There is currently an issue with the Pupil Premium files from the DfE and as a result, your file may not import into SIMS. The DfE have confirmed that they are working through this issue but have not given an exact resolution date yet. We will add more information to this post as we get it.
Please also be aware that the link to retrieve your Pupil Premium file from the DfE has changed this academic year – https://get-information-pupils.service.gov.uk/downloads
