My experience: My then-5yo had just short of qualifying WPPSI scores (148 FS, 143 PIQ, 144 VIQ). He did have several qualifying achievement scores, but they asked for more info. I put together a pretty strong portfolio and he was admitted with that.

So, it doesn't hurt to apply. I think they'll want to see qualifying achievement *and* a good portfolio, though. Any chance of getting achievement testing done? It'll be helpful not just for Davidson, but for you as well.
