Definition: NAICS 54 Professional, scientific, and technical services

Industries in the Professional, Scientific, and Technical Services subsector 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 subsector 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 subsector 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 subsector sell expertise. Much of the expertise requires degrees, though not in every case.

Historical comparability

Almost Comparable NAICS 54, Professional, scientific, and technical services, is close, but not quite comparable between 2002 and 1997. See the Bridge Between 2002 NAICS and 1997 NAICS for changes to constituent industries.

For comparisons with data before 1997, see the Bridge Between 1997 NAICS and 1987 SIC.

In the following table, both 1997 and 2002 data are classified by 1997 NAICS, so that the two years are comparable.
