Which of the following is NOT a responsibility of a QPA?

The role of a Qualified Purchasing Agent (QPA) primarily focuses on the procurement process and related responsibilities within public agencies. This includes tasks such as managing public bidding processes, ensuring compliance with state procurement laws, and monitoring vendor performance. Each of these responsibilities is integral to the QPA's role in ensuring that purchases are conducted in accordance with established legal and ethical standards.

Setting tax rates for local governments, on the other hand, falls outside the scope of a QPA's responsibilities. Tax rate decisions are typically made by government officials or bodies responsible for fiscal policy and budgeting. Therefore, it correctly identifies that this is not within the purview of a QPA, distinguishing it from duties that involve procurement and vendor management.
