So G&T middle doesn't specialise in AS children, but it has had some and isn't fazed by another, and you have some evidence that they know what they're doing and like your DS. It sounds as though you think there's a risk that he might not get on fine there, but not a very high risk - right? On the other hand, the risk at Cozy Middle is that although his AS will be really well supported, his giftedness will not - and from what you say, it sounds as though the probability of that is high. Am I reading between the lines too much in saying that if you had both offers on the table today, you wouldn't really hesitate - he'd be going to G&T middle, despite your reasonable anxiety about its risks?
Is a day at each school really going to tell you very much? It's not long enough for him to get used to the hard new things at G&TM, nor long enough for him to get seriously bored at CM, so you wouldn't really be learning anything more about the risks that concern you. I suppose if he took G&TM totally in his stride, that would be reassuring - but if he didn't, it wouldn't tell you that he wouldn't settle just fine in a week or two, would it?
Why does it take until May to get results for tests he's already done? If you got yourself to the point where if G&TM offered him a place you'd take it, then would it be worth ringing the principal there and explaining your situation? I wouldn't be surprised if you were able to be told that your DS is in, even if they are still deciding about some other places. But of course, I don't know how their system works and may be wrong.
