I never once did anything more than let the school know my kids would be out. Making up assignments was assumed (by me). If I wanted them out for a month, that's my call. I never asked permission, and it wasn't up to the school whether or not it was ok.Yes. The school system has a list of approved absences.
Yes. It is the responsibility of the parents to make sure their kids attend school as required by law.
Having said that, there were times when I wanted to pull my kids from school for a week in order to go on vacation. I contacted the principal and they excused the absences for my kids on the condition that they make up all missed assignments.
