As I said: Most reputable tests. Not all of them.

The Stanford-Binet goes from 40-160 for example.

One of the "extreme IQ" organisations, the Mega Society claims to only accept those who are in the 99.9999th percentile, thus, 1 person in 1 million, however, they accept untimed, unsupervised IQ tests (Which most standard accepted ones are not) and they also have their own test which they forumulated specifically to give to people seeking entry.

Whether someone who scores a sufficient grade on their test would also show the same results on other tests is open to debate, and depending on the standard deviations of the test in question, it is possible to score a perfectly correct result on their test and still not read as high enough to qualify for these super elite clubs and groups.

I mean..."We only take people that scored in the 99.9999th percentile on a test that claims to be able to measure to the 99.9999th percentile" doesn't, to me anyway, prove that their IQ is sufficiently high, or that they'd score that well on any other test.
