Contractor Performance Assessment Reporting System (CPARS)

The Contractor Performance Assessment Reporting System (CPARS) is the US federal government's official platform for documenting and sharing contractor performance evaluations, used by source selection officials to assess past performance when awarding new contracts.

What is CPARS?

CPARS is managed by the Naval Sea Systems Command on behalf of all federal agencies and is mandated by FAR Part 42.15 for contracts above the simplified acquisition threshold. After a contractor completes a period of performance, the government's Contracting Officer's Representative (COR) enters a structured evaluation across five dimensions: quality of deliverables, adherence to schedule, cost control (for cost-type contracts), management responsiveness, and small business subcontracting performance.

Each dimension receives an adjectival rating: Exceptional, Very Good, Satisfactory, Marginal, or Unsatisfactory. The evaluator also writes a narrative explaining the rating with specific examples. The contractor receives the draft evaluation and has 30 days to review and submit a formal response before the assessment is finalized. Once finalized, evaluations are stored in CPARS and made accessible to source selection officials through the Past Performance Information Retrieval System (PPIRS) - a read-only view used during proposal evaluations.

A critical fact: CPARS evaluations are not public. Only the government and the rated contractor can view the evaluations. Competitors cannot search a company's CPARS record. This makes past performance a significant source of information asymmetry - contractors with strong ratings hold an advantage that is invisible to competitors but highly visible to evaluators. Ratings are typically completed annually for multi-year contracts and within 120 days of task order or contract completion.

Why CPARS matters for government contractors

CPARS ratings directly influence proposal scores in source selections that evaluate past performance. An "Exceptional" rating on a relevant prior contract can be a decisive differentiator in a best-value competition. A "Marginal" or "Unsatisfactory" rating on any evaluated contract remains visible to proposal evaluators for up to three years. Contractors who proactively manage their CPARS evaluations - documenting achievements, meeting with the COR before evaluation periods close, and responding formally to any unfavorable narratives - protect their competitive position on future bids.

Example

A mid-size IT services firm completes the base year of a $12 million DHS cloud migration contract. Sixty days before the evaluation period closes, the program manager meets with the COR to review deliverable completion rates, milestone achievements, and cost performance. The COR drafts ratings of Exceptional on quality and management, Very Good on schedule, and Satisfactory on cost control. The contractor submits a formal response adding context on the two schedule delays - both caused by government-furnished information arriving late. The final record, accessible via PPIRS, becomes a key asset cited in the firm's next three proposal past performance volumes.

Frequently Asked Questions

How do I access my company's CPARS evaluations?

Contractors can view their own CPARS evaluations by logging into the CPARS system at cpars.gov using their government-issued credentials. Your company's Focal Point (an administrator role) can set up access for program managers and proposal staff. You cannot view evaluations for other companies.

What happens if I disagree with a CPARS rating?

Within the 30-day review window, you can submit a formal contractor response that becomes a permanent part of the record. You can dispute inaccurate facts, provide additional context, or note that delays were caused by government actions. While you cannot change the government's rating, a well-written response that addresses specific concerns can mitigate the impact of a lower rating in future source selections.

How long do CPARS ratings stay on record?

CPARS evaluations remain accessible in PPIRS for three years from the date of completion for contracts and six years for delivery orders and task orders. After that period, they age out of the system. Contractors pursuing long-term growth in the federal market should treat every performance period as a strategic investment in future wins.

Do all contracts require CPARS evaluations?

CPARS evaluations are required for contracts at or above the simplified acquisition threshold ($250,000) for most contract types. Contracts below that threshold, purchase orders, and some commercial item contracts may be exempt. Contracting officers retain discretion to complete evaluations on smaller contracts when performance is particularly noteworthy or problematic.
