CPARS & Past Performance Ratings: What Contractors Need to Know

CPARS — the Contractor Performance Assessment Reporting System — is the federal government's official system for evaluating contractor performance after a contract is completed (or at key milestones during longer contracts). Every agency uses CPARS to create a permanent record of how well you delivered.

Contracting officers rate contractors on a 5-point scale: Exceptional, Very Good, Satisfactory, Marginal, and Unsatisfactory. Ratings cover areas like quality of product or service, schedule adherence, cost control, management effectiveness, and small business subcontracting (when applicable). These assessments go into a database that source selection officials reference when evaluating proposals on future contracts.

CPARS is not optional. If you hold a federal contract above the simplified acquisition threshold ($250,000), you will receive a CPARS evaluation. The system is managed by the Department of Defense but used across all federal agencies.

CPARS ratings are not public. Only two groups can access them: government source selection officials evaluating proposals for new contracts, and the rated contractor themselves.

You cannot look up a competitor's CPARS scores. There is no public API, no data feed, and no Freedom of Information Act (FOIA) path to obtain another company's ratings. This is by design — the system is meant to provide candid government assessments without exposing proprietary performance data to the market.

As a contractor, you can view your own ratings by logging into cpars.gov. Access requires an active SAM.gov registration and a valid MPIN (Marketing Partner Identification Number) set during your SAM.gov registration. If you haven't set up CPARS access yet, your SAM.gov administrator can configure it.

While CPARS performance ratings are private, certain integrity-related information is publicly visible through FAPIIS — the Federal Awardee Performance and Integrity Information System. FAPIIS data is partially accessible through SAM.gov entity records and tracks serious performance and integrity issues.

Publicly visible FAPIIS records include: terminations for cause or default, administrative agreements and civil judgments, suspensions and debarments, defective pricing determinations, non-responsibility determinations, and human trafficking violations.

Additional items tracked in FAPIIS but visible only to government officials include: reduced or untimely payments to small business subcontractors, criminal, civil, and administrative proceedings, and other integrity-related actions.

If you see a competitor listed in SAM.gov exclusion records, that's FAPIIS data — not CPARS. The distinction matters because FAPIIS tracks integrity failures, while CPARS tracks routine performance quality.

Past performance is typically weighted 20–30% in source selection evaluations, making it one of the most influential factors after technical approach and price. Some solicitations weight it even higher.

A history of "Exceptional" or "Very Good" CPARS ratings gives a measurable competitive advantage. When two proposals are technically comparable, the contractor with stronger past performance will usually win. Conversely, "Marginal" or "Unsatisfactory" ratings can effectively disqualify a contractor — even if the price is lowest and the technical approach is sound.

New contractors with no CPARS history face a nuanced situation. Federal acquisition regulations require that a lack of past performance be treated as "neutral" — it cannot be held against you. But it also means you can't leverage this evaluation factor the way experienced contractors can. This is one reason why building a track record on smaller contracts is a common entry strategy.

The CPARS evaluation process has built-in safeguards to ensure fairness. Understanding the timeline and your rights as a contractor is essential.

After contract completion (or at annual intervals for multi-year contracts), the assessing official — usually the Contracting Officer's Representative (COR) or contracting officer — drafts an evaluation in CPARS. The evaluation is then reviewed by a higher-level reviewing official within the agency before being sent to the contractor.

Once you receive the evaluation, you have 14 calendar days to review it and submit written comments. If you request it, you can get an additional 14 days (up to 60 days total in some cases). Your comments become a permanent part of the record — source selection officials reviewing your past performance will see both the rating and your response.

If you disagree with a rating and want to discuss it before submitting formal comments, request a meeting with the evaluator within 7 days of receiving the assessment. This is your best opportunity to resolve factual errors or misunderstandings before the evaluation is finalized.

Strong CPARS scores don't happen by accident. The best contractors treat performance documentation as an ongoing process, not something they think about only when the evaluation arrives.

Track your own performance throughout the contract. Keep records of on-time deliveries, cost savings, quality metrics, and positive feedback from government stakeholders. When the CPARS evaluation comes, you'll have evidence to support a higher rating — or to contest an unfair one.

Always respond to every CPARS evaluation, even positive ones. A brief acknowledgment on a good rating reinforces the relationship. On a negative rating, a professional, fact-based response can mitigate the damage when future evaluators read your file.

Use small contracts strategically. Strong CPARS scores on task orders or smaller contracts build the track record you need to compete for larger opportunities. If you're new to federal contracting, pursue contracts where you can deliver exceptional results and build your CPARS portfolio.

Finally, check your CPARS records at cpars.gov at least quarterly. Evaluations can be filed without you noticing if your notification settings aren't configured correctly. Don't let a rating go uncontested because you missed the response window.
