The facts. DS was born November 2010, due to start school September 2015. We were living in Islington, regular congregation members of a church that was a feeder for a good CofE primary. DH had an amazing offer from his work to come and spend 2 years in the US starting a branch of the office. He accepted, and we were due to move in December 2012, but visas took longer to sort out than expected and we finally arrived over here last March. This means that if DH fulfills his 24 month contract, we won't arrive back in the UK until March 2015... 2 months after we need to apply for DS's school place.
From what I gather, Islington would be obliged to provide a school place under these circumstances, but we wouldn't have any say as to which school it is at.
Now DH thinks it is likely that he'll be asked to stay longer than 24 months, so we will potentially be in the US until 2016 and then facing coming back to Islington and trying to get DS into Reception part way through the school year, once again at the mercy of Islington council. He also thinks that if he told his employers that he needed come back early so that we could be in the borough for January 2014 then they would be understanding.
The problem is that we just don't know how important it will be! With hindsight, we really should have done more research into Primary schools in the area but DS was only just 2 when we left and school seemed so far off. Does anyone have any experience with moving to a London borough (Islington in particular) after the applications deadline of part-way through a school year? Would we be totally irresponsible to stay here in the US and leave things to chance when we return? DS is our PFB so we have no previous experience of the whole school admissions process.
