FAR 9.104 Responsibility Determination: Standards for a Responsible Prospective Contractor

Before a federal agency can award a procurement contract, the contracting officer must make an affirmative determination that the winning offeror is a responsible prospective contractor. This is not a formality. FAR 9.103 states the rule directly: “No purchase or award shall be made unless the contracting officer makes an affirmative determination of responsibility,” and in the absence of information clearly indicating responsibility, the contracting officer is required to determine nonresponsibility. The standards that determination runs against — and who else besides the government has to make the same call — are set out in FAR Subpart 9.1, principally FAR 9.104.

This page covers the responsibility determination itself: the seven general standards a contractor must meet, how a contracting officer applies them, the prime contractor’s own duty to determine subcontractor responsibility under FAR 9.104-4, and how this affirmative, judgment-based determination differs from — and sits alongside — the binary SAM.gov exclusions check already covered elsewhere on this site.

Where This Applies: Federal Contracts, Not Federal Grants

FAR 9.104 is part of the Federal Acquisition Regulation, which governs federal procurement contracts — agreements where the government is buying a good or service for its own direct use. It does not govern federal grants or cooperative agreements, which run instead under 2 CFR 200 (the Uniform Guidance). See Grant vs. Contract vs. Cooperative Agreement for how the three instrument types differ, and FAR Part 31 vs. 2 CFR 200 for how the two regulatory tracks diverge on cost principles specifically.

Many research institutions hold both: NIH and NSF funding is overwhelmingly grant-based, but DOD, DOE, and some NIH and NASA work is contract-based, and any institution that operates a federally funded research and development center or holds a direct procurement contract is a FAR-governed prime contractor for that agreement. The distinction matters for this page specifically because FAR 9.104-4 puts a determination duty on that institution, not just on the federal contracting officer — a duty that has no equivalent for a pure grant recipient. Purchases made under a grant instead run through 2 CFR 200 Subpart D procurement standards; see 2 CFR 200 Procurement Standards and the companion Federal Procurement for Research Institutions guide for that decision sequence.

The Seven General Standards (FAR 9.104-1)

To be found responsible, a prospective contractor must, in the contracting officer’s judgment, meet all of the following:

1. Adequate financial resources to perform the contract, or the demonstrated ability to obtain them.
2. Ability to comply with the required or proposed delivery or performance schedule, accounting for existing commercial and government business commitments.
3. A satisfactory performance record. A contractor is not automatically found nonresponsible on performance history alone, and the contracting officer must weigh the relevance of past record to the present acquisition.
4. A satisfactory record of integrity and business ethics.
5. The necessary organization, experience, accounting and operational controls, and technical skills, or the ability to obtain them (which may include subcontractor arrangements).
6. The necessary production, construction, and technical equipment and facilities, or the ability to obtain them.
7. Otherwise qualified and eligible to receive an award under applicable laws and regulations — this is the standard that folds in exclusion status, discussed further below.

FAR 9.104-3 adds two operational points that shape how these standards get applied in practice. First, a prospective contractor doesn’t need to already own everything the contract requires; a firm commitment or explicit arrangement to acquire the needed resources by the time of award is sufficient. Second, a contractor that is or recently has been seriously deficient in contract performance is presumed nonresponsible unless the contracting officer determines the deficiency was properly beyond the contractor’s control or that the contractor has since taken appropriate corrective action — the presumption runs against the contractor, not for it.

Special Standards (FAR 9.104-2)

Beyond the seven general standards, a contracting officer may develop additional, more specific responsibility standards for a particular acquisition or class of acquisitions — typically with input from specialists (technical, financial, or otherwise) appropriate to what’s being procured. Any special standard has to be written into the solicitation and disclosed as a special standard, and it applies uniformly to every offeror, not selectively.

The Prime Contractor’s Duty: Subcontractor Responsibility Under FAR 9.104-4

This is the part of Subpart 9.1 that reaches a research institution directly, independent of whether the institution itself is ever a prime contractor. FAR 9.104-4 states the rule plainly: “prospective prime contractors are responsible for determining the responsibility of their prospective subcontractors.” The same seven standards apply — a prime doesn’t get to invent a looser bar for the vendors and subcontractors it selects to help perform a federal contract.

In practice, this means an institution that holds a FAR-governed prime contract and issues subcontracts or purchase orders under it — to a subcontractor, a supplier, or a consultant performing part of the statement of work — is stepping into a role functionally equivalent to the contracting officer’s, for that specific relationship. The institution’s own contracts or procurement office needs to make and document a responsibility judgment about that party before committing to the subcontract, not simply confirm the party isn’t on an exclusions list and move on. FAR 9.104-4 does preserve a government override: the contracting officer may directly determine a prospective subcontractor’s responsibility when it’s in the government’s interest to do so, which most often shows up as a consent-to-subcontract requirement on higher-risk or higher-value subcontracts written into the prime contract itself.

