We have son at the Mead that has been there since Kindergarden.
We love the school. The teachers are amazing, it very much has a small village primary style school feel, but with 15 kids in a class.
In every school, there will be people complain. Yes, the Mead doesn't have significant sports grounds but instead uses the local grounds - and when it plays against local preps, they often come out on top. It doesn't have its own Theatre - however, the school does an annual summer show, held at the local theatre, and the school has a reputation for producing theatrical performances.
All we would say is it depends on what you want; there is no point going to The Mead if you value large sports grounds, or you intend to stay in the independent system.
If, however, you are clear that your objective is to get your kids an rounded grounding to get into the excellent local grammars, then The Mead is a super option.
Most importantly, all the Kids we come across seem to love it there!
