Which document is used in Tier 1 investigations?

The document used in Tier 1 investigations is the SF-85, which is the Standard Form 85, known as the Questionnaire for Non-Sensitive Positions. Tier 1 investigations are generally focused on positions that require access to non-sensitive information and do not involve significant risk to national security. The SF-85 captures the necessary information regarding an individual's background, such as employment history, residence, and criminal activity, to assess their suitability for a position without access to sensitive or classified information.

This makes the SF-85 appropriate for low-risk categories, aligning with the requirements for Tier 1 investigations, which are designed to be less comprehensive than those for higher tiers. The other forms mentioned are not relevant for Tier 1 investigations: the SF-86 is used for higher-level investigations requiring access to classified information, while the SF-84 is intended for security clearance investigations for contractor personnel. The SF-85P is specifically for positions that require a public trust clearance, which again pertains to a different scope of investigation.
