Post-collection outputs
ILR post-collection outputs
After a provider has submitted final individualised data to the Department of Education (DfE), we create files called post-collection outputs.
These outputs are released on the OfS portal.
The target audience for this information is registered providers that make ILR returns.
For all post-collection outputs, we use derived fields to determine whether to include a student in an output population, such as the HESES population.
We provide a CSV file with each output that contains individualised student data. For each record, we show the value of every derived field and the data that we have used to calculate them. We also provide a technical document and rebuild instructions for each output. These specify how derived fields have been calculated and how to filter individualised student data using our derived fields to find students included in aggregated data.

Reconciliation exercise HESES24 comparisonThe HESES24 comparison outputs are a summary workbook which compares HESES24 data to HESES24 data recreated using the 2024-25 ILR data and an individualised file. |
Field mapping
The individualised data files available through the 2024-25 post-collection outputs use a new field naming convention compared with previous years. We have produced a mapping of old field names to the new ones for 2024-25.
