That's probably what you get when you are in a comparatively high socio-economic community -- if all the parents of your kids' classmates are doctors, lawyers and/or engineers there is indeed a strong possibility that more than half of them would reach the 1SD mark (which is what the 15%/85-th percentile is)? We get a lot of that around here...
I'm a lawyer-engineer. I still might go to med school.
Then I would be a doctor, lawyer, and engineer.
I've noticed that it doesn't take that much effort to simply *be* an engineer or a lawyer. And lawyers and engineers don't make that much money, on average. I suspect I would be making more as an engineer that a lawyer, though. Although I would have to work around dangerous chemicals.
Thus ends my career and economic commentary for today.
I'm pretty sure that we had a 135 cutoff for the gifted program in my school growing up. I think there were about 10-15 kids from a class of 250. Middle class area.
