The concept of unfair labour practice has been introduced into South Africa through the
Labour Relations Act and it is argued that certain psychometric testing practices can be
interpreted as falling under the definition of an unfair labour practice. Empirical results
are presented indicating that different ethnic groups obtain significantly different mean
ability test scores. A case study is cited to show that this would result in an
underprediction of performance on a criterion for the lower scoring of two groups if test
scores are regarded as comparable. It is argued that any interpretation of psychometric
data in South Africa that does not take into account of possible differences between
ethnic groups is likely to ignore a significant moderator variable, given the history of
ethnically based discriminatory practices in this country. Arguments based on meta-
analytical research in the USA, to the effect that psychometric ability tests do not
discriminate unfairly against disadvantaged groups if the same tests and norms are
used, should not be assumed to hold in South Africa. Various conceptions of what
constitutes fairness in selection are considered, and it is concluded that there is a need
for employers to make explicit in their selection policies the trade-off between economic
and social costs of employment practices. Finally, some implications for users of
psychometric tests in industry are considered, to forewarn of likely developments in this
field.
1. Do you agree with the statement that “certain psychometric testing practices can be
