Performance Assessment Plan:

a. Monitoring Performance. During the course of the evaluation period, the COR will track Contractor performance.

The self-assessment shall be submitted not later than 5 working days after the end of each evaluation period. The self-evaluation shall not exceed 1 page per PRS element. The self-assessment shall address both the strengths and weaknesses of the Contractor's performance during the evaluation period. Where deficiencies in performance are noted, the Contractor shall describe the actions planned or taken to correct such deficiencies and avoid their recurrence. The self-assessment itself will NOT be the basis for the payment re-calculation determination.

c. COR Recommendation. The COR will consider all evaluations and any other pertinent information, including Contractor self-assessment, and will prepare a report for the Contracting Officer with findings and recommendations. The Contractor will be provided a copy of the draft findings and recommendations of the COR and will be afforded the opportunity to identify factual errors.
