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.

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.
