Accompanying many warrants are potential “alternative
explanations” that must be examined and excluded to help ensure
that the logical link between the behavior and the claim described in
the warrant is correct. For example, excessively hard language in a
task may cause English language learners who possess the tested
KSAs to respond incorrectly to the task. An important part of the test
developer’s job is to reduce the likelihood that alternative
explanations for the warrants are correct.
