I forget , what is the lowest I.Q. allowed for a Mensa group? Is there a written rule? Anyway on an average day my I.Q. hovers around 148, but let me get a couple of shots in me and BAM! - Skyys the limit.
There are different tests for Mensa, which usually accepts members who have a 98% + on their test.
On a Stanford Binet 5, you need to score 130 minimum.
DAS and Reynolds require a minimum 132.
Army GTC requires 136.
Cattel has the highest requirement, which is 148.
According to IQ founder and psychologist Dr. William Stern, these are some IQ categories:
90 to 109 - Average ( can complete high school and college with difficulty )
110 to 119 - High Average ( Most College Graduates )
120 to 129 Superior ( typical for Doctoral Degree )
130 to 145 Gifted { capable of understanding highly complex material )
145 to 159 Genius ( exceptional intellectual ability )
160 to 175 Extraordinary Genius ( exceptional talent and ability such as Albert Einstein }
It's interesting to note that there is a number of other scales were created to adjust to fluctuating general population curbs.
They almost all agree that 130 or higher is very superior with exception of Terman SB Revision
which puts the no. at 140 for very superior and Levine and Marks, which sets it at 150 { which is unrealistic }
I would stick with the Stanford Binet 5th Edition, which is very clear and precise and pretty much corroborates Dr. Stern's range, with a slightly different terminology:
90 - 109 Average
110 - 119 High Average
120 - 129 Superior
130 - 144 Gifted ( Very Advanced )
145 - 160 Very Gifted ( Highly Advanced )
This is clearly a compulsive-obsessive answer to a very simple question.
