As a parent you have a legal duty to make sure that your child receives education. A child is of compulsory school age between the ages of 5 and 16 - this runs from the start of the term after a child’s 5th birthday until the last Friday in June in the school year in which they turn 16.
Schools must take an attendance register twice a day. Any absences will be recorded with a specific code depending on the type of absence. Absences fall into two main categories; authorised or unauthorised. Only the school, not parents can authorise absence. If you want leave of absence for your child you must ask for permission in advance. If your child is sick or for other unforeseen absence, you should let the school know as soon as possible.
Your child’s headteacher can only authorise leave during term time in exceptional circumstances. it is unlikely that a request for a holiday during term time will be authorised
