Notes and caveats
- Until 2019, Key Performance Measure 1(e) was defined as: Apparent retention rates from Year 10 to Year 12 (Indigenous school students compared to non-Indigenous school students). From 2019, Key Performance Measure 1(e) is defined as: Apparent retention rates from Year 10 to Year 12. Indigenous and non-Indigenous apparent retention rates continue to be reported as a disaggregation of the KPM.
- The apparent retention rate is an indicative measure of the number of full-time school students in a designated year level of schooling as a percentage of their respective cohort group in a base year. For example, the apparent retention rate for Year 10 – Year 12, 2018, is the number of students in Year 12 2018 as a percentage of the number of students in that cohort in Year 10 in 2016 (the base year), two years earlier. Part-time and ungraded students are not included in calculations of apparent retention rates.
- Apparent retention rates for Year 7/8 - Year 9, Year 7/8 - Year 10, Year 7/8 - Year 11 and Year 7/8 - Year 12 measure the apparent retention rate from the first year of secondary schooling (Year 7 or Year 8, depending on jurisdiction) to a later year of schooling. Up to and including 2016, the base year for these calculations was Year 8 for Queensland, South Australia and Western Australia and Year 7 for other states and territories.
- In 2015, the structure of schooling in Queensland and Western Australia changed, with Year 7 becoming the first year of secondary schooling, whereas previously it was Year 8. For those apparent retention rates using the first year of secondary education as the base year, this will progressively impact both state specific rates for Queensland and Western Australia, and national rates calculated from 2017 onwards. The base year for these rates for South Australia continues to be Year 8.
- The ABS publishes both capped apparent retention rates, which are capped at 100 per cent, and uncapped apparent retention rates. This report publishes uncapped rates.
- It is not currently possible to calculate actual retention rates. There are a number of reasons why apparent rates may differ from actual rates, why they may differ between states and territories and between school sectors, and why apparent retention rates by state and/or sector may exceed 100 per cent. These reasons include, but are not limited to:
- students progressing at a faster or slower than the expected rate of one school year/grade per year
- students changing between full-time or part-time study
- migration (interstate/international)
- students changing schools across state/territory boundaries
- students transferring between school sectors
- enrolment policies, which contribute to different age/year level structures between states and territories, and age/year level requirements for leaving school
- the availability of approved alternatives to senior schooling, which may vary across states and territories
- Categories used in tables and graphs showing "school sector" are "government", "Catholic" and "independent". In some tables, the category "total non-government" (total of Catholic and independent data) is also used.
- In Schools Australia, and in this publication, Catholic non-systemic schools are counted as Catholic rather than as independent.
- See Glossary for definition of school sector and Indigenous status and for further information on apparent retention rates and the NSSC.
