A government security clearance is a determination by the U.S. government that an individual is eligible to access classified information. The process of applying for a security clearance can be lengthy and complex, but it is essential for anyone who wishes to work in a position that requires access to classified information.
There are three main types of security clearances: confidential, secret, and top secret. The type of clearance that an individual needs will depend on the level of classified information that they will be accessing. To apply for a security clearance, an individual must submit a completed Standard Form 86, Questionnaire for National Security Positions, to the appropriate government agency. The SF-86 is a lengthy form that asks for detailed information about an individual’s personal history, education, employment, and foreign contacts.
