The content validation study was conducted
at an independent community bank in Florida.
The Computer Programmer I must accomplish
fourteen tasks to successfully perform his/her
job responsibilities. Within the scope of testing,
a total of 55 traits were judged to be essential
to accomplishing these tasks. Of these 55 traits,
35 are assessed by one or more questions in
the International Programming Aptitude Test.
Thus, a significant portion (63.6%) of the intended
domain is assessed by the IPAT. As well, if the
relative importance of the essential traits tested,
to the ''weighted'' importance of the task, is
considered - the overlap percentage improves to
64.8% for the Computer Programmer I.
Given the demonstrated relationship between the
abilities and traits required to perform the fourteen
key tasks of the Computer Programmer I job, and
those measured by the IPAT, the test represents
a content valid evaluation device for that job.

The concurrent validation study was
conducted at a large and prominent
university (Concordia University) in
Montreal, Canada. A sample of 81
candidates who were enrolled in four
different programming languages
courses as a part of an intensive
computer certificate were evaluated.
The results showed a statistically
significant relationship exists between
the IPAT scores and overall programming
success (i.e. course grades).
The correlation coefficient (r = 0.345)
is significant to the 0.01 level and
indicates that the IPAT is highly predictive
of success with respect to programmer
language training.
