At an assessment center, multiple raters or evaluators (assessors) evaluate employees’ performance on a number of exercises.15 An assessment center is usually an off-site location such as a conference center. Usually 6 to 12 employees participate at one time. The primary use of assessment centers is to identify whether employees have the personality characteristics, administrative skills, and interpersonal skills needed for managerial jobs. Organizations also use them to determine whether employees have the skills needed for working in teams. A complete half-day or full-day assessment at an assessment center can cost as much as $20,000, so employers tend to use this method mainly for employees in the highest levels of management.
