Industries in the Professional, Scientific, and Technical Services sub-sector group establishments engaged in processes where human capital is the major input. These establishments make available the knowledge and skills of their employees, often on an assignment basis, where an individual or team is responsible for the delivery of services to the client. The individual industries of this sub-sector are defined on the basis of the particular expertise and training of the services provider.

The distinguishing feature of the Professional, Scientific, and Technical Services sub-sector is the fact that most of the industries grouped in it have production processes that are almost wholly dependent on worker skills. In most of these industries, equipment and materials are not of major importance, unlike health care, for example, where "high-tech" machines and materials are important collaborating inputs to labor skills in the production of health care. Thus, the establishments classified in this sub-sector sell expertise. Much of the expertise requires degrees, though not in every case.
