Which statement is true regarding the merging of categories of candidates?

The correct statement regarding the merging of categories of candidates is that it is optional based on circumstances. This means that the decision to merge candidate categories should be made with consideration of specific factors such as the number of qualified candidates available, the nature of the job being filled, and the needs of the hiring agency.

Merging categories can often facilitate a more streamlined selection process, particularly when there is a limited pool of candidates, but it is not always necessary or advisable in every situation. For example, if there is a diverse group of candidates who meet distinct qualifications or if the hiring needs are specific, merging may not provide the best outcome.

Thus, the flexibility of merging allows hiring officials to tailor the selection process to meet their specific staffing goals while still adhering to regulatory standards. This approach promotes effective decision-making in the candidate evaluation process.
