An occupational code assignment (OCA) is a process established to help occupational information users relate a job title or occupational specialty to an O*NET-SOC occupation. The Occupational Information Network (O*NET) is a Standard Occupational Classification (SOC) based system. Businesses, training and educational institutions, labor and occupational organizations, and professional associations can use the OCA process to determine if a job title or occupational specialty is recognized within the O*NET-SOC system and the U.S. labor market.
The information gathered during the OCA process:
- leads to code assignments for customers,
- helps update the O*NET lay titles database, and
- is considered during the O*NET-SOC occupational classification review and development.
