Final answer:
Reports for positions e1 to e9 within the civil service would likely require the signature of personnel at the GS-13 to GS-15 levels, as they possess the necessary skills, standards, and specialized experience.
Step-by-step explanation:
The question concerns the General Schedule (GS) pay scale and which grades correspond to the authority to sign reports for civil service positions designated e1 to e9. According to the modern GS, the pay scale within the United States civil service encompasses fifteen grades with each higher grade requiring a higher level of education and specialized experience. Reports for positions e1 to e9 would likely be signed by personnel at or above a certain GS level.
Personnel in the GS-13 to GS-15 grades are required to have specific, specialized experience and education, and thus are more likely to sign off on such reports. These grades pay the most and would have the necessary skills, standards, and experiences for signing off on reports concerning civil service activities, following the structure and requirements of the state and monitoring by supervisors and inspectors as per historical precedent.
Given the information provided where ascending levels of responsibility and education are associated with higher GS levels, it may be inferred that reports for e1 to e9 would require the signature of personnel in the higher GS grades, possibly GS-13 and above, who possess the appropriate experience and education to perform such duties.
