I found an interesting comment for those who are thinking about homeschooling, or who are homeschooling, but who would like their kids to go back to school at some stage in the UK or a UK system school overseas. I can’t vouch for its veracity. http://uaehomeschool.wordpress.com/#comment-1953

Hello. I home-educate in England, but came across this site while reading up on home-ed elsewhere, and thought of a few things which might be useful to note here.
Those of you who come from the UK, or who are considering studying towards UK public exams, might find the HE-Exams yahoogroup helpful. It’s for home educators who want to find out about UK formal qualifications, and there are a few members who are expats. Many members have children studying for International GCSEs (IGCSEs), both in the UK and for expats. IGCSEs are often the only practical option for us in the UK because of the coursework element of standard GCSEs. It’s OK though – the exams are well regarded and recognised by universities etc..
The address of the HE-Exams group is http://groups.yahoo.com/group/HE-Exams-GCSE-A_AS_Levels-OU-Others .
You do not need to do a distance learning course to pass IGCSEs. You can enter as a private candidate, and many of us do a do-it-yourself approach, where our children work through the set textbook, read around the subject themselves, and do lots of practice exam papers. The parent does not need to be an expert in the subject, though this approach is easier for some subjects than others. For maths and sciences, for instance, the textbooks teach the child exactly what’s needed for the syllabus and have plenty of exercises to work through, and the answers are provided so you or they can mark the work. When it comes to time to do practice exam papers, you can download these free online from the exam board ( Edexcel International GCSEs, and CIE IGCSEs are popular), and likewise the marking scheme and the examiners’ reports, with their comments and tips. Sometimes it’s not clear what more the correspondence courses really offer for the money; I think parents pay for peace of mind, but don’t always get it anyway!
I saw that some comments mentioned Oxford Open Learning/ Oxford Homeschool etc.. You might like to discuss this on the HE-Exams list, as other members have mixed experiences of this provider, and others. Another option which you might have heard of is the internet school – Interhigh and Briteschool are the UK ones I’ve heard most of, with most positive comments for Interhigh. Students ‘sign in’ for online lessons at 9.30 AM UK time, finishing around 12.00, so maybe that could be manageable with the time difference? It would just be afternoon school for you guys, and morning school for those here! Seehttp://www.interhigh.co.uk/
For those thinking of returning to the UK system at some point, maybe you don’t need to worry too much. Many home-ed kids in the UK go to school at some point, often without having done much formal studying beforehand, and they generally fit in well. Certainly there is no need to show proof of having followed any particular curriculum or programme, and schools in the UK will not make you re-do years. When home-ed children go to school here, they start school in the appropriate year for their age, and invariably they soon catch up. If you are already in the GCSE years (usually 15-16) and need GCSEs for further or higher education then you can take the usual minimum requirement of five or so in a single year, to give you access to sixth form study.
Good luck, all!
Homeschooling Middle East 
This is good to know! I know so many parents who choose their children’s schools based on what will ‘fit’ when they go back.
I know! And yet, we have no idea where ‘back’ is, where ‘home’ is, so thus far I’m not following any curriculum and we’ll see how it goes until Edward’s about 15 and then start thinking about the likely geographic location of his first foray into adulthood and whether this involved higher education or some other further education that would require us to change what we’re doing. This really phases people! Just today, I met someone who asked which school my kids went to. When I said I home educated, they looked startled but quickly regained their composure and asked, ‘But which curriculum are you following, British or American?’ When I said I make up my own she looked at me in amazement and I could see her thinking, “She seemed so nice and yet now I think she’s completely crazy and her kids must be really odd”. Aaaah. Well, we may nor may not get a chance to change her mind, but it sure isn’t top of my list of life priorities!!
