Which performance appraisal method is particularly influenced by the evaluator’s ability to write effectively?

The correct answer is the essay method, which requires evaluators to write detailed, narrative accounts of an employee's performance. This method relies heavily on the evaluator's writing abilities, as they must articulate observations, insights, and assessments in a clear and structured manner. The narrative nature of the essay method allows for personalized feedback and a comprehensive view of an employee’s contributions and areas for improvement, but it also means that the quality of the appraisal is significantly affected by the evaluator’s skill in crafting effective written communication.

Other methods, like the graphic rating scale and behaviorally anchored rating scale, use standardized formats that limit the need for extensive writing, focusing more on selecting predefined options. Meanwhile, management by objectives involves setting specific goals and evaluating performance based on the achievement of those goals, which does not require narrative expression to the extent that the essay method does. Thus, the essay method stands out for its reliance on effective writing skills.
