The DfE say…
“If over 5 academic years a pupil has attendance of 90% the child will miss a half of a school year, that’s a lot of lost education.Pupils taking unauthorised leave of absence early in the year could be categorised as persistently absent well into half term five but have perfect attendance from their return date onwards.
As parents play an essential role in supporting attendance the changes to persistent absence need to be shared with them”
