The couple I know have adult children. I can't imagine there is a school on board. You could probably homeschool....then you would have school available. If you are buying in or leasing long term from an owner, I would certainly ask the ship management themselves rather than a bunch of us who only know people who own. Perhaps owners bring their own teacher if they need one. That's what I would do = control of curriculum, subject availablity, meeting your home countries or states requirements.....
