[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]Kids in the 99.99% percentile have at least 40 iq points on the kids in the 90% percentile. That’s a really big difference in smartness and what they are capable of achieving in college and beyond. [/quote]

I do not know why posters are mocking this. It is very close to correct:
90th %ile is about 120 IQ, is too low for gifted and talented programs and [b]is a little above the average IQ (85th %ile) of our local UMC public school [/b]and a little below the average IQ of the local private. They give the parents all the CTP testing data.

99.9 is 147-150, about or 1 in 1200 people. 
99.99 is 157++ and is hard to test; the ceiling of the normal tests is around 99.9. True 99.99 are rare 1 in 11, 000
 
So yes 90%ile IQ about 120 and 99.99 about 160 is indeed about 40 points. 
It is a vast difference as far as what they are capable of. I am in the gifted and talented field and spouse is a professor who has taught at many schools—the IQ/talent level of the average student matters a LOT and 40 points is a huge deal, even 20 points (120 vs 140) is a large range. [/quote]

Which public school is this? Is it local? I am surprised average is that high. We are in MCPS (one of the W clusters).[/quote]

DP: I just looked up my kid's high school and my own high school (current SAT not 1994) and they are in different counties in central virginia which are known for having good public high schools, both send a chunk of kids off to Maggie Walker Governor's school after 8th grade and yet  have SAT average of 1260 and 1280, both above the 85th percentile. I know it is not IQ per se, but this is the average SAT after a couple dozen of the top students leave the county system for Maggie. My guess is there are many such schools around the country.
