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
