Hello,
First time posting here so hope I don't make any faux pas! 
Looks like a lot of people here have relocated back and forth to the UK so hopefully someone has had the same challenge we are facing...
We are about to relocate to Australia for 2.5 years and we are concerned about eduction upon our return for our eldest child. The choices we make when arriving in Australia could have a knock on effect.
This is because our son is born at the end of August and is in Year 3 in the UK, and is currently the youngest in his class, aged 7.
In Australia the school year starts at the end of January so he would either go into:
- Year 3, which would mean other children in his class potentially 1.5 years older giving us concerns regarding his maturity and ability to socialise or form friendships. However he would be a term ahead...
or
- Year 2, which would mean he would go back 1.5 years and might be bored and unstimmulated potentially resulting in behavioural issues
The first thing we're trying to get our heads around is if we are only going for 2.5 years should we aim to keep him at the same level in Year 3?
Then coming back to the UK:
- If we managed to keep him in Year 3 in Australia then he would go back into the same year in the UK, hopefully in the same school with the same friends, yay!
or
- If in Australia we were forced to put him down to Year 2 then coming back he would now be a year behind and in the year below all his friends.
Our concern is that if he comes back in a lower year this will have a psychological and mental impact on him seeing his friends now in the year above?
We'd love to get your ideas if you've been in a similar situation as this conundrum has been going round and round in our head for weeks now 
Thank you!!
Lauren
