There are no hard and fast boundaries between moderately and highly gifted. It's not like two people with a single point difference in a test score are profoundly different from each other. I myself came to this forum with the understanding that my DD is moderately gifted, based on her assessment. And then in conversation with others here, a consensus emerged that, no, it would appear that my DD is more accurately described as highly gifted, and the problem was with my definitions of those terms.

Meh. They're just labels. They don't change who she is. I still have to parent the child I have in front of me, and if viewing her through the lens of OEs and being similar to highly gifted children is a useful tool and helps me accomplish that... great!
