An assessment center is a technique used in the selection of candidates for a job in an organization. It is most often used to help determine which employees have the potential to be promoted into management positions. It employs a variety of techniques and multiple observers in a closed setting. Assessment centers often combine traditional assessments, such as interviews and psychological tests with simulation exercises, including in-basket (provide candidates with series of items that might be found in an inbox and ask them to indicate actions that would be taken) or leaderless group (put several candidates in a group setting with a task to complete). Trained raters would review each candidate’s performance in each exercise and provide scores. Based on an analysis of the skills and competencies for the job in question exercises for the candidates are selected in order to reveal information regarding the required qualities and attributes.
