I mistrust maturity issues. Sometimes people just don't fit in with age mates. This may last their entire childhood or entire life and should not be used to deny them academic challenge.
Me too. Handwriting issues are also sometimes a red herring. We had a school tell us they wouldn't let our kid in the math class he needed because his handwriting was so poor. A different school told us that as long as he could communicate understanding in some way (verbally, e.g.), he certainly wouldn't be held back in math. Fast forward years later, and he still has pretty crummy handwriting, which he would have had if we held him back or not. (I'm not talking about a diagnosed disability here, just things that teachers sometimes say to hold back kids.)
