From 1st September 2013, new regulations come into force with regard to taking leave (including holidays) during term time.
As of that date, headteachers may not grant any leaves of absence during term time unless there are exceptional circumstances.
It should be noted that the revised legislation relates to all requests for leave of absence not just requests for a family holiday.
Leave of absence without permission continues to be registered on the child's attendance record as unauthorised absence and may be subject to penalties.
Further information can be obtained from the DfE website.
