I can see why you might view this as unfair, but if you were in the situation where your child could not attend on the day would u not expect to be offered an alternative?
I think 3 days is reasonable, SGS offer an alternate date in November, so an extra month of prep if that's how u view it.
Dids- I agree that an alternative should be offered and I do completely understand that if a child is ill or they are Jewish that they cannot sit the exam on the Saturday.
But the Saturday is absolutely manic, with 1000+ pupils all turning up at once. It must be so daunting for the boys, especially as they often have to sit the exam in a room full of strangers. So I do think that it must be an advantage for the children to sit the exam on an alternative date with their friends- that is not the fault of the child/ parent, it is the fault of the school.
I think the only fair solution would be to split the numbers in half- 600 should sit on the Saturday and the other 600 should sit on another date.
I am going to write to the school to request this and suggest that others could do the same?
Incidentally, last year a child at DS's school missed the exam on Saturday as he was 'ill' and the mother was frantically asking all the other Mothers exam question details!
