To make the linkages among claims, evidence, and tasks explicit,
the assembly models indicate the KSA(s) and claim(s) for which each
task provides evidence. Different assembly models can be used with
a single pool of tasks to produce a “family” of tests. For example,
different assembly models could be used to produce diagnostic tests
that serve as study guides and summative tests for decision-making
purposes about test takers. (Note that different evidence models
would likely be needed as well.)
