A candidate's suitability can be better assessed through the use of individual/group exercise simulations which require elicit responses to real (or very close to) work situations.
An assessment centre is a process whereby participants are engaged in one or several simulation exercises involving particular tasks or skills needed for the role. All assessment centres are supervised by organisational psychologists.
The core-competencies required for a role are determined by the company and are used as a basis for developing the tailored simulation exercises. These exercises are designed to accurately measure competencies through the participants' behaviours, motivations, and specialised skills and knowledge.
At the conclusion of each assessment centre, detailed individual reports are written by the psychologists to summarise each candidate's strengths and weaknesses, areas of risk when hiring the individual and potential development needs.
Simulation exercises can be completed either in a group or individually. Working in a group includes discussion exercises while individual exercises will typically include a one-on-one exercise such as an interview, fact finding, verbal presentation or analysis exercises.
