Thanks everyone and Thanks especially to Aeh! for the information on the what the test really measures and its reliability. I am sending him. He'd be bored out of his mind sitting around doing another year of the same old thing of Pre-K. I could send him to montessorri or something (so he could be others his age and still learn) and delay kindy but I really, really think it is completely unnecessary. I have just been through kindy with my older DS (younger DS will very very likely even have the same teacher) and there is no doubt at all in my mind that DS5 can not only handle it but do well and thrive. My DS5 is really tiny physically - he looks a more like a 3 year old and I wonder if that isn't playing a bit of a role as well. I think my DH is laying it on a little thick too (I should have gone). DH has been very concerned at how small DS5 is and that he will be the smallest in the class and maybe it's not a good idea to send him anyway b/c of his physical size. So I think he's got a bias. I've got news for you, he would be the smallest in the next two classes - he'd have to go when those that are now 3 to be on par size-wise.
