We failed to apply on time for DD to attend out-of-catchment grammar school, for no particular reason except that it was a busy time and she was settling in to her new secondary school (strange variety of transfer arrangements in our area!). After the deadline she started pestering us and so we put in a late application, she was tested, achieved a very good score and as a result of the test has been placed second on the waiting list. We are appealing as we understand that once places have been offered on appeal, the waiting list becomes fairly irrelevant. She's very keen to attend, and the academic standards are much higher that those of the "satisfactory" school she now attends. Any tips for a successful appeal?
