What does a valid performance appraisal accurately measure?

• A. Only personality traits of an employee
• B. Each employee's educational background
• C. Job-related behaviors and goals
• D. Supervisor's expectations of the employee

Answer: (C)

A valid performance appraisal is designed to measure job-related behaviors and goals because it provides a structured way to assess how well an employee performs specific tasks required by their role. This focus ensures that the evaluation reflects the actual work performance, productivity, and contributions of the employee to their team and organization.

Measuring job-related behaviors enables supervisors to give constructive feedback, identify areas for improvement, and recognize outstanding performance based on established criteria that align with the organization's objectives. By concentrating on relevant behaviors and achievements, the appraisal can help in setting future performance goals and in professional development planning.

In contrast, assessing only personality traits may not give an accurate picture of an employee's work performance as these traits do not always correlate with job effectiveness. Evaluating an employee’s educational background is not directly related to their current job performance, and measuring a supervisor's expectations without linking them to actual behaviors can lead to biased or unfounded evaluations. This makes the emphasis on job-related behaviors and goals a cornerstone of an effective performance appraisal system.
