Bias was studied for two cognitive tests and a personality test at three levels: the construct underlying the test (“construct bias”), method-related aspects such as response sets (“method bias”), and the items (“item bias”). The sample consisted of 13 681 participants who had applied for entry-level jobs in the South African Police Service. The cognitive instruments produced very good construct equivalence and low item bias. However, various scales of the personality questionnaire revealed construct bias in various ethnic groups. The item bias in the personality scales was low. Method bias did not have any impact on the (small) size of the cross-cultural differences in the personality scales. In addition, several personality scales revealed low internal consistencies, notably in the black groups.
