learn so much (without realising they are learning), get good warm food for lunch. The teachers are extremely approachable and at least I feel that we are working as a team.
On the 4+/5+ debate, yes, they do ask you to let them know if you are sitting assessments. And yes, you are not guaranteed a spot for reception if you are sitting assessments (like it would be at any nursery I suppose). But, again, as I said, it is not antagonistic rather a team approach. Friends who left at 4+ had a chat with the headmistress and were quite pleased with her feedback on the child, which school they would be suited to etc. The children were prepped for the assessments. There are lots of kids who have gone on to their number one choice schools at 4+/5+.
However, from Reception onwards, the school is a bit of a mixed bag. That is a whole other conversation.
So, finally, for a 3 year old - go for it! Its a great place!
