DS1 is in Y7 at High School. His Dad is getting married this year during term time and, obviously, wants DS1 to be there. School have refused the leave of absence request and stated that they expect DS1 to be in attendance on the days he was due to be away (it's a destination wedding so not something I can change, alter or even adapt to suit school; the actual wedding is on a week day and DS1 would be missing the whole of the last week of summer term).
So as not to drip feed DS1 has great attendance, is achieving well and all homework is on time and never gets into trouble. He also has ASD and can suffer from Anxiety at times and has been particularly anxious about being able to attend the wedding.
Am I able to appeal school's decision and challenge this? It seems awfully unfair that they've refused an application for a wedding of an immediate family member; being part of his Dad's wedding is a huge thing for DS1 and I can't see another way through this; he has to go to the wedding, he has to be there as it's his family.
Would it be U to challenge school's decision or is it best to leave it as unauthorised absence and just take the hit when they fine DH and I (they've written to us separately to advise that we'll be fined if he isn't in school on those dates)?
