CID Agent candidates must be currently serving as an enlisted active duty Marine between the grades of E-5 through E-9 or WO1 to CWO5. Civilian CID Agents must be employed in the government schedule (GS) 1811 series as a criminal investigator. All CID Agents must be able to obtain and maintain a Top Secret security clearance. Marine candidates must possess a GT score of 110 or higher, have normal color vision. Both Marine and civilian agents must meet Marine Corps physical fitness standards. Prospective Marine Corps CID agents are sent to the U.S. Army Military Police Schools (USAMPS) to attend the U.S. Army CID Special Agent Course (CIDSAC) at Fort Leonard Wood, MO, and must complete six months on-the-job training. Civilian CID agents either attend CIDSAC, or the Criminal Investigative Training Program (CITP) at the U.S. Department of Homeland Security’s Federal Law Enforcement Training Center (FLETC) at Glynco, GA. Marine Corps CID agents may later return to USAMPS or FLETC to attend advanced or specialized training as may be directed.
