About Occupation Standard Classification for Australia (OSCA)

Reference Period: 2024, Version 1.0 Released 06/12/2024

The Occupation Standard Classification for Australia (OSCA) is a systematic framework for organising, storing, and presenting occupational data. From July 2022 to December 2024, the Australian Bureau of Statistics (ABS) conducted a detailed study of the Australian and New Zealand Standard Classification of Occupations (ANZSCO). On December 6, 2024, the Australian Bureau of Statistics (ABS) published OSCA Version 1, which replaced the ANZSCO Version 2022 occupation list for usage in Australia.

The role of the Australian Bureau of Statistics (ABS) is to develop and maintain the Occupation Standard Classification for Australia (OSCA) list. The ABS uses OSCA to describe work in its statistical output, which comes from studies like the Labour Force Survey and the Census of Population and Housing. It also uses administrative data from sources like the Linked Employer-Employee Dataset. OSCA can also be used to study and figure out how the job market works. For instance, creating workforce strategies to help businesses and setting up ways to make sure there are enough skilled workers by allowing skilled migration and educational paths are two examples. These efforts are crucial for addressing skill gaps and making sure that the skills of the workforce match the needs of the business. Using what they’ve learned from OSCA, policymakers can make focused changes that help the economy grow and create more jobs for everyone in Australia.

In Australia, the term “skill level” refers to an individual’s level of proficiency or expertise in a specific task or activity. It can range from novice to expert and is frequently evaluated using performance metrics, experience, and expertise in the relevant field. It is measured operationally by considering the following dimensions:

  • the level or amount of formal education and training
  • the amount of previous experience in a related occupation
  • the amount of on-the-job training, and
  • personal attributes.

The OSCA system contains five (5) skill levels. Each skill level defines the general criteria. They do not specify particular qualifications or entry pathways. Some occupations require a specific level of formal education. For these occupations, years of experience cannot replace this requirement.
