The correct answer is: C. Impartiality in evaluation
A points-based rating system is a performance evaluation system in which employees are rated on a scale of points, with each point corresponding to a different level of performance. The most essential requirement for an effective points-based rating system is impartiality in evaluation. This means that the evaluator must be objective and fair in their assessment of the employee’s performance. The evaluator must not allow personal biases or prejudices to influence their rating.
Close coordination between the management and the HR department is important for the success of any performance evaluation system, but it is not the most essential requirement for an effective points-based rating system. Comprehensive, dependable and consistent information is also important, but it is not the most essential requirement for an effective points-based rating system.
In conclusion, the most essential requirement for an effective points-based rating system is impartiality in evaluation.
