==Remember 50% of the population is below average in
intelligence [and almost all other factors]==. I am still
looking for a study showing the median/average and 1st
decile [cutoff] IQ distribution for these "high-tech" and
other positions, so I can compare to the known adult
population IQ distribution. There are of course categories
within the aggregate IQ score which may be more significant
than aggregate IQ such as spatial
discrimination/visualization.

This is old problem for the military. I went through an electronic
school with a very high failure rate. AFAIK they used it to sort
recruits by skill level and sent the dropouts to appropriate other
classes.

When I enlisted in the Air Force there was almost a week of tests
during Basic. It was obvious that the "dull thuds" were assigned to
either Cooks & Bakers or Supply as their first assignment.

However, years later I was assigned temporally to a detachment that
wrote the skill tests for my specialty. The wording of both the test
questions and answers were aimed at an 8th grade level of reading
comprehension. Which was, we were told, the standard for all USAF
technical manuals.
