An assessment center is a structured and standardized personnel assessment method used to evaluate the behavioral competencies, performance potential, and development needs of employees or job applicants. This approach typically involves 6 to 12 participants who are observed and evaluated by a panel of trained assessors over one or more days through a series of practical exercises and simulations.
Purpose and Structure
Assessment centers are used in both recruitment and human resource development, helping organizations identify both strengths and gaps in participants’ behavior and decision-making.
To ensure validity and relevance, assessment centers are tailored to the specific job requirements or organizational roles participants currently hold or aspire to. The observers (assessors) are thoroughly trained and follow predefined evaluation criteria aligned with the role profile.

The assessment center process typically includes the following stages:
-
Defining objectives and identifying the target group
-
Selecting and training observers
-
Developing a requirements profile (competency framework)
-
Designing and organizing assessment exercises
-
Conducting participant assessments
