Department of Defense
Contracting Officer Warranting
Program Model
Considerations for Developing an
Individualized Organizational Approach

Preface
Contracting Officer Warranting Program Model, Considerations for Developing an
Individualized Organizational Approach, was developed to assist the military departments and
defense agencies, defense field activities, and their subordinate organizations, in reviewing and
assessing how they select, appoint and terminate the responsibilities of contracting officers.
“Warranting” and “Warrant” are terms of art as they apply to contracting officer authority that
are used by workforce members in the Contracting Career Field. The proper terms, going back
to the Armed Services Procurement Regulation (ASPR) 1-405 Selection, Appointment, and
Termination of Appointment of Contracting Officers, are “Appointment” and “Certificate of
Appointment.” Under the ASPR, contracting officers were appointed using a DD Form 1539,
Certificate of Appointment. Now, under the Federal Acquisition Regulation (FAR), contracting
officers are appointed using a SF 1402 Certificate of Appointment. This Model uses the terms
selection, appointment, and termination as well as the terms warranting and warrant.

Job Description of Warranted Contracting Officer for Federal Government

For both large and small companies, entering into contracts is an integral part of the business process. Business contracts cover everything from purchase orders to employee policies and legal issues. The federal government and its numerous agencies also enter into contracts, utilizing warranted contracting officers to write, evaluate, sign and terminate contracts. Each agency head appoints a contracting officer, also called a CO, through a formal written nomination. Department of Defense agencies refer to contracting officers as KOs rather than COs to avoid confusing them with commanding officers.

Types of Contracting Officers
Depending on the government agency, more than one person can fill the contracting officer position. Some agencies employ different types of contracting officers, who each fulfill a different role in the contract process. For example, the procuring contracting officer writes the contract, looks for providers who can fulfill the contract and awards the contract to the winning party. The administrative contracting officer monitors the contact once it is awarded, making sure all parties adhere to the agreement. A termination contracting officer takes care to end a contract and, if needed, negotiate early termination details. A CO also receives classification in Level I, II or III depending on his experience and training. The classification level indicates the dollar amount of contracts he can work with.

Experience and Education
A CO must have a minimum number of years of experience in government contracting and administration or commercial purchasing. A Level I CO needs a year of experience, Level II COs need two years of experience and a Level III CO needs three years. Some agencies require the CO to have 24 credit hours in business-related courses like accounting, finance, law, contracts, purchasing, economics, marketing and management. In some agencies, department heads can automatically assume the duties of a CO because of the nature of their positions. For example, the Federal Highway Administration allows the executive director and the associate administrator for administration to have contracting authority.

Main Job Duties
As the job title suggests, a warranted contracting officer has the authority from the federal government to enter into any contracts on behalf of that government agency. The warranted portion of the job title indicates that the CO has the proper appointments and has received a warrant to work with contracts for that agency. Many government employees have permission to spend federal funds but only a CO can spend over the purchase maximums set up the government. This means a CO can spend over $3,000 on goods, $2,500 on services and $2,000 for construction. If a CO cannot perform all his duties, he can bring on team members to help complete the work. These non-warranted government employees must complete a training course and act as the liaison between the CO and the contractor.

Training Requirements
Before obtaining a warrant, the CO must complete specialized training. The exact training courses vary depending on the agency and provide knowledge specific to each agency. Each CO also receives on-the-job training to supplement the training courses. Once a CO receives a warrant, he must take steps to maintain that warrant by completing a certain number continuing education credits every few years, typically every one to three years depending on the agency.
