Quick update. Had a look at Atwood, and wasn't impressed to be honest. Something about the atmosphere really grated on me. Difficult to put it into words. However, the catchment area is minute, and from what I can work out, you won't get in from Warlingham unless you've previously lived closer, and are now using the sibling rule.
We looked at St Johns in Caterham, and loved it! It's our closest church school, so we would be guaranteed a place pretty much. Trouble is, the daily schlep is just too far, through too much nasty traffic.
Finally, we took a look at Hamsey Green. Best facilities of the schools we looked at, and the atmosphere in the school felt very positive. Headmistress was very impressive too. Most of our neighbours send their kids to Hamsey green, so we've been picking people's brains. Also we've spoken to one of the parent governors, and a couple of teaching assistants there.
We didn't look at Warlingham Village - but we've heard mixed views about it. Facilities aren't good, but one of our friends has a child there, and loves it.
Everyone we've spoken to has good things to say about Hamsey, and the impression I get, is it's a school firmly on the up! It's going to be our first choice, and I'm just thankful we've got an easy school run to look forward to as a bonus!
