How often does a contractor need to be evaluated through CPARS during a contract period?

The appropriate frequency for evaluating a contractor through the Contractor Performance Assessment Reporting System (CPARS) is primarily established to ensure that assessments are made based on the contractor’s performance throughout the contract period. Evaluations are typically conducted at the end of the contract to provide a comprehensive assessment of how well the contractor performed against the contract requirements. This end-of-contract evaluation allows for a complete and final appraisal of the contractor's performance, which can then be documented and utilized for future contracting decisions.

While ongoing assessments are valuable in some contexts, the structured approach of conducting a full evaluation at the contract's conclusion allows for a thorough review of the contractor’s achievements, challenges, and overall effectiveness, thereby fostering transparency and accountability in the procurement process.
