Affiliation (of school)
Affiliation categorises schools and their enrolments and refers to the systems that administer their operation. The affiliation classification has two broad categories, government and non-government.
In this product, the subcategories of non-government affiliation are reported as either Catholic (systemic and non-systemic) or independent (Anglican schools and other schools which have associations with religious or secular bodies or are entirely independent).
Ancillary education establishment
An ancillary education establishment is defined as an establishment which satisfies all of the following criteria:
- its major activity is the provision of aspects of full-time day primary, secondary or special school education to students supplementary to that provided by schools, and
- it has attached to it (possibly on a part-time basis) at least one permanent teacher or another supervisory person, and
- students from more than one school may undertake education at it.
Examples include:
- hospital and prison schools (those not classified as special schools)
- schools of the air which do not have officially recognised student enrolments (although students may be supervised with work programs from their 'home school' or a distance education school)
- an education unit attached to a museum or art gallery
- a work experience, music or computing centre, etc.
Apparent rates
Rates in this product are termed ‘apparent’ as they are calculated using aggregate student data and have been developed to provide indicative measurements of student engagement in secondary education.
The term 'apparent' is used to refer to all rates in this product that are not the 'actual' rate that would result from direct measurement of the movement of each individual student. The calculation of actual rates is not currently possible due to the varied levels of detail in data provided to the ABS.
Rates are calculated using the total reported cohort populations in a selected jurisdiction at a selected year either as a percentage of the total ERP or as a percentage of the population for the cohort in an earlier year
There are a number of reasons why apparent rates may generate results that differ from actual rates. These reasons include, but are not limited to:
- students progressing at a faster or slower rate than expected (one year level each calendar year)
- students changing between full-time or part-time study
- migration (interstate/international)
- inter-sector (affiliation) transfer
- enrolment policies (which contribute to different age/year level structures between states and territories)
- students who attend school in a state/territory different to that in which they live
- a different reference period used in calculating the ERP (30 June) verses that used as the reference in the school system (1 August), and
- the children of diplomats, short term international exchange students and possible other anomalies, where students are counted in school enrolments but not in the ERP.
Such scenarios may also lead to apparent rates that are greater than 100%. From 2015 onwards, the ABS released rates tables in two formats, one with rates exceeding 100% capped to a maximum value of 100%, and one where rates exceeding 100% continue to be reported as the raw calculated value (uncapped). Rates that are capped at 100% are recommended for use as the authoritative measures of student progression, while uncapped rates tables may be more suitable for specific purposes such as undertaking time series analysis of the data or examining movements in underlying student populations.
The formulae and methodology used for the calculation of school participation rates, apparent continuation rates and apparent progression rates are available in the Research Paper: Deriving Measures of Engagement in Secondary Education from the National Schools Statistics Collection published in December 2006.
Population data is available from National, state and territory population, June 2023
Apparent continuation rate
This statistic is an indicative measure of the proportion of a single year age group of students (full-time and part-time) who have continued from one calendar year to the next. It can be expressed as the school participation rate of an age cohort in one calendar year as a percentage of the school participation rate of the same cohort in the previous year.
For example, an apparent continuation rate for students aged 15 turning 16 would measure the proportion of 15 year old school students that were still at school 12 months later.
Apparent continuation rates can be calculated for any age cohort with a specific characteristic such as all students of a given sex or in a given state/territory as long as a count of the total population with that age and characteristic is available.
Apparent continuation rates include both full-time and part-time students and are adjusted to factor in changes in the population.
Apparent retention rate
This statistic is an indicative measure of the proportion of a cohort of full-time or full-time equivalent (FTE) students that move from one grade to the next based on an expected rate of progression of one grade per year. For example, an apparent retention rate for Years 10 to 12 in 2023 would measure the proportion of Year 10 students in 2021 that had remained in the schooling system until Year 12 in 2023.
The year level of commencement of secondary school varies across states and territories and over time. Rates that use the year level of commencement of secondary school as the base may use a different base for each state and territory to account for differences in schooling structures. Despite this, these rates are comparable as the cohorts are retrospective to the year level of schooling and calendar year from which the rate is calculated. These variations are incorporated into the calculation of rates at the Australia level.
It is not unusual for rates in the ACT to exceed 100% by large amounts. This is mainly due to the enrolment of students in ACT schools who are not usual residents of the ACT, but who live in surrounding New South Wales regions. As a result of the small ACT population, this has a larger effect on the ACT rates than the NSW rates. This is referred to as cross-border enrolment
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. In order to maintain cohort continuity in this table, Year 8 is the commencement of secondary schooling for these two states for 2015 and 2016.
