Which responsibility is NOT associated with an ACO?

The responsibility of awarding new contracts is typically not associated with an Agency Contracting Officer (ACO). The primary role of the ACO includes ensuring that contract requirements are met, managing the execution of existing contracts, and overseeing compliance with subcontractor requirements. These responsibilities focus on monitoring and managing the ongoing obligations of contracts rather than initiating new contractual agreements.

In contrast, the tasks of complying with contract requirements and managing daily contractual activities are integral to the role of an ACO, as they ensure that contracts function smoothly according to their terms. Similarly, subcontract compliance management falls under the purview of the ACO, as it involves oversight of how subcontractors fulfill their obligations under the primary contract. Hence, awarding new contracts distinguishes itself as a responsibility handled at a different level or by specific offices tasked with procurement, making it the correct choice in this context.
