The primary qualifications for a counterintelligence job are a bachelor's degree and several years of experience. Some employers accept additional education in place of work experience, with a master's or doctorate in a relevant field being preferable. Also, most counterintelligence jobs require a top secret/sensitive compartmentalized information (TS/SCI) security clearance. Getting this security clearance requires employer sponsorship, an exhaustive background investigation, and several interviews. It can take more than a year to get this clearance, so some employers ask you to do other work while you wait. Fulfilling the duties and responsibilities of a counterintelligence job requires experience processing large amounts of data, attention to detail, and excellent analytical skills.
