What to request, what to expect, and how a debriefing shapes the protest clock.
Last reviewed on May 12, 2026.
A debriefing is a structured exchange between the agency and an offeror after the source selection decision. The agency explains why the offeror was not selected (or, in pre-award cases, why a proposal was eliminated from competition). For the offeror, the debriefing serves three purposes: understanding what to improve on the next pursuit, gathering information that informs a possible bid protest, and meeting the timing condition that extends the protest filing window.
Skipping a debriefing — when you are entitled to one — typically forfeits the most useful learning opportunity in the entire procurement cycle and may shorten your protest window.
In a negotiated procurement under FAR Part 15, an unsuccessful offeror is entitled to a debriefing on request. The request must be submitted within 3 days after the offeror receives notice of contract award. The agency must conduct the debriefing as soon as practicable.
Required debriefings cover: significant weaknesses or deficiencies in your proposal, the overall evaluated cost or price and technical rating of your proposal and the awardee, past performance information used in the evaluation, the rationale for award, and reasonable responses to relevant questions about source selection procedures.
DoD provides "enhanced" debriefings on contracts above $10 million (lower thresholds for certain small businesses). Enhanced debriefings allow the offeror to submit follow-up written questions within 2 business days of receiving the debriefing, with agency answers due within 5 business days.
The enhanced framework extends the protest filing window — the protest clock effectively runs from receipt of the agency's responses to follow-up questions rather than from the original debriefing date.
When the agency eliminates an offeror from the competitive range before award, the offeror may request a pre-award debriefing. These debriefings address why the proposal was eliminated, not the eventual award decision.
Pre-award debriefings are narrower in scope than post-award debriefings but valuable for understanding evaluator concerns early, when the offeror may still influence its position on related opportunities.
The debriefing rules carefully balance disclosure to the unsuccessful offeror against protection of the awardee's proprietary information. The agency must disclose:
The agency must not disclose:
Where the line falls is often disputed. Agencies vary in how generous they are with detail. Most allow more disclosure when the unsuccessful offeror asks specific, focused questions rather than blanket "tell me more" prompts.
The timing relationship between debriefing and protest is the single most important procedural piece. The relevant rules:

Avoid asking the agency to compare your proposal directly to the awardee's technical content — the agency cannot answer.
It depends on the procedures used. The debriefing entitlements in FAR 15.505 and 15.506 apply to negotiated procurements under FAR Part 15. Awards made under simplified acquisition procedures — where many RFQs sit — carry a lighter obligation: the agency provides a brief explanation of the basis for award rather than a full debriefing. You can still ask, and many contracting officers will tell you more than they must, but the entitlement is not the same.
A required debriefing is the one you are entitled to on timely request under FAR Part 15, covering the evaluation of your own proposal, the rationale for award, and the awardee's price. An enhanced debriefing is a DoD-specific process under DFARS 215.506-70 that additionally allows the offeror to submit written questions within two business days of receiving the debriefing, with the agency's answers due within five business days — and the debriefing is not considered concluded until those answers are delivered, which keeps the protest clock open.
Within three days of receiving notice of award for a post-award debriefing. This is the deadline that matters most, because it also governs your protest options: the automatic stay at GAO depends on filing within five days of a required debriefing, so a late debriefing request can forfeit the stay even where you have strong protest grounds. Diary the request the day you receive the award notice.
The evaluation of your proposal's significant weaknesses and deficiencies, the overall evaluated cost or price and technical rating of your proposal and the awardee's, the overall ranking of offerors where one was developed, a summary of the rationale for award, and reasonable responses to relevant questions about whether procedures were followed. The agency need not give you a point-by-point comparison against other offerors, and it will not disclose their proprietary information.
