For people who are interested in if there is a correlation.
When I had first written the test (@ 21). I did not qualify for Pilot, I didn't even make Officer.
Ironic because later I graduated with a degree in Engineering & another in Physics - with very high GPAs's.
As a result of my success in University, I was forwarded for psychometric testing (IQ) on the Stanford-Binet and Weschler Adult Scale, which were administered by professional psychologists. I scored
close to the ceiling (145). I made one mistake on a verbal question.
Several years later, often still wondering what happened on the CFAT. I decided to write it again - after making a few changes in my life & attitude.
I qualified for Officer, with all trades about two years ago - including eligibility for pilot.
So what happened the first time? How did I fail to make Officer - the first time?
#1. Applicants with Mathematical/Science degrees, may have become overly reliant on calculators for the purpose of solving complex questions. As a consequence their basic arithmetic is hindered. Don't let your background make you over-confident. Believe it or not, there ARE things that you did better when you were 14 than you do now. We don't give basic arithmetic (multiplication, decimals, long-division) much thought these days, because we're too focused on solving triple integrals and partial differential equations. Whilst, you may still know how to do basic arithmetic, chances are your SPEED is horrible.
This is really important, because I was in shock, my recruiting officer was in shock and the Officer panel that interviewed me (in which I successful) were also shocked. CF were so confident in my abilities, that I had my officer interview before the CFAT or Physical. They thought I would ace it without a hitch. That little pamphlet/flyer with 5 questions and my arrogance ultimately betrayed me.
Anyways, getting to the point - in terms of correlation with IQ.
When I had written the CFAT recently, I am positive that I made only one mistake - in the verbal section. I had plenty of time to try to figure it out - but to no avail. The rest of the test, I blazed through it with plenty of extra time in each section.
This *may* imply that the CFAT when statistically normed against legitimate psychometric IQ scales (Weschler, Stanford-Binet) - may have a ceiling of around 145. Of course, this can be argued as scores on a professional psychometric test and the CFAT may not be comparable due to different population samples - I know this. This is merely a hypothesis.
Therefore, to qualify for Officer, this may suggest a percentile score of 75% (top 25% candidates) - which may yield a minimum Officer IQ between 115-120, if you overlap this on Normal distribution (bell curve).
Before you go run off to write online IQ-tests. Remember that online-IQ tests are hardly representative of real IQ scores. IQ scores are standardized, normed on proper samples and tested in controlled environments. You could try an online-IQ test for the sake of seeing whether - you are way off or not - in either direction. But remember, it will hardly be a precise or reliable measure.
However, if you have been officially tested (for whatever reason, usually because of an Individual Education Plan (IEP) these days) - this may give you a rough benchmark.
