If you haven’t run into it, the keyword you're looking for is "world schooling". I have some friends who home school and they decided to travel while doing it. They move to a location for a few months and use a "world school" in the new location. The school is global and has a ton of branches in different countries so there is continuity in philosophy and assessment and whether the kids are curriculum-wise.
