Past performance is how the government decides whether to trust you with its money. Before it awards a competitive contract, it looks at what you've done before — and whether you did it well. Get rated well and it's an asset that compounds across every proposal you write. Get rated poorly, or have no record at all, and you're fighting uphill on every competitive source selection.
The mechanics are not obvious, especially if you've spent most of your federal career as a subcontractor. Here's how it actually works.
In a competitive acquisition, past performance is a mandatory evaluation factor under FAR 15.305(a)(2). You submit references — contracts similar in scope, size, and complexity to what's being solicited — and the government assesses how those contracts went. That assessment, combined with a judgment about how relevant the prior work is, becomes your past performance rating for the competition.
"Recent" typically means the last three years, sometimes five for large or complex acquisitions. The RFP will tell you the lookback period. Don't submit references outside it without checking — evaluators are allowed to disregard them.
"Relevant" is where the analysis gets interesting. A $300,000 cybersecurity assessment contract is relevant experience for a $400,000 follow-on assessment. It carries almost no weight when you're bidding on a $25M cyber operations IDIQ. Size and complexity both matter, and source selection panels can downgrade relevance even when the technical subject matter matches perfectly.
The government's primary tool for capturing contractor performance is CPARS — the Contractor Performance Assessment Reporting System, at cpars.gov. Under FAR 42.1502, contracting officers are required to submit CPARS evaluations when contracts meet the applicable threshold:
| Contract Type | Reporting Threshold |
|---|---|
| Services (including IT services) | $250,000 |
| Supplies | $250,000 |
| Construction | $750,000 |
| Architect-Engineer | $30,000 |
| Operation & Maintenance | $250,000 |
The CO evaluates performance across several dimensions — quality of product or service, schedule, cost control (on cost-type contracts), management or business relations, and small business subcontracting compliance where applicable. Each dimension gets a rating from this scale:
| Rating | What It Signals |
|---|---|
| Exceptional | Significantly exceeded all requirements; addressed problems with highly effective solutions |
| Very Good | Exceeded requirements; minor problems resolved with effective solutions |
| Satisfactory | Met requirements; some minor problems, resolved adequately |
| Marginal | Did not meet some requirements; recovery action was only marginally effective |
| Unsatisfactory | Did not meet requirements; little or no corrective action |
| Not Rated / N/A | Not applicable for a given dimension |
When the CO submits a rating, you receive notification and have a review period — typically 14 days — to respond. Your comments become part of the permanent record that future source selection boards will see. If a rating is factually wrong (the CO noted a late delivery on a date when the delivery was actually on time), push back in writing. A well-documented contractor comment on a marginal rating can significantly soften how evaluators interpret it.
Here's the thing most small subs don't realize until they try to write their first prime proposal: CPARS tracks prime contractors, not subcontractors. If you've spent five years doing excellent work as a sub, none of that shows up in CPARS under your UEI. It shows up — if at all — in the prime's rating.
The practical consequences:
The RFP specifies what it will accept. When it doesn't give exhaustive guidance, the general hierarchy is:
The gold standard. If you have prime contracts above the reporting threshold, you have CPARS records. Log into cpars.gov with your government credentials to review them before any proposal effort — don't discover a bad rating during proposal prep.
No CPARS record, but you can still submit subcontract past performance with documentation from the prime. This means a letter or completed Past Performance Questionnaire (PPQ) from the prime's contracting or program manager, describing your work, value, period of performance, and their assessment. Some solicitations have a standard PPQ form; others accept free-form letters.
Some solicitations explicitly allow commercial past performance for companies transitioning from the private sector. Others don't. When it's ambiguous, ask in the pre-proposal Q&A whether commercial work is acceptable — get the answer in writing as an official solicitation amendment.
A small number of solicitations accept past performance citations for key individuals rather than the company — relevant when the company is new but the personnel have deep relevant histories with previous employers. This is more common in professional services and R&D acquisitions than in standard services or IT.
CPARS handles performance ratings. FAPIIS — the Federal Awardee Performance and Integrity Information System, at fapiis.gov — handles adverse information: terminations for default, administrative agreements, suspensions and debarments, and certain criminal and civil proceedings. Evaluators check both systems.
A record in FAPIIS is not automatically disqualifying, but it triggers disclosure obligations and adds friction to every award. If you have a FAPIIS record, know exactly what it says and be prepared to address it proactively in proposals — evaluators respect contractors who acknowledge issues and describe corrective actions over those who appear to have hoped nobody would notice.
For DoD work, also check SPRS (Supplier Performance Risk System). This replaced PPIRS for DoD assessments and includes cyber risk scores (CMMC-related) alongside performance data.
The path out of a thin past performance position is straightforward, just slow:
Contracts below $250,000 don't require CPARS entries, but COs can submit them voluntarily — and many do for high-performing small businesses. Even if they don't, you have a prime contract reference to cite. Micro-purchase and simplified acquisition threshold work is a real on-ramp.
The moment a subcontract ends, request a PPQ from the prime's PM or CO. Don't wait — institutional memory fades fast, people move on, and email trails get lost. A completed PPQ sitting in your past performance file is worth more than a vague promise that someone will write you a letter when you need it.
When you're performing as a sub, document everything: on-time delivery rates, acceptance letters, award fees, client feedback emails. This becomes the factual backbone of a subcontract reference. "Delivered all 47 reports on or ahead of schedule across a 24-month period" is a better reference than "performed IT support services."
COs are required to file CPARS evaluations but often don't, especially on smaller contracts. If a contract closes and you haven't received a CPARS evaluation after 120 days, it's entirely appropriate to contact the CO or their supervisor. A missing CPARS rating is a lost asset.
Check your records now — not during proposal prep. Log into cpars.gov, review every evaluation on file, and respond to anything inaccurate. Run your UEI through FAPIIS. Pull any PPQs from subs you've worked under in the last three years before those relationships get stale.
If you're two years into federal work with no prime contracts and a thin sub record, the answer isn't a better proposal — it's different pipeline strategy. Target set-aside contracts small enough to win outright, win one, deliver well, and get the CPARS entry. That single record changes your competitive position across every proposal for the next three years.
Past performance is the one evaluation factor you can't write your way out of. Build it in the field.
Your next PPQ starts with identifying primes actively winning in your NAICS space. PrimeFinder searches SAM.gov registrations and USASpending award data to surface the right prime contacts — before you need them for a reference.
