Federal Source Selection & Evaluation Methods Explained for SDVOSBs

Winning a set-aside is not just about submitting a proposal — it is about understanding how the government will grade it. Is the buy a best-value tradeoff that rewards a stronger approach, or an LPTA where the lowest acceptable price wins? Will there be a competitive range and discussions, or award on initial proposals with no second chance? These plain-English pages take one source-selection concept at a time — what it is, when it applies, the key features, a how-to-win checklist, and the SDVOSB-specific angle — each tied to the controlling FAR provision and cross-linked to the glossary, solicitation types, clauses, contract types, calculators, and how-to guides.

Selection Methods

Tradeoff — Best-Value TradeoffThe source-selection process that lets the government pay a higher price for a better proposal — where technical merit, past performance, and other factors can outweigh price.
LPTA — Lowest-Price Technically-AcceptableThe source-selection process where award goes to the lowest-priced proposal that meets the stated technical acceptability standards — no credit, and no premium, for exceeding them.

Evaluation Factors

Factors — Evaluation Factors & SubfactorsThe stated criteria — and their relative importance — against which the government evaluates proposals; price or cost and past performance are evaluated in every negotiated competition.
Technical — Technical / Non-Cost EvaluationThe assessment of the quality of your technical and management approach against the stated non-cost factors — graded for merit under tradeoff, or pass/fail under LPTA.
Past Perf — Past Performance EvaluationThe government's assessment of how well you performed similar work before — recency, relevance, and quality — and how a newer SDVOSB with no record is treated.
Price Analysis — Price & Cost AnalysisHow the government tests whether your price is fair and reasonable, and — on cost-reimbursement and some fixed-price work — whether it is realistic for the work proposed.

The Evaluation Process

Comp Range — The Competitive RangeThe shortlist of the most highly rated proposals the contracting officer establishes when discussions will be held — make this cut, or you are out of the running.
Discussions — Discussions & Final Proposal RevisionsThe negotiations the government holds with offerors in the competitive range — meaningful exchanges about deficiencies and weaknesses — followed by a request for final proposal revisions.
No Discussions — Award Without DiscussionsWhen the solicitation says so, the government can award on initial proposals with no discussions — so your first proposal has to be your best and final offer.
Orals — Oral PresentationsWhen the solicitation calls for them, a live presentation — often by your key personnel — that substitutes for or supplements written proposal sections and is scored as part of the evaluation.

Award & Beyond

Responsibility — Responsibility Determination & Certificate of CompetencyBefore award the contracting officer must find the apparent winner 'responsible' — capable and reliable — and if a small business is found non-responsible, the SBA's Certificate of Competency process can override that finding.
Debrief — DebriefingsYour right, on a negotiated competition, to a government explanation of how your proposal was evaluated — feedback that sharpens your next bid and starts the clock on a possible protest.

Know how you will be scored, then price to win

Whether the buy is a best-value tradeoff or LPTA decides whether quality or price wins. The win-probability estimator gauges the field, the price-to-win calculator sets your number — and the weekly Brief turns your certification into a stream of set-aside opportunities to bid.
