Education
Highest level of schooling
About this topic
Highest level of schooling shows the highest year of primary or secondary school completed by people aged 15 years and over. It describes school attainment rather than post-school qualifications.
This topic helps indicate educational attainment and can support analysis of access to employment, training, and services. It is best read with qualifications and other socio-economic indicators, because school completion alone does not show a person's full skill profile.
Interpretation notes
- This records the highest year of primary or secondary school completed by people aged 15 years and over.
- It is not a measure of post-school qualifications, so it should be read with non-school qualifications for full attainment.
