ACOR

An Alternate Contracting Officer's Representative is an individual formally designated in writing to support or act in place of the primary COR in overseeing contractor performance on a specific contract or order. The ACOR's responsibilities typically include monitoring technical performance, inspecting and accepting deliverables when authorized, verifying that services meet the requirements of the statement of work or performance work statement, and documenting performance issues for the contracting officer.

Unlike the contracting officer, an ACOR cannot unilaterally change contract terms or increase funding, but operates within a delegated authority defined in the designation letter and training requirements. The position provides continuity of surveillance when the primary COR is unavailable and helps maintain consistent, documented oversight.
