Standard Occupational Classification System Law and Legal Definition

The Standard Occupational Classification (SOC) System is the method or system followed by the U.S. government to classify occupations. This system was developed in an effort to build up a universal occupational classification system. Federal statistical agencies follow the SOC system to classify workers in to different occupational categories for the purpose of collecting, calculating, and disseminating data.

As of 2010, the U.S. SOC system has identified around 840 occupational categories. All workers are classified into one of these occupations, depending upon their occupations. The SOC system helps in comparing occupational data across different governmental agencies. It also serves as a platform to compare occupational data that the governmental agencies and private organizations produce. Employers who intend to set salary scales or locate a new plant, government program managers, industrial and labor relations practitioners, students, job seekers, and vocational training schools use occupational data.
