, IOP3701 Assignment 2 Semester 2 2024
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 interpreted as falling under the definition of an unfair
labour practice”, and why? (3)
