What documentation is necessary for a security clearance?

The necessary documentation for obtaining a security clearance includes the SF-86 form, which is the Questionnaire for National Security Positions. This form collects detailed information about the individual's background, including their personal history, employment record, and any potential security risks.

Additionally, a thorough background investigation is conducted to verify the information provided in the SF-86 and assess the individual's trustworthiness and reliability. This investigation may include checking criminal records, financial history, and interviews with references, family, and associates. The combination of the SF-86 form and the background investigation is crucial to ensure that only individuals who are deemed suitable and reliable for accessing classified information are granted a security clearance.

Other options, while they may be beneficial in various contexts, do not encompass the complete set of documentation and assessment required specifically for a security clearance. For example, a diploma and reference letter may support an application but are not sufficient as the main documents.
