I don't see DH agreeing to a skip no matter what the Iowa scale says. He believes in science and understands the research, but he can't get over the idea of how small my (1st percentile for height) kid would be in a class 2 years older.

I think we have to see what the school can do for us, and perhaps revisit the grade skipping conversation at a later time.

Personally, I'd gladly skip him, and he wants to be skipped. So we've got that going for us.
