thanks for the additional details about the Iowa Scale. The Hoagies review especially helped me to understand what data goes into it.
The best thing about this potential skip, I think, is that it is pretty flexible. I believe I could even keep her labeled a 3rd grader and put her into the 4th and 5th grade class which would make it easy if we wanted to keep her there for 2 more years. We could start off that way and then make her an official 4th grader at some point during the year if it was working out or leave her at 3rd if we wanted to keep her there longer. The school is adding middle school next year though I do have qualms about keeping her in such a small school environment. The middle school group is expected to be about 20 children in 6-8 grade. Our other option is the public middle school. They are supposed to be pretty good and one of them has a fairly new fully inclusive gifted program. Hoping they will start one in the other school though which is a couple blocks from our house while the other one is 10 min drive. I've also considered transitioning her back to the public school before the transition to middle school. There is a 4/5 class at the public school that is supposed to be pretty advanced. I am sure it would still be a step backward to go there but if we go to public middle school then it might be worth it. I'm not sure about the homeschool option. I am not sure it would work that well for us.
