How CPARS and past performance work in federal contracting.

What it is. CPARS — the Contractor Performance Assessment Reporting System — is the government’s web-based library of contractor “report cards.” For each contract or order, the agency records an evaluation of how you performed over a set period, usually a year. Since October 1, 2010, federal agencies have been required to collect this past-performance information through CPARS under Federal Acquisition Regulation (FAR) Subpart 42.15.

Why it follows you. These evaluations are not filed and forgotten. Contracting officers on future solicitations pull your past-performance record and weigh it in source selection — agencies use the CPARS information for three years after the work is complete (six years for construction and architect-engineer contracts). A strong record helps you win the next award; a poor one, left unanswered, quietly costs you bids you never hear about.

Why it matters for NYC firms moving into federal work. If you are stepping up from City and State contracts into federal ones — often as a certified small business or subcontractor to a prime — CPARS is the layer that has no City equivalent. The first federal job you deliver starts a record that shapes every bid after it, so it is worth understanding before you sign, not after.

An assessing official — usually the contracting officer or a program manager — prepares an evaluation at least once a year, and again when the work is finished. The rules require it to reflect objective facts backed by contract performance data, not opinion, and you are rated across several areas that typically include:

• Quality of the product or service delivered.
• Schedule — whether you hit the timeline.
• Cost control — staying within the negotiated price where applicable.
• Management and responsiveness, including key personnel.
• Small business subcontracting, where a plan applies.

Each area gets one of five ratings: Exceptional, Very Good, Satisfactory, Marginal, or Unsatisfactory. “Satisfactory” is a genuine pass — it means you met the requirements of the contract. Anything below it signals problems a future buyer will notice, and each rating is supposed to carry a written narrative explaining it.

The narrative matters as much as the checkbox: it is the part a future contracting officer actually reads. Concrete, accurate detail — on both sides — is what makes the record useful rather than a bare grade.

The clock. When an evaluation is ready, CPARS sends you an automatic notification, and you have up to 14 calendar days from that notice to review it and submit comments, a rebutting statement, or additional information. Your comments are recorded alongside the rating — so if an assessment is unfair or incomplete, this is your one built-in chance to put your side on the permanent record.

If you disagree. A rating is not necessarily final. When you and the agency disagree, the rules require a review at a level above the contracting officer before the evaluation is closed out. The agency still makes the ultimate call, but a documented, factual rebuttal is what a future buyer sees next to the score — and what a review official weighs.

How to protect your record. Register for a CPARS account at cpars.gov and keep your point-of-contact email current so notifications actually reach you — a missed email is a missed 14-day window. Keep your own performance file as you go (delivery dates, acceptance records, correspondence), so if a rating is off you can answer with facts, fast. Then put your strongest completed jobs to work: past performance is exactly what a capability statement and a competitive proposal are built on.

Watch this space. When the FAR’s past-performance rules or the CPARS process change — and the FAR is being rewritten across many parts in 2026 — we will cover what it means for small businesses in this digest.
