Contractor Performance Assessment Reporting System (CPARS) is a web-enabled application that collects and manages the library of automated contractor assessment data.  A Contractor Performance Assessment Report (CPAR) assesses a contractor’s performance and provides a record, both positive and negative, on a given contract during a specific period of time.  Each assessment is based on objective facts and supported by program and contract management data.  This data includes:

  • Cost Performance Reports
  • Customer comments
  • Quality reviews
  • Technical interchange meetings
  •  Financial solvency assessment
  • Construction/production management reviews
  • Contractor operations reviews
  • Functional performance evaluations
  • Earned contract incentives


The purpose of CPARS is to ensure that contractor performance data is appropriately assessed and that feedback regarding performance is conveyed to companies with whom the government has contracted. The CPAR can be considered a “report card” on how well a contractor is performing or has performed on an individual contract.  Once a contract is awarded, the Contracting Officer’s Representative (COR) obtains a CPARS user ID from the Program Contracting Officer (PCO).

Guide: Guidance for the Contractor Performance Assessment and Reporting System CPARS – June-2020



Every 12 months throughout the life of a contract the Assessing Official (Program Directorate/Department Head/Program Manager/Technical Code) will prepare a CPARS evaluation on contracts meeting the business sector thresholds in accordance with the applicable completion instructions as listed in the DoD CPARS Guide.  The Assessing Official is encouraged to seek input from the multi-functional acquisition team when assessing the contractor’s performance.  At a minimum, PCO input should be obtained.  Support contractors should not prepare inputs to CPARS (not even as project team members) and should not have access to CPARS.  (FAR 7.5)


After the report has been processed and reviewed, the Assessing Official will notify the contractor and provide guidance for the review process.  The contractor may review and comment on the assessment within 30 calendar days of the evaluation.  If the contractor would like a meeting to discuss the CPAR, a written request must be forwarded to the Assessing Official within seven calendar days from notification of the evaluation.
