Contractor Performance Assessment Reporting System (CPARS)

Definition

The Contractor Performance Assessment Reporting System (CPARS) is the governmentwide system of record for past performance ratings on contracts over the simplified acquisition threshold. The Contracting Officer completes CPARS annually for active contracts and at final close-out. Ratings cover categories like quality, schedule, cost control, management, and small-business subcontracting, using a 5-point scale from Unsatisfactory to Exceptional. Finalized ratings flow into PPIRS and are available to evaluators on future competitions.

Why It Matters

CPARS is the long tail of every federal contract you win. Ratings follow you for years and are routinely cited by evaluators as a decisive factor in close competitions. A single negative CPARS can effectively disqualify a firm from similar work for three to five years. Treat CPARS as a proactive program: weekly performance tracking, pre-CPARS 'dry runs' with the COR and CO, and timely contractor rebuttals on any factual errors are all essential practices.

Example

At year-end CPARS, a COR drafts a 'Satisfactory' rating for cost control because a modification was required. The contractor submits a 60-day factual rebuttal showing the modification was caused by a government-directed change, not contractor inefficiency. The CO updates the rating to 'Very Good,' which helps the firm win a re-compete the following year.
