As a contract background investigator, you assess the employment and personal histories of individuals seeking employment or appointment in an agency or organization. Depending on your client and the case, your research may be more or less rigorous, and what defines a potential concern is likewise subject to some change. For instance, those seeking employment in federal law enforcement may be subject to an added layer of scrutiny as compared to those working in corporate security. Regardless, you look through public sources to determine an individual’s employment history, their prior duties and responsibilities in those positions, and you may look through social media accounts or other personal sources for additional character reference.
