On one subject. My son is only 2 years ahead in reading, but 5/6 years ahead in Math, without doubt he is gifted, even he is normal in reading.
Smeone used to think 3 years ahead in young age should consider HG.
In my point of view, Normal kids can not be taught reach that high level,children can be pushed ahead 1 or 2 years but they need certain ability to learn fast.
To be honest, it is not that "hard" to be gifted, depends on which school you kids are. Most of my friends kids could be gifted, because most of my friends has high education degree, that make my son "less" gifted or normal(in reading)
