What It Is
The Contractor Performance Assessment Reporting System, CPARS, is the governmentwide system in which federal agencies document formal evaluations of how contractors performed on their contracts. Hosted by the Department of Defense for the entire government, CPARS is where contracting officers and program officials record a Contractor Performance Assessment Report (a CPAR) rating a firm on factors such as quality, schedule, cost control, management, and regulatory compliance, typically at least annually and at contract completion. Under FAR Subpart 42.15, agencies must prepare these evaluations for contracts above specified thresholds, and the resulting past-performance information is made available governmentwide for use in future source selections (the retrieval function once branded PPIRS is now integrated with CPARS). The contractor has the right to review each evaluation and submit comments before it is finalized. Because past performance is a standard evaluation factor, CPARS ratings directly shape a firm's competitiveness on future bids.
When You Touch It
- During performance — a CPAR is typically recorded at least annually, so evaluations accrue as you perform.
- At the comment window — you have the right to review and respond to each evaluation before it is finalized.
- At contract completion — a final evaluation captures overall performance on the contract.
- Before you bid — your CPARS history is the past-performance record a future source-selection team will read.
Key Features
| Feature | What It Means |
|---|---|
| The government's past-performance record | CPARS holds the formal evaluations future source-selection teams read when they score your past performance. |
| Governmentwide and integrated retrieval | Ratings recorded by one agency are available to evaluators across the government (the old PPIRS retrieval is now part of CPARS). |
| You get to comment | The contractor may review each evaluation and submit comments before it is finalized, so a rating is not one-sided. |
| Rated on standard factors | Evaluations cover quality, schedule, cost control, management, and compliance — the dimensions that recur in source selection. |
What It Means for an SDVOSB
For an SDVOSB, CPARS is where today's performance becomes tomorrow's competitiveness — a strong record is one of the few things that lets a small firm beat larger competitors on best-value awards. Two habits matter. First, treat every contract as a future CPAR: deliver, document, and keep the contracting officer informed, because these ratings follow you into every subsequent source selection. Second, use your comment rights — read each evaluation carefully and respond to anything inaccurate or unfairly negative before it is finalized, since an unrebutted weak rating can quietly cost you awards for years. New firms without a CPARS history are not shut out: in negotiated buys, a lack of relevant past performance must be rated neutral, so early clean CPARs are worth building deliberately, including through subcontract and joint-venture performance that can be credited to you.
Watch Out For
- Skipping your comment window — an inaccurate or unfair rating left unrebutted becomes part of your permanent record.
- Assuming no history is fatal — in negotiated buys a lack of relevant past performance must be rated neutral, not negative.
- Ignoring interim CPARs — evaluations accrue during performance, not just at the end, so watch for them throughout.
- Forgetting subcontract/JV performance counts — relevant work performed as a sub or in a JV can support your past-performance case.

Frequently Asked
What is CPARS?
CPARS, the Contractor Performance Assessment Reporting System, is the governmentwide system where federal agencies record formal evaluations of how contractors performed on their contracts. Hosted by DoD for the whole government, it captures Contractor Performance Assessment Reports (CPARs) rating firms on factors like quality, schedule, cost control, and management. Under FAR Subpart 42.15, these evaluations are prepared for contracts above certain thresholds and made available governmentwide for use in future source selections. Contractors can review and comment on each evaluation before it is finalized.
Can I respond to a CPARS evaluation I disagree with?
Yes. The contractor has the right to review each CPARS evaluation and submit comments before it is finalized. If you believe a rating is inaccurate or unfair, you should use that comment window to document your response, because the evaluation — and your comments — become part of the past-performance record that future source-selection teams read. Failing to respond leaves a weak rating unrebutted in your permanent record.
What if my SDVOSB has no CPARS history yet?
A lack of past-performance history is not disqualifying. In negotiated procurements under FAR Part 15, an offeror without a record of relevant past performance must be given a neutral rating on that factor — it cannot be scored favorably or unfavorably. That said, building an early, positive CPARS record is valuable, so newer SDVOSBs often pursue smaller contracts, subcontracts, or joint ventures where relevant performance can be credited toward their past-performance case.
