The headmistress has left and the school is currently being led by a leadership team consisting of two acting heads and two deputies. The previous head, who was at the school for many years, is also acting as a consultant. A new head is unlikely to be in place until some time in 2013. Although the gap between heads is not desirable, it was unavoidable as Mrs Rowsell left the school very suddenly (although she officially leaves in August.)
One of the deputies is leaving the school to become headmistress at Wallington.
To be honest, I doubt that we will see a huge change at the school in the intervening period. Hopefully the new head (whoever he/she is) won't change anything too drastically as it's a fantastic school as it is. I would strongly recommend it to anyone
