CPARS

FAR subpart 42.15 requires agencies to evaluate contractor performance on contracts above set thresholds, generally at least annually and at completion. The assessing official rates evaluation areas such as quality, schedule, cost control, management and small business subcontracting, using a five-level scale from Exceptional to Unsatisfactory, with a narrative.

The contractor is notified and has a set period to comment, rebut or provide more information before the evaluation becomes final. Finished evaluations flow to the government's past performance records, which source selection teams consult.

When a solicitation evaluates past performance, evaluators check what you claim against CPARS. A strong narrative backed by Very Good or Exceptional ratings is persuasive; a write-up that contradicts a weak CPARS rating hurts credibility.

Manage CPARS during the contract, not after: keep the contracting officer's representative informed of results, respond to every draft evaluation within the comment period, and ask for corrections with evidence. State and local agencies use their own vendor performance systems, so the name and process vary by jurisdiction.

Because CPARS is the record evaluators trust most, a short, consistent narrative across your evaluations helps. When an evaluation is coming due, send the assessing official a factual summary of what you delivered in the period: milestones met, metrics, problems solved and any recognition from the customer. Officials are busy, and a well-organized summary makes it easier to write a specific, positive narrative. Keep copies of every final evaluation with your past performance records so proposal writers can quote it accurately.
