Yeah I'd miss a day or two here and there.
Forgetting vacations though, I would skip some classes for a week or two and never had a problem with tests or participation (assignments were something else entirely as I rarely did them truant or not). I found most high school classes to be pretty pointless... so much time wasted on silent reading, home room, lunch, recess etc then there were the classes, with "group work" and "in class exercises," "work on your postcard project" etc. If you actually added up the time spent with useful instruction it would probably amount to 2 hours a day and most of that would be for math lol.
If my high school experience is any indication, I would have no issues taking a kid out for weeks even, if the teacher outlined the readings and assignments. I would not expect a teacher to go out of their way so my kid could go gallivanting and if my kid struggled with school I guess I'd have to reconsider.
