What It Is
Evaluation and source selection is the phase where the government decides who wins. Under FAR Subpart 15.3 an evaluation team assesses each proposal strictly against the factors and significant subfactors stated in Section M — price or cost (always evaluated), past performance (evaluated on most competitive buys above the simplified acquisition threshold), and the technical/non-cost factors — documenting strengths, weaknesses, significant weaknesses, deficiencies, and risk. How the scores translate to a winner depends on the method chosen in planning: under a best-value tradeoff (FAR 15.101-1) the source-selection authority may pay a premium for a superior proposal; under LPTA (FAR 15.101-2) the lowest-priced technically-acceptable offer wins. The agency may award on initial proposals without discussions (if the solicitation said so), or establish a competitive range of the most highly rated proposals under FAR 15.306(c) and hold meaningful discussions, after which it requests final proposal revisions under FAR 15.307. Before award, the contracting officer must find the apparent winner responsible under FAR 9.104; if a small business is found non-responsible, the matter goes to SBA for a possible Certificate of Competency.
What Happens
- The evaluation team scores each proposal against the Section M factors and documents the basis for each rating.
- The CO decides whether to award on initial proposals or to establish a competitive range and hold discussions.
- If discussions are held, offerors in the range address their weaknesses and submit final proposal revisions.
- The source-selection authority makes an integrated best-value (or LPTA) decision and documents it.
- The apparent successful offeror is checked for responsibility (FAR 9.104), with a possible SBA Certificate of Competency for a small business.
Key Activities
| Activity | What It Means |
|---|---|
| Score against Section M | Evaluators rate proposals only on the stated factors and subfactors — unstated criteria cannot drive the award, which is why writing to Section M matters. |
| Establish the competitive range | If discussions will be held, the CO shortlists the most highly rated proposals (FAR 15.306(c)); an excluded offeror can seek a preaward debriefing. |
| Hold discussions & request FPRs | Meaningful discussions raise your weaknesses and deficiencies; the final proposal revision is your last chance to fix them and sharpen price. |
| Determine responsibility | Before award the CO must find the winner responsible (capacity, finances, integrity). A non-responsible small business can seek an SBA Certificate of Competency. |
What It Means for an SDVOSB
Once offers are in, the outcome turns on how the government reads what you already submitted — but two things still matter to an SDVOSB. First, if you make the competitive range and are invited to discussions, treat it as a gift: respond to every weakness and deficiency the contracting officer raises, because anything left unresolved in your final proposal revision will stand. Second, understand the responsibility check — a small business found non-responsible is not simply eliminated; the matter must be referred to the SBA, which can issue a Certificate of Competency that requires award to your firm. If the eventual award looks like the agency departed from the stated Section M factors, that can be a protest ground, so keep a careful record of what was and was not discussed and calendar debriefing and protest deadlines when the decision comes.
What to Do in This Phase
- If invited to discussions, answer every weakness and deficiency raised — leave nothing unresolved in your final proposal revision.
- Respond to clarification requests precisely and on time, without volunteering unrequested proposal changes.
- If found non-responsible as a small business, work the SBA Certificate of Competency process rather than giving up.
- Keep a record of the evaluation exchanges so you can judge whether the process tracked the stated factors.
Watch Out For
- Assuming there will be discussions — the agency can award on initial proposals, so your first offer must be your best.
- Leaving a raised deficiency unresolved in the final proposal revision, which the agency must hold against you.
- Missing that a non-responsibility finding on a small business must be referred to SBA for a Certificate of Competency.

Frequently Asked
What does it mean to be 'in the competitive range'?
Under FAR 15.306(c), when the government decides to hold discussions it establishes a competitive range of the most highly rated proposals based on the evaluation against all stated factors. Discussions are then held only with offerors in that range; those excluded are eliminated from further consideration, are notified, and may request a preaward debriefing. Being in the competitive range is the prerequisite for getting discussions — a real opportunity to fix weaknesses and revise price. Because the agency may also award without discussions when the solicitation allows, you should always submit your initial proposal as if it were your best and final offer.
What is an SBA Certificate of Competency?
A Certificate of Competency (COC) is an SBA determination that a specific small business is responsible — capable of performing a particular contract — issued under FAR Subpart 19.6 and the Small Business Act. If a contracting officer decides not to award to the apparent successful small-business offeror solely because it is found non-responsible (for reasons of capacity, credit, integrity, or perseverance), the matter must be referred to SBA. If SBA issues a COC, the contracting officer must award the contract. The COC process is a critical protection for small businesses, ensuring a responsibility judgment does not quietly eliminate an otherwise-winning SDVOSB without independent review.

The phases of a federal acquisition are tailored to each buy, and the FAR is amended from time to time — always read the actual solicitation and confirm the applicable procedures with the contracting officer, and consult qualified counsel for your specific situation before relying on this.
