Which of the following is NOT a type of contract a contracting officer may handle?

The reasoning behind identifying "Human resources contracts" as not being a type of contract that a contracting officer typically handles lies in the distinction between types of contracts used in federal procurement and the nature of specific agreements like human resources contracts.

Contracting officers are primarily involved in various established contracting types, including fixed-price contracts, cost-reimbursement contracts, and time-and-materials contracts. These three contract types are foundational categories in federal procurement:

• Fixed-price contracts establish a set price for the goods or services provided, providing certainty in budgeting.

• Cost-reimbursement contracts allow for payment of allowable costs incurred, plus a fee, making them suitable for projects where the costs are difficult to estimate upfront.

• Time-and-materials contracts combine aspects of both fixed-price and cost-reimbursement contracts, paying the contractor for time spent and materials used during the project.

In contrast, "Human resources contracts" typically refer to agreements related to personnel services or employment arrangements, which do not fit into these structured categories of procurement contracts. Human resources activities may be managed through different administrative channels and may involve contracts for specific personnel services rather than the procurement of goods or services as defined in contracting practices. Consequently, they are not classified alongside the traditional types of contracts with which contracting officers generally deal
