CPARS

Contractor Performance Assessment Reporting System — the government's database for contractor performance evaluations.

Full Definition

The Contractor Performance Assessment Reporting System (CPARS) is the official government-wide system for documenting and sharing contractor performance evaluations. Governed by FAR 42.1502 and 42.1503, CPARS assessments are required for contracts exceeding the simplified acquisition threshold ($250,000) and are conducted annually for multi-year contracts or at contract completion. Evaluators rate contractors across five standard areas: quality of product or service, schedule adherence, cost control (for cost-type contracts), management and business relations, and small business subcontracting (if applicable). Ratings follow a five-level scale: Exceptional, Very Good, Satisfactory, Marginal, and Unsatisfactory. The contractor receives a draft evaluation and has 30 days to review and submit comments, which become part of the permanent record. CPARS data feeds into the Past Performance Information Retrieval System (PPIRS), which evaluation teams access when assessing proposals.

Why It Matters

CPARS evaluations are visible to all federal agencies and directly impact your ability to win future contracts, making them one of the most valuable assets a government contractor can build. Past performance is a mandatory evaluation factor for most contracts above the simplified acquisition threshold. Proactively manage your CPARS ratings by maintaining open communication with your COR, delivering consistently high-quality work, and meeting every deadline. When you receive a draft CPARS evaluation, review it carefully within the 30-day comment period — if any ratings are lower than expected, submit a professional, fact-based rebuttal with supporting documentation. Request a meeting with the evaluating official if necessary. Track your CPARS evaluations in a central database so you can quickly reference them when preparing past performance volumes. Even Satisfactory ratings can hurt you in competitive procurements where competitors hold Exceptional or Very Good ratings.

Example

A small IT firm completes the second year of a three-year contract providing cloud migration services to the Department of Veterans Affairs. The COR submits a CPARS evaluation rating the contractor Exceptional in quality and schedule, and Very Good in management. The contractor reviews the draft within the 30-day window, notes a factual correction needed in the schedule narrative, and submits comments. The corrected evaluation becomes part of their permanent record in PPIRS, which they cite in two subsequent proposals — winning both based in part on their strong past performance history.
