Thanks all. Very helpful, at the very least it always helps to hear others are in the same boat and you're not out there all alone.

Chrys, schooling at this point seems to be leading towards a very costly selective school which doesn't accelerate but sets a high bar for entry. The principal said that whilst there weren't kids there at quite his level there were 'similar' kids and that they'd had kids just like him before.

I didn't ask all the questions I need to (he's yet to get in) so I'm not completely clear on what's possible there. That and it costs a bazillion dollars to go there. We're also looking into some Govt. selective schools, which do accelerate.
