Student number data

The Office for Students calculates student numbers for various regulatory purposes. These include setting OfS registration fees and assessing applications for degree awarding powers and university title.

We consulted on our approach to calculating student numbers in autumn 2018. View our response to the consultation.

This page contains technical information about the detailed method behind student number calculations. It is intended primarily for those who are familiar with the individualised student data we use, and who may be interested in understanding or recreating our calculations.

The algorithms applied to the 2019-20 Higher Education Statistics Agency (HESA) student record, HESA student alternative record and Individualised Learner Record (ILR) data, in order to determine a provider’s higher education and further education student numbers.

Technical document update

This technical document was updated in February 2021 to correct the conditions in the SNQUALHOURS, SNHESTULOADCASE and SNFESTULOADCASE algorithms.

The SNQUALHOURS algorithm has been updated to treat 0 the same as missing when using the raw data fields TOTAL QUALIFICATION TIME, MAXIMUM GUIDED LEARNING HOURS and TOTAL CREDITS to calculate the total hours a course is expected to take (SNQUALHOURS).

The SNHESTULOADCASE algorithm has been updated to include SNLEVEL = HE as a condition for the value 4.

The SNFESTULOADCASE algorithm has been updated to include SNLEVEL = FE as a condition for the value 5.

The algorithms applied to HESA student record, HESA alternative provider student record and ILR data, to determine a provider’s higher education and further education student numbers.

This technical document was updated in September 2020 to correct the wording for the SNAYDAYSSTUDIED algorithm. This previously said that SNAYDAYSSTUDIED was the difference in the number of days between SNENDDATE and either 1 August 20Y1 or LEARNSTARTDATE, whichever is earlier. This has been corrected to say whichever is later.

Methodology and technical documents from previous years can be found in our student numbers data and documentation archive.
