Methodology

Schools, pupils and their characteristics

Published: 15 June 2021

Data collection

Census collections

Schools and local authorities are required to provide the Department for Education (DfE) with a school census return (using a DfE-designed survey instrument) covering a wide range of information on the characteristics of schools and the pupils within them in January each year. Additionally, independent schools, general hospital schools and alternative provision provide (via the local authority) details on the number and characteristics of their pupils at this time.

Guidance on what is collected in each of the censuses can be found at the links below:

School Census Guidance

Independent School Census Guidance

General Hospital School Census Guidance

Alternative Provision Census Guidance

Timeliness

The proposed month of publication is announced on gov.uk at least twelve months in advance and precise dates are announced at least four weeks prior to publication. In the unlikely event of a change to the pre-announced release schedule, the change and the reasons for it would be announced.

The figures in ‘Schools, pupils and their characteristics’ are initially available internally approximately two months after the census data collection is completed and the data has been cleaned. The pre-announced publication date is chosen in order to allow enough time to produce and quality assure all the tables in the release, but ensure that the data is still current and relates to the academic year in which it was collected

Cross border movement

The main figures presented in the publication and data report geography based on where the pupil attends school, rather than where pupils live. The School Census collects further information about individual pupil residence and this data is used to produce the Cross Border Movement data. Pupils educated in independent schools are not included in this data and only figures for primary, secondary and special school pupils are published routinely.

Figures given at national or regional level are summaries of the number of pupils living in that country or region who are known to attend school in a different Local Authority (LA) in England to the one in which they live. A proportion of pupils at schools in England have resident postcodes which do not correspond to an English Local Authority area, either because the pupils live outside the boundaries of England or the postcode is not recognised. These unknown cases are denoted in the data in columns referring to country, region and la as ‘:’. The data shows the Local Authority in which these pupils are attending school. More than 99% of pupils attending state schools in England have resident postcodes indicating that they also live in a Local Authority in England.

Accuracy and reliability

For the school census return, all schools that were open on school census day, 16 January 2020, were required to submit a school census return via their local authorities. Similarly, all open registered independent schools and general hospital schools were required to submit their respective returns and all 151 local authorities were required to submit their details of their alternative provision in the alternative provision census.

For the school census and alternative provision census, data were loaded directly into the DfE bespoke data collection system; COLLECT (Collections On-Line for Learning, Education, Children and Teachers). The data passed through several phases of checking and data cleaning. The data that were loaded into COLLECT were subject to a pre-agreed series of validation checks to aid the submission of accurate data. Extensive guidance and support was provided to schools and local authorities to help them ensure the data they provide was as accurate as possible. The guidance aimed to reduce the impact of any local variations by collecting data in as consistent a format as possible, and by having extensive phases of checking and sign off

The independent and general hospital school census returns were either loaded directly into COLLECT by the schools themselves, or they submitted a paper version of the return to the department, where it was then loaded into COLLECT on their behalf. The school was then asked to check that the data had been loaded correctly into COLLECT

Consistency

From the 2019/2020 academic year publication in June 2020, the data will be disseminated via the Explore education statistics tool. In producing the data for this tool, a number of minor revisions have been made in order to make the data as accessible and transparent as possible.

Pupil counts

The ‘Total’ of all pupils can vary depending on the selections made by the user. Free school meals, language and ethnicity are not collected for independent schools, therefore any breakdowns of these statistics will not include independent schools in the ‘Total’ or denominator for any percentages.

Previously, published statistics were in some cases limited to state-funded primary, secondary and/or special schools. These school types are available for selection and consistent figures can still be produced. However, it should be noted that any ‘Total’ includes all school types available for selection, including non-maintained special schools and pupil referral units.

Class size

From 2019, the number of pupils in key stage 1 and key stage 2 classes includes those in both state-funded primary and secondary schools. In previous statistics releases, these figures did not include secondary pupils for academic years prior to 2018/19. The data included in the Explore education statistics platform includes the number of pupils in key stage 1 and key stage 2 classes in both state-funded primary and secondary schools, for all years, therefore some minor differences may be found when comparing time series.

Figures for primary or secondary only are available and can be produced using the table tool.

General hospital schools

There are 10 general hospital schools that have returned data through the general hospital schools census. These schools are included under state-funded special schools in any counts within this publication.

Funding and accountability

Data from the census are used for funding and school accountability. As the funding and accountability systems are similar for all schools it is unlikely that these cause significant bias in the data reported. As funding or accountability processes change it is possible that schools increasingly focus on ensuring certain items within the census are accurate and up to date. When such changes occur we carefully monitor the data provided by schools to try to detect changes in data caused by the changes in the funding or accountability regime. There are no planned revisions to this Statistical Publication. However, if at a later date we need to make a revision, this will comply with the Departmental revisions policy.

Disclosure control

The Code of Practice for Official Statistics requires us to take reasonable steps to ensure that our published or disseminated statistics protect confidentiality.

The data published in this release does not reveal the identity of individuals. Where there is a single pupil with a particular characteristic, prior knowledge of that circumstance would be required to determine which pupil it is. We deliberately avoid crossing multiple characteristics in this release, in order to ensure that knowing one piece of information about a pupil would not reveal any further information. By doing this, we can avoid suppression or rounding which means that all published tables at local or national level should be calculable from the published underlying school level data. This in turn means that the practical utility of the statistics, particularly the school level data, is not constrained.

Coverage

The submission of the school census returns, including a set of named pupil records, is a statutory requirement on state-funded schools under Section 537A of the Education Act 1996. A census return is required for all schools in January each year. This is to ensure schools provide pupil level data in a consistent manner that can support comparisons.

Completion of the school level annual school census by registered independent schools is a statutory requirement under the Education (Independent Educational Provision in England) (Provision of Information) Regulations 2010.

The submission of the alternative provision census returns, including a named set of pupil records, is a statutory requirement on alternative provision providers under the Education (Information about Children in Alternative Provision) (England) Regulations 2007.

All data is as reported for school census day, 16 January 2020.
