What additional requirement must agencies fulfill regarding 10-point preference eligible applicants?

The correct answer highlights the obligation of agencies to inform 10-point preference eligible applicants about application handling procedures. This is essential because 10-point preference eligibles, who are often veterans or individuals with disabilities, have specific rights and benefits in the hiring process. By ensuring these applicants are aware of how their applications will be handled, agencies promote transparency and fairness, allowing applicants to understand their status and the steps in the hiring process. Keeping these individuals informed aligns with overall equitable treatment and supports compliance with veterans' preference laws, enhancing inclusivity in federal hiring practices.

Other options do not directly address requirements related to preference eligible applicants. For instance, classifying all applications pertains more to initial administrative procedures rather than specifically to the needs of 10-point preference candidates. Conducting interviews before application review is not a standard requirement and could create barriers instead of promoting fair opportunities. Setting quotas for hiring would violate merit system principles and could lead to unfair practices in federal employment, as hiring should be based primarily on qualifications rather than numerical targets.
