A case study on a computerized test battery is presented based on more
than a decade of use in military and civil settings. The study sheds
light on the general issues associated with computerized testing. The
accent is on the contrast between computerized and traditional paper-
and-pencil testing. The computerized battery, called Taskomat, is foun
ded on concepts arising from human performance theory. The tests of th
e battery are described, as well as issues related to the hardware (co
st of purchasing, hardware reliability and industrial styling). Criter
ia used to evaluate the content of the tests were: reliability, robust
ness of effects, uniqueness or newness of abilities relative to paper-
and-pencil testing, and validity of these abilities for predicting occ
upational success. A conclusion is that a theoretical foundation helps
to increase the likelihood of assessing new abilities.
