Selection of behavior items has become the central issue of the approach. Studies such as organizational citizenship behavior, differentiation of task performance and contextual performance has put forward new issues to behavior-based performance appraisal.

Key words: critical incident technique, organizational citizenship behavior, contextual performance, task performance.
