Known Issues
The documents on this page hold details of errors or problems which affect the ILR datasets supplied by the Data Service. These include errors with the calculation of derived variables, systematic incorrect recording of data by providers, and other data quality issues.
For each collection type and academic year there is a document describing the outstanding known issues affecting the latest available dataset, and a document describing all the known issues that have affected previous datasets, including those that have been resolved.
The terminology used to identify datasets within the known issues document is:
Collection Name, collection number, date dataset prepared.
For example,
Employer Responsive W01 dataset prepared on 07/09/2009
Please note that where known issues are discovered after a dataset is published the known issues document will be update to reflect this.
