The purpose of empirical criterion keying is to identify items that discriminate between the two groups (i.e., those who exhibit the trait and those who do not). By retaining these items, the test can accurately measure the presence or absence of the trait in future test-takers. This method does not aim to increase the size of the sample, use a matched standardization group, or include a specific subgroup of people in the normative sample.
