Final answer:
Personnel in the lower-to-mid-level paygrades (e.g., GS-7 and below) of the United States civil service typically require the signatures of a rater, senior rater, and the reporting senior on their evaluations. This is part of the 360-degree performance appraisal system.
Step-by-step explanation:
The paygrades that require the signatures of a rater, senior rater, as well as the reporting senior on their evaluations are likely referring to the United States civil service paygrades under the General Schedule (GS). The General Schedule includes fifteen grades, each with ten steps. More junior positions usually require more oversight, meaning personnel in lower grades require multiple signatures. Although it's not specifically stated in the provided information, typically, it is personnel in the lower-to-mid-level grades such as GS-7 and below that might require such evaluations and signatures.
These evaluation processes are part of performance appraisal systems such as the 360-degree performance appraisal, which includes feedback from a variety of sources. This approach aims to provide a comprehensive view of an employee's performance.
