NCIS Special Agent case studies

NCIS Special Agent · Put your knowledge to work in context.

The NCIS Special Agent hiring process is the entry route into the Naval Criminal Investigative Service, the federal law enforcement agency that investigates felony-level crime tied to the U.S. Navy and Marine Corps. It is built for people seeking a sworn federal special agent career, not for current agents pursuing a promotion, and it blends written testing with performance-based stages: a writing sample, structured and panel interviews, an oral board, a physical fitness assessment, medical and polygraph screening, and a background investigation. The knowledge tested spans criminal investigation and case management, federal criminal law and procedure, investigative interviewing, evidence and crime scene handling, report writing, logic and problem solving, situational judgment and integrity, the naval and military justice context, and digital evidence awareness. The NCIS Special Agent case studies are 5 cases and about 3,345 words.
