child (eldest in year) has chance to start a year 'behind' - good idea?

[DopeyDawg]

hoping to move to the English education system.

child would be one of oldest in year as mid Sept b'day.

due to the system we have been in there is a chance child could start 1 year below (Y5) which would mean would be quite a bit older than some others in class.

This chance is because moving across from Scottish system where child is sitting 1 year behind anyway. Child has dyslexia and struggles academically and gets bullied and also is young' socially but looks older physically.

Y5 would mean child could start Middle (state) school with all the others.
And not have Sats at end of 1st year in new system.
If teased about age could just say 'it's because I came from Scotland?'

any opinions on advisability of this, please?

Have it in writing from Head of Middle school now (he thinks good idea too) but might still ask for it in writing from County too.

I have a young in the year DD, and if I had this chance I would grab it with both hands.

But I'm not sure if I would if she were one of the oldest in the year.

I know someone who was moved up a year, then had to repeat Y6 (they went to a different primary for that year) as they weren't able to move up to secondary, so I'd check out, and get in writing, what would happen later on.
