Final answer:
The performance appraisal method using a scale to rate employees is known as a Graphic Rating Scale.
It is a common method for annual employee evaluations and differs from ranking methods or 360-degree feedback appraisals.
Step-by-step explanation:
The performance appraisal method described in the question, where management evaluates employee performance annually using a six-page form and marking one of five performance categories ranging from unsatisfactory to above and beyond expectations, is known as a Graphic Rating Scale.
This method relies on a scale to rate employees on various aspects of job performance. It is distinct from other methods such as ranking, where employees are directly compared against each other, or 360-degree feedback appraisal, which involves multiple sources providing feedback on the employee.
Graphic rating scales can be part of a comprehensive performance appraisal system to motivate and improve employee performance, aligning with both the organization's goals and the employee's professional development.