In 2022, Year 7 became the first year of secondary schooling for all remaining South Australian government and non-government schools. This completed the transition to Year 7 secondary schooling for all South Australian schools. To maintain cohort continuity in this table, Year 8 is the commencement of secondary schooling for South Australia.
Estimated resident population (ERP)
The ERP is an estimate of the population of Australia, based on data from the five-yearly ABS Census of Population and Housing, and is updated quarterly using information on births, deaths, and overseas and internal migration provided by state, territory and Australian Government departments. See National, state and territory population, June 2023 for further details. Further information is available on how this series is used in Schools, 2023, under Data release within the Methodology.
Full-time student
This is based on the minimum workload required to ensure that a student could complete a given year level in a single calendar year. The prescribed workload may vary between states and territories and between year levels.
Full-time equivalent (FTE) students
The full-time equivalent value is a measure used to indicate the number of students based on their total workload undertaken, as a proportion of a full-time workload. For example, a full-time equivalent student workload has a value of 1.0.
Students undertaking a workload less than full-time, have their full-time equivalent value calculated on the basis of the proportion of time spent on in-scope activities compared with students that would be considered full-time. All full-time equivalent values are rounded to one decimal place.
Full-time equivalent (FTE) teaching staff
The full-time equivalent value is a measure used to indicate the level of staffing resources. Staff who are employed full-time and engaged solely on activities which fall within the scope of this collection have a full-time equivalent value of 1.0.
Staff not employed on a full-time basis, and/or engaged in a combination of in-scope and out-of-scope activities, have their full-time equivalent value calculated on the basis of the proportion of time spent on in-scope activities compared with staff that would be considered full-time. All full-time equivalent values are rounded to one decimal place.
Full-time equivalent (FTE) student/teaching staff ratios
Full-time equivalent student/teaching staff ratios are calculated by dividing the full-time equivalent student figure by the full-time equivalent teaching staff figure. Student/teaching staff ratios are an indicator of the level of staffing resources used and should not be used as a measure of class size. They do not take account of teacher aides and other non-teaching staff who may also assist in the delivery of school education.
Some states and territories are not able to calculate full-time equivalent values on a time-spent basis for all staff functions, but instead use wages paid as a fraction of the full-time pay rate, or a resource allocation-based formula. Some also use a pro-rata formula based on student or staff numbers to estimate aggregate full-time equivalents for some categories of staff. This includes staff at combined schools who are allocated to either primary or secondary.
Indigenous status
Students are classified as being of Aboriginal and Torres Strait Islander origin based on information provided by the student, or their parent/guardian, on the school enrolment form.
National Schools Statistics Collection (NSSC)
The NSSC is a collection of data on students, schools, and staff involved in the provision or administration of primary and secondary education, in government and non-government schools, for all Australian states and territories. A statistical summary of the results of the NSSC is the subject of this ABS publication.
Part-time student
A part-time student is one who undertakes a workload less than that specified as full-time. The full-time equivalent value of a part-time student is calculated by dividing the student's workload by that which is considered to be the minimum workload for a full-time student by that state or territory. The minimum workload for a full-time student is that which would ensure the student could complete a given year level in a single calendar year.
Methods for estimating the full-time equivalent value of part-time students vary between states and territories due to different policy and administrative arrangements.
Remoteness area
Remoteness areas divide Australia and the states and territories into five classes of remoteness on the basis of their relative access to services.
The Australian Statistical Geography Standard (ASGS) Remoteness Structure defines these remoteness classes as:
- major cities of Australia
- inner regional Australia
- outer regional Australia
- remote Australia
- very remote Australia
For more information please refer to the online publication: Australian Statistical Geography Standard (ASGS): Edition 3 - Remoteness Structure.
For the 2023 Schools collection, data have been classified to the 2021 ASGS standard. The ASGS is based on results from the 2021 Census.
School
A school is an education establishment which satisfies all of the following criteria:
- its major activity is the provision of full-time day primary or secondary education or the provision of primary or secondary distance education
- it is headed by a principal (or equivalent) responsible for its internal operation
- it is possible for students to enrol for a minimum of four continuous weeks, excluding breaks for school vacations.
The term 'school' in this product includes schools in institutions and hospitals, mission schools and similar establishments.
The term 'school' in this product excludes preschools, early learning centres or centre based day care, senior technical and agricultural colleges, evening schools, continuation classes and institutions such as business or coaching colleges.
Multi-campus arrangements are counted as one school. Changes to school counts in this product can occur when multiple schools amalgamate into a single multi-campus school, or multi-campus schools divide into separate schools.
School participation rate
This is a measure of the number of school students of a particular age expressed as a proportion of the Estimated Resident Population (ERP) of the same age. It indicates the proportion of the population by age enrolled at school.
