The Defense Security Service (DSS) recently produced a brochure entitled, So you need a Security Clearance . . . How to Receive and Maintain Your Security Clearance. This 16 page publication gives a general explanation of security clearances and the process involved in getting one. It also covers individual responsibilities, security issues, and Public Trust determinations, a good primer for the uninitiated.
DSS also has a video entitled, “Tips for e-QIP Submission” (also available in text form) that includes 10 tips for completing the SF-86.
