We keep getting this "reason"... Every child needs the opportunity to work on his/Her weaknesses. Your child's biggest weakness is an inability to handle boredom. So no grade skips until he masters being bored.
That's amazing. Obviously they must not realize how inane that sounds. I can see the need to master the fine art of patience, but to be able to handle boredom? This reminds me of what my dad used to say when I was little and complained of being bored: "An active mind is never bored." Which reminds me of the whole caged up cheetah analogy. Just see what our kids can do when you unleash them from the confines of this unnecessary daily grind... Anyway, you should tell them "Don't worry, I'm sure he'll have plenty of practice being bored in the next grade up, too." (Ok, maybe you shouldn't say that, but, geesh...)
