Cross-cultural fairness requires verifying that the test is appropriate for use with a particular population and includes investigation of validity, reliability, and appropriate norm groups to which the population is to be compared.

The instrument must be validly adapted, the test items must have conceptual and linguistic equivalence, and the test items must be bias free.
