The NSC considered different existing classifications with the following key principles to develop the skill classification:
- could be adapted for the Australian context
- is data driven
- would identify skills that are transferable across occupations
- is comprehensive
- identifies trending skills
- is dynamic.
Among those existing classifications, the American classification O*NET stood out with these principles.
O*NET is a rich database containing information on all American occupations through annual surveys of American workers since 2000.
To adapt O*NET data to the Australian occupation classification, we first developed a mapping system between O*NET occupations (the Standard Occupational Classifications (SOC) used in the United States) and the ANZSCO occupations (the Australian and New Zealand standard classification of occupations).
By borrowing from O*NET and mapping to ANZSCO using the concordance table, we then developed a structured skill classification, describing job requirements for the ANZSCO occupations.
