What happens after proposals close
When the proposal deadline passes, an internal evaluation process runs that most bidders never see. The evaluation team receives proposals, a Technical Evaluation Team (TET) scores technical content, a Past Performance Evaluation Team reviews references and CPARS, a Cost/Price Analyst reviews pricing, and the Source Selection Authority (SSA) or contracting officer integrates the findings into a source selection decision.
Technical reviewers score feasibility. Contracting Officers check compliance, price reasonableness, and risk. A technically brilliant proposal with a poorly formatted cost volume or missing SAM registration gets returned without review.
The whole process is governed by FAR Part 15 (negotiated procurement) and the solicitation's Section M (evaluation factors). Understanding how each piece works changes how a small firm writes proposals.
The Technical Evaluation Team

The TET is usually 3-7 government personnel from the program office, technical customers, and subject matter experts. They score each proposal against Section M's stated evaluation factors — technical approach, management approach, staffing, key personnel, whatever the RFP specified.
Scoring is typically done on an adjectival scale: Outstanding / Good / Acceptable / Marginal / Unacceptable, or a color scale (Blue / Purple / Green / Yellow / Red). Each evaluator scores individually, then the team convenes to reconcile scores and produce a consensus evaluation with strengths, weaknesses, deficiencies, and risks.
What makes the TET's job harder is reading 15-30 proposals in a two-to-three-week window. Proposals that are hard to read — dense blocks of text, missing topic sentences, weak headings — are scored worse, not because they are worse but because evaluators cannot find the content. Structure and scannability are evaluation factors even when Section M does not say so.
What strengths, weaknesses, and deficiencies mean
Strength
An aspect that exceeds stated requirements and adds value. Multiple strengths push scores toward Outstanding/Good.
Weakness
An aspect that somewhat increases risk or falls short of a stated requirement. Accumulates to push scores toward Marginal.
Deficiency
An aspect that fails to meet a material requirement. One deficiency typically yields Unacceptable on that factor, which often knocks the entire proposal out.
Risk
An aspect that introduces uncertainty of successful performance — staffing gaps, aggressive schedules, unproven technology.
Proposals lose more often from accumulated weaknesses and one unflagged deficiency than from any single factor.
Past performance evaluation
The Past Performance Evaluation Team reviews proposed references and pulls corresponding CPARS records. CPARS (Contractor Performance Assessment Reporting System) stores government-generated performance ratings across six elements: Quality, Schedule, Cost Control, Management, Small Business Subcontracting, Regulatory Compliance.
Each element is rated Exceptional / Very Good / Satisfactory / Marginal / Unsatisfactory. The team assesses recency (within 3 years preferred), relevance (similar scope and scale), and overall rating. They may call references directly for information not captured in CPARS.
For a new firm without corporate CPARS, past performance evaluation considers:
- Performance by proposed subcontractors (their CPARS records count).
- Performance by key personnel at prior employers, attributed correctly and with permission.
- Commercial past performance — harder to verify, often less weight.
- Absence of past performance as a neutral (not positive, not negative) factor in many solicitations.
Price realism and cost realism
There are two distinct analyses:
- Price reasonableness. Is the proposed price fair to the government? Based on adequate price competition, market research, or comparison to similar contracts. Applies to fixed-price.
- Price realism (when Section M invokes it). Can the work actually be done at this price? A price that is too low may indicate lack of understanding or unacceptable performance risk. Applies to fixed-price when risk shifts on low pricing.
- Cost realism. For cost-reimbursement contracts. Are proposed costs realistic for the work proposed? The government may adjust proposed costs for evaluation ("most probable cost") based on its analysis.
Small firms proposing commercial rates into a federal environment sometimes fail price realism because commercial discounting structures do not map to federal labor categories. Show your basis of estimate and defend the rates against labor market data.
Responsibility determination
Before award, the contracting officer must determine the apparent awardee is a "responsible" contractor (FAR 9.104). Elements:
- Adequate financial resources or the ability to obtain them.
