Answer: 1 year
Explanation: According to the Defence Federal Acquisition Regulation under 237.106, personal service contracts that apply to consulting or expert services will be limited to one year. However this will only apply to duties that are temporary (limited to 1 year, or 12 months), or non cumulative days (needs to be 130 days or more that are broken up within a year). During this time the officer contracting the service will enter into a contract, make an order, or exercise options for various services that do not exceed 1 year.
