The DfE have advised the following:
How should schools record attendance?
- Where a pupil cannot attend school due to illness, as normally would happen, the pupil should be recorded as absent in the attendance register and the school will authorise the absence. Code I (Illness) should be used in this instance.
- Where a pupil is in self-isolation, in accordance with latest information and advice from Department of Health and Social Care and Public Health England, the pupil should be recorded as unable to attend due to exceptional circumstances in the attendance register. Code Y (Unable to attend due to exceptional circumstances) should be used in this instance.
If you are unsure of what attendance codes to use please contact your local authority or the DfE to confirm.
