The Average Salary of an OPM Investigator

Growth Trends for Related Jobs


Since 1953, the Office of Personnel Management (OPM) has been responsible for managing the security clearance program for federal employees. The OPM background investigators conduct inquiries into an applicant’s past, including a criminal background and credit check, to ascertain whether the applicant is a suitable candidate for the position. Certain sensitive positions may require the investigator to interview an applicant’s family, neighbors or friends. Investigators belong to the 1810 classification, with salaries based on the general schedule (GS) system of pay grades.

Advancing to Next Pay Grade

Investigators at the GS-5 level must have a bachelor’s degree or three years of experience, with at least one year of job duties equivalent to a GS-4 or above. To advance to a GS-7, the investigator must have at least one year of graduate school, “superior academic achievement” or one year as a GS-5. A GS-9 must have a master’s degree, or two academic years of graduate or law school, or one year’s experience as a GS-7. To advance to a GS-11 pay grade requires one year of GS-9 experience, a doctoral degree, or three academic years of graduate school. Advancement to grades GS-12 and above require one year of experience at the previous grade.
