Introduction to Assessment Centres

A full day workshop during the 2023 Virtual ACSG Conference on Wednesday, 15 March 2023 from 08:00 - 17:00 SAST

The purpose of this workshop is to provide delegates with basic knowledge on the use of assessment centre technology. The aim is to provide delegates with an understanding of assessment centre methods so that they can make informed decisions on how and where assessment centres can be used in their organisations. Delegates will not become assessment centre practitioners after attending this half-day workshop but will at least have a good source of reference on which informed decisions can be based.

The topics that will be discussed are:

  • What is an assessment, diagnostic and development centre?

  • Uses of assessment centres;

  • Why are competency models important in assessment centres?

  • Types of assessment centre exercises;

  • Compiling an assessment matrix and the selection of appropriate exercises;

  • The role of the observer;

  • The process of data integration and report writing;

  • Feedback principles;

  • Assessment centre ethics; and

  • Steps in designing an assessment centre.
