Year 12 certification rates dataset
Notes and caveats

 

The following data, derived from data supplied to the Australian Government Department of Education and Training by state and territory Curriculum, Assessment and Certification Authorities, show Year 12 certification rates by demographic, state/territory and sex. Two types of demographic are shown: geolocation and socio-economic status (SES).

Notes and caveats

    • Certification rates are estimated by calculating the number of students who meet the requirements of a Senior Secondary Certificate or equivalent expressed as a percentage of the potential Year 12 population. The potential Year 12 population is an estimate of a single year age group which could have attended Year 12 that year, calculated as the estimated resident population (ERP) aged 15 to 19 divided by five.
    • The ABS Index of Relative Socio-Economic Disadvantage has been used to calculate socio-economic status (SES) on the basis of postcode of students' home addresses. Low SES is the average of the lowest three deciles, medium SES is the average of the middle four deciles and high SES is the average of the top three deciles.
    • The estimated resident population (ERP) data from 2011 were rebased using the 2011 ABS Census of Population and Housing. This has caused a break in the series as population estimates are now lower than they would have been if they were based on 2006 Census data. This has led to a slight increase in certification rates compared to previous years.
    • Data for Victoria from 2011 include students completing the Victorian Certificate of Education (VCE) and the Victorian Certificate of Applied Learning (VCAL) at the intermediate or senior levels. Data in previous years excluded Year 12 students completing VCAL. This forms part of the increase in certification rates since 2011.
    • In 2011 the SACE Board of South Australia introduced a new qualification listing, replacing the HESS General subjects with 'Tertiary Admissions Subjects' (TAS). Data included students at SA contact schools completing the SACE requirements and students receiving a Record of Achievement for completion of at least one full year (20 credit) Stage 2 SACE subject. Both NT and SA showed an increase in completions due to this. This has added to the increase in certification rates since 2011.
    • WA changed the pre-year one entry age in 2002 resulting in approximately half the normal intake of students for that year level. Therefore in 2014, Year 12 had significantly lower enrolments when compared to the population of the year 12 age group. For this reason, WA data for 2014 should not be compared with other years.
    • In 2013, the ABS conducted a one-off exercise to revise (recast) population estimates back to 1991. Certification rates in NSW remote areas have increased from previous years due to the improved statistical methodology. For more information, refer to the 20 June 2013 release of Australian Demographic Statistics, Feature Article 2: Recasting 20 years of ERP.
    • Victoria remote/very remote areas and South Australia outer regional/remote/very remote areas data are not available.
    • Australian Capital Territory metropolitan/major city areas includes provincial/inner regional areas.
    • There are no Tasmania major city areas, Northern Territory major city/metropolitan/inner regional areas or Australian Capital Territory outer regional/remote/very remote areas.
    • The populations in the High SES deciles of the Northern Territory and the Low SES deciles of the Australian Capital Territory are too small to give meaningful results.
    • This indicator should be interpreted with caution as:
      • assessment, reporting and criteria for obtaining a year 12 or equivalent certificate varies across jurisdictions;
      • students completing their secondary education in Technical and Further Education (TAFE) institutes are included in reporting for some jurisdictions and not in others;
      • the aggregation of all postcode locations into three SES categories – high, medium and low – means that there may be significant variation within the categories – the low category, for example, will include locations ranging from those of extreme disadvantage to those of moderate disadvantage.
