Here is further guidance if you think your child is unwell and you are not certain if they should miss school or not. Not every minor health illness means a child should need a day off.
Guidance from the NHS - Is my child too ill for school ?
Children are required to attend school from 8.45 a.m. until 3.15 p.m. If parents pick up late persistently, they will need to discuss this with the P.S.A. and then the headteacher. Office staff cannot take responsibility for children after 3.15 p.m. except where there is an exceptional circumstance.
