Which phase follows the initial screening in the Special Agent selection process?

The phase that follows the initial screening in the Special Agent selection process is the background investigation. This step is crucial as it involves a comprehensive examination of a candidate's personal history, including criminal records, employment history, financial records, and personal references. A thorough background investigation ensures that candidates meet the necessary standards of integrity and reliability expected of a Special Agent.

This phase is integral to evaluating a candidate's suitability for a position that requires a high level of trust, confidentiality, and ethical behavior. The information gathered during this stage helps assess whether the candidate is a good fit for the role and aligns with the values of the agency.

In contrast, the other options refer to different elements of the selection process that occur at varying times or are prerequisites for moving forward in the application.
