Data-driven item selection for the Shirts and Shoes Test.

CONCLUSIONS: Item Response Theory can be used productively to identify items that fail to add to the reliability and validity of a test during the earliest stages of test development. The number of items culled for this test demonstrates that the content of the items alone does not assure that the items perform in ways that promote accurate skill measurement.