This subcontractor-responsibility duty is separate from, and should not be confused with, a pass-through entity’s subrecipient risk assessment under a grant. See Subrecipient Risk Assessment and Subaward vs. Subcontract for that parallel-but-distinct grant-side obligation, and Prime Recipient vs. Subrecipient for how the two obligation sets map onto each other’s vocabulary without being interchangeable.

Documentation and Procedure (FAR 9.105)

The contracting officer’s signature on the contract itself legally constitutes the determination that the awardee is responsible — there is no separate certificate. A determination of nonresponsibility, by contrast, has to be made in writing, signed, and placed in the contract file with the basis stated. To reach that determination, contracting officers draw on the offeror’s own representations, government and commercial records, past-performance questionnaires, financial statements, and, where warranted, a preaward survey conducted by another agency.

FAR 9.104-6 specifically requires reviewing the Federal Awardee Performance and Integrity Information System (FAPIIS) before awarding a contract that exceeds the simplified acquisition threshold ($350,000 as of the October 2025 federal acquisition-threshold inflation adjustment; see Simplified Acquisition Threshold (SAT)). FAPIIS pulls together SAM.gov exclusions data with performance and integrity records from the Contractor Performance Assessment Reporting System (CPARS), so a contracting officer — or a prime making its own FAR 9.104-4 subcontractor determination — is expected to consider an offeror’s past performance history, not just its current exclusion status. See FAPIIS, Suspension and Debarment, and Federal Award Integrity Checks for how that system works.

How This Differs From (and Complements) a SAM.gov Exclusions Check

It’s a common assumption that a clean SAM.gov exclusions check satisfies the responsibility question. It doesn’t, and the two checks serve genuinely different purposes:

• The SAM.gov exclusions/debarment check is a binary eligibility gate. It answers one question — is this party currently debarred, suspended, or otherwise excluded from receiving federal awards? — under 2 CFR Part 180 (nonprocurement) or the parallel FAR Subpart 9.4 (procurement) exclusion authority. See Debarment and Suspension Verification (SAM.gov). A party can clear this check completely and still fail a responsibility determination.
• The FAR 9.104 responsibility determination is an affirmative, multi-factor judgment the contracting officer (or the prime, for a subcontractor) has to make even for a party with no exclusion at all: does this specific offeror have the financial capacity, the technical capacity, the equipment, and the integrity record to perform this contract, on this schedule? A vendor can be fully eligible under SAM.gov and still be found nonresponsible — undercapitalized for the contract size, lacking the necessary equipment, or carrying a recent record of seriously deficient performance that hasn’t been remediated.

The two checks are sequenced rather than substitutable: SAM.gov exclusion status is one input folded into standard 7 of FAR 9.104-1 (“otherwise qualified and eligible… under applicable laws and regulations”), and FAPIIS review under FAR 9.104-6 explicitly incorporates SAM.gov exclusions data alongside performance history. A contracting officer, or an institution making its own FAR 9.104-4 subcontractor determination, needs both: confirmation the party isn’t excluded, and a separate, documented judgment that the party can actually perform.

Frequently Asked Questions

Does a clean SAM.gov exclusions check mean a vendor is automatically responsible?

No. A clean SAM.gov check satisfies only one input into one of the seven FAR 9.104-1 standards (legal eligibility). The contracting officer, or the prime contractor for a subcontractor under FAR 9.104-4, still has to make a separate, affirmative judgment on financial capacity, technical capacity, equipment, delivery ability, and performance/integrity record.

Who makes the responsibility determination for a subcontractor?

Generally, the prime contractor does, per FAR 9.104-4, using the same standards a contracting officer would apply. The government contracting officer can step in and make the determination directly when it’s in the government’s interest to do so, which typically appears in the prime contract as a consent-to-subcontract requirement for particular subcontracts.

Does FAR 9.104 apply to purchases made under a federal grant?

No. FAR 9.104 governs FAR-based procurement contracts. Purchases a research institution makes under a federal grant follow the 2 CFR 200 Subpart D procurement standards instead — a related but separately regulated track. See 2 CFR 200 Procurement Standards and Grant vs. Contract vs. Cooperative Agreement.

What happens if a contractor is found nonresponsible?

The contracting officer cannot make the award to that offeror. FAR 9.105 requires the nonresponsibility determination itself to be made in writing, signed, and placed in the contract file with the basis stated — it isn’t a verbal or informal judgment.