Rates in the Australian Capital Territory may exceed 100% by large amounts. This is mainly due to the enrolment of students in Australian Capital Territory schools who are not usual residents of the Australian Capital Territory, but who live in surrounding New South Wales regions. This is referred to as cross-border enrolment.
Non-participation in school education is not included in this product as it cannot be accurately calculated from the data supplied.
Sex
In 2023, there were 2,560 students whose sex was reported as neither male nor female. However, not all providers reported on this basis, therefore, this number does not reflect the total number of Australian school students who identify as neither male nor female.
In order to protect the confidentiality of these students the ABS has randomly assigned them to have either a male or female status. There were 88 records where sex was reported as not stated/inadequately described. These students were also randomly assigned to have either a male or female status.
There were a small number of staff from the government and non-government school sectors whose sex was reported as neither male nor female.
In order to protect the confidentiality of these individuals the ABS has randomly assigned them either a male or female status. The ABS will review this approach as input data quality improves.
In addition, most providers supply gender data, rather than biological sex, for this classification.
Special school
A special school satisfies the definition of a school and enrols students with one or more of the following characteristics:
- mental or physical disability or impairment
- slow learning ability
- social or emotional problems
- in custody, on remand or in hospital.
Special schools include special assistance schools, as defined under the Australian Education Act, 2013. These are non-government schools that are:
- likely to be recognised by the state minister as a special assistance school, and
- primarily established to cater for students with social, emotional or behavioural difficulties.
Staff
Staff are persons engaged in the administration and/or provision of day primary, secondary or special school education, or primary or secondary education by distance education at in-scope education establishments.
The reporting of staff is split into two broad categories, In-school staff and out-of-school staff. In-school staff spend the majority of their time actively engaged in duties at one or more schools or ancillary education establishments. Out-of-school staff consists of executive staff and staff not generally active in schools or ancillary education establishments. Each of these is further categorised by major function, as determined by the duties performed.
Staff not employed on a full-time basis have their full-time equivalent value calculated on the basis of the proportion of time spent on in-scope activities compared with staff that would be considered full-time.
Staff absent from a position for a period of less than four continuous weeks, as at the census date, are included. Staff who have been absent from a position for a period of four or more continuous weeks are excluded. Replacement staff are included if they occupied the position for four or more continuous weeks.
Included in the definition of staff are:
- staff teaching evening secondary students attending secondary colleges
- staff paid from school grant payments
- staff employed under various government sponsored employment schemes.
Excluded from the definitions of staff are:
- persons not under the control of the director-general (or equivalent), e.g. nurses or therapists working for the state or territory department of health (or equivalent)
- persons responsible to a state, territory or Commonwealth minister of education but not to the director-general (or equivalent)
- persons under the control of the director-general (or equivalent) who satisfy one or more of the following criteria:
- are cleaners, whether salaried or employed on contract
- are involved in the management and/or maintenance of boarding or hostel facilities for students
- are paid from privately raised funds
- have been occupying, or expect to be occupying, a position for a period of less than four continuous weeks at the census date, and/or
- are persons replacing those who are temporarily absent.
Student
A student is a person who, as at census date, is formally enrolled in a school and active in a primary, secondary and/or special education program at that school. Students may be enrolled at more than one school, however jurisdictions employ strategies which ensure that, as far as possible, such students are reported only once in this collection.
Persons not present at a school on the census date are included if they were expected to be absent for less than four continuous weeks.
Student participation in vocational education or training programs in schools, school-based apprenticeships or traineeships, work placements or tertiary extension studies, or a combination of such programs as part of the student’s school enrolment, is in scope for the NSSC. The workload of these subjects/programs (which may take place outside the school premises) is included in a student’s aggregate workload to determine whether a student is classified as full-time or part-time, and in calculating the full-time equivalent for part-time students. The total workload recorded is capped at 1.00 full-time equivalent value.
Student to teaching staff ratio
Student to teaching staff ratio is defined as the number of students to one teacher. These figures are not indicative of class sizes.
Teaching staff
Teaching staff are defined as those who spend the majority of their time in contact with students. They support students either by direct class contact or on an individual basis, and are engaged to impart school curriculum.
For the purposes of this product, teaching staff also includes principals, deputy principals, campus principals and senior teachers mainly involved in administration. Teacher aides and assistants, and specialist support staff are excluded, except assistant teachers working in homeland learning centres and community schools in the Northern Territory.
Year level and school level
Year level of education comprises Pre-Year 1 through to Year 12, including ungraded primary and ungraded secondary.
School level comprises primary and secondary.
