Hi techXX - Welcome! Sorry we missed your post. I don't have time to respond much, but I wanted to bump your post so others would see it. I am sorry you have to deal with such an unreasonable preschool teacher. I remember when my kiddo's kindergarten told us that she "just didn't see it" when we told her of our kiddo's advanced verbal ability. It turned out that she was right, though - she didn't see it because our kiddo was super shy and didn't want to stand out or speak up in class.

I will try to post later. I do think you should have some strategy if this teacher will keep your kiddo out of GT programming next year.
