- Item'n Psigometriese oudit van 'n bestaande keuringsprosedure(Stellenbosch : Stellenbosch University, 2001-04) Cross, Edwin; Theron, C. C.; Stellenbosch University. Faculty of Economic and Management Sciences. Dept. of Industrial Psychology.ENGLISH ABSTRACT: A psychometric audit of an existing selection procedure: The validity and credibility of assertions made about the effectiveness and faimess of selection procedures is dependent on the methodology with which the procedure was developed and justified. Thus the process of evaluating a selection procedure in practice entails comparing the developmental history of the procedure to the ideal approach of developing and justifying a selection procedure, derived from standard guidelines, to identify and rectify any procedural and substantial shortcomings. Such a process could be described as a psychometric audit. The actuarial approach to selection is proposed as the ideal approach, whereby a mechanical decision rule is derived from historical data and justified in terms of the faimess and utility of the decisions made. A psychometric audit on the developmental history of the selection procedure for the selection of commission advisers is undertaken and various shortcomings are identified and rectified or at least recommendations are made on rectifying them. The audit finds that the selection procedure has zero validity and negative utility and discriminates unfairly.