- Ability to comply with delivery schedule.
- Satisfactory performance record.
- Satisfactory integrity and business ethics.
- Necessary organization, experience, accounting and operational controls.
- Necessary equipment and facilities.
- Otherwise qualified and eligible (including small business status verification).
For small firms, the CO typically verifies SAM.gov status, pulls a Dun and Bradstreet report, and may request a recent financial statement. A firm with inadequate financial resources can be found non-responsible, which kills the award. The Small Business Administration Certificate of Competency (COC) process can reverse a non-responsibility determination for small businesses, but it is a several-week process that many COs avoid by choosing a different awardee.
Best value tradeoff vs LPTA
Two source selection methods dominate:
- Best Value Tradeoff (BVT). Technical and past performance are weighted alongside price. Higher-rated proposals can win over lower-priced ones if the technical superiority justifies the price premium. The SSA documents the tradeoff decision in a Source Selection Decision Document.
- Lowest Price Technically Acceptable (LPTA). Lowest price wins among proposals rated technically acceptable. No tradeoff between price and technical quality above the acceptability threshold.
BVT favors firms with strong technical differentiation. LPTA favors firms with low-cost structures. Read Section M carefully — LPTA written as BVT or vice versa changes the strategy entirely. DoD has largely moved away from LPTA for complex services; civilian agencies still use it for commodity-like work.
What actually decides wins
From observable patterns across dozens of small business awards:
- Strong, relevant past performance is the single biggest discriminator at BVT source selections.
- Credible technical approach demonstrating specific methodology and tools (not generic capability narrative) wins technical factor.
- Named, qualified key personnel with relevant resumes build confidence. Unnamed "TBD" staffing reads as risk.
- Defensible pricing — not the lowest, but justifiable and realistic — avoids the price realism trap.
- Compliance with Section L — format, page limits, section ordering — ensures the proposal is actually read.
What small firms get wrong
- Treating past performance as a formality. It is usually the heaviest weighted non-price factor.
- Assuming LPTA when the RFP says BVT (or vice versa). Read Section M.
- Racing to the lowest price. Price realism catches thin pricing; you lose twice — reputation and award.
- Writing long proposals assuming length signals thoroughness. TETs score clarity, not density.
- Proposing unnamed key personnel or "we'll hire to this skill set." TETs treat unnamed staffing as risk.
Bottom line
Federal source selection is a structured process executed by real people reading many proposals in a short window. The firms that win consistently optimize for evaluation mechanics: scannable structure, specific technical content, relevant past performance, defensible pricing, compliance with Section L. The firms that lose optimize for length or marketing polish. Understanding what the TET, Past Performance Team, and Cost Analyst actually do changes how every page of a proposal is written.
Frequently asked questions
A Technical Evaluation Team (3-7 government technical personnel), a Past Performance Evaluation Team, a Cost/Price Analyst, and a Source Selection Authority. Each has a defined scope under FAR 15 and the solicitation's Section M.
Contractor Performance Assessment Reporting System. Government-generated performance ratings across Quality, Schedule, Cost Control, Management, Small Business Subcontracting, and Regulatory Compliance. Stored for 3 years and pulled during past performance evaluation.
An analysis of whether a proposed price is realistically executable. Invoked in Section M for fixed-price when low prices shift performance risk. Too-low prices can be found unrealistic and proposals downgraded accordingly.
A pre-award finding under FAR 9.104 that the apparent awardee has adequate financial resources, performance record, organization, and eligibility to perform. Small business firms found non-responsible can seek a COC from SBA.
BVT dominates for complex services, including almost all AI work. LPTA is still used for commodity-like services. Section M states the method; read it carefully.
Proposed subcontractor CPARS, key personnel prior-employer attribution with permission, and commercial past performance. Absence of past performance is usually a neutral factor, not negative — but puts pressure on technical and price factors to win.
