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.
