The DD254: What It Is, Why It Matters, and How to Complete It Correctly

What is the highest classification level the contractor will access? (Secret, Top Secret, SCI.)

What specific types of classified information are involved? (COMSEC, Restricted Data, NATO, etc.)

What specific security procedures must the contractor follow? (Storage at own facility vs. government-site-only access.)

RFP phase: draft DD254 in the solicitation lets bidders price security cost (SCIF, COMSEC) into the proposal.

Award: original DD254 authorizes the FSO to initiate clearances and VARs.

Execution: revised DD254 when scope changes (e.g., elevation from Secret to TS access).

Closeout: final DD254 dictates return or destruction of classified material.

1a: FCL level required for the prime — "Top Secret" means you must hold a TS FCL.

1b: Highest level the contractor may store at their own facility. "None" with 1a = TS means employees can hold TS clearances but all classified work occurs at the government site — not a single document at your office.

Lists every facility where classified work will be performed — drives where the FSO must send Visit Authorization Requests.

Yes/No boxes that trigger specific compliance regimes: 10a COMSEC (NSA-mandated procedures), 10e SCI (SSO read-in, SCIF), 10g NATO (specific briefing), 10j CUI (NIST 800-171 and DFARS 7012).

Block 11 dictates how the contractor interacts with classified material — site-only access vs. receive/generate vs. fabricate/store hardware.

Block 13 is narrative security guidance — every Yes in Block 10/11 requires corresponding explanation in Block 13 referencing the applicable Security Classification Guide.

The prime acts as government proxy: you cannot grant a subcontractor more access or higher safeguarding than your own DD254 permits.

Tailor the sub-DD254 to the subcontractor's specific scope — don't pass through unnecessary access.

Upload the executed sub-DD254 to NISS. Verify the sub actually possesses the safeguarding capability before granting it on paper.

The "check everything" CO who marks every Block 10 box "Yes" — push back during the Q&A phase; unnecessary access drives unnecessary cost.

Missing Block 13 narrative for a checked Block 10 box.

Outdated Security Classification Guide references.

Failing to track expiration. DD254s lapse with the contract; option-year extensions require updates. Maintain a DD254 register with 90-day renewal lead time.
