Could you not move back home at the end of term, which will be in July? That would also give your younger son the summer holidays to get used to being back there.
I could see a situation where this could happen for non-fraudulent reasons. Higher specialist training rotations in medicine can cover a very wide area. Although there is an attempt to try to make rotations geographically sensible, to ensure adequate training opportunities for all, it isn’t always possible to give people commutes of an hour or less to their base. For example, the whole of Scotland is a deanery.
With antisocial hours working, it is not that uncommon for people to make the difficult decision of moving close to their post for a year, whilst still maintaining the cost of their actual home. Whilst the affected doctor usually lodges, and their partner has to muddle through the working week in terms of childcare, I have known whole families move, particularly when the partner isn’t working and the child not yet in school.
it’s not common, and although I haven’t seen it happen in the year that the family needs to apply for a school place, it is a perfectly plausible scenario.
I’m not sure what happens in that situation. Clearly nobody would want to get a school place 3 hours away from home, just because they happened to be working there for a year at a crucial time.
There must be other jobs with secondments etc that would cause a similar picture.
