which of the following is required to access classified information

To access classified information (in the U.S. national security context), a person must have all of the following: an appropriate security eligibility/clearance, a demonstrated need-to-know, and a signed nondisclosure agreement (typically SF 312).

Core requirements

  • Security eligibility/clearance at or above the classification level of the information (for example, Confidential, Secret, or Top Secret), granted after a favorable background investigation and adjudication.
  • Need-to-know , meaning the person must require that specific information to perform official duties; clearance alone is not enough.
  • Signed nondisclosure agreement (SF 312) acknowledging legal obligations to protect classified information and not disclose it without authorization.

How it’s often tested in questions

Many training or exam items phrase this as “Which of the following is required to access classified information? (Select all that apply.)” with correct choices being:

  • National security eligibility/security clearance at the appropriate level
  • Need-to-know for the specific information
  • Signed SF 312 (Classified Information Nondisclosure Agreement)

Approval from an Original Classification Authority (OCA) is generally not listed as a basic individual access requirement in these questions; the focus is on clearance, need-to-know, and the nondisclosure agreement.

In short: eligibility + need‑to‑know + signed SF 312 are all required before accessing classified information.
