Seems to be pretty consistent for public schools, but the current school district is the worst so far. The last one (in another state) was 5 minutes between classes instead of 4 minutes, and 30 minutes for lunch instead of 20. Parent input does have some effect - the lunch time at the previous school had been 20 minutes as well, but parents complained because the kids needed more time to eat the new healthier lunches. (It takes longer to chew fresh produce than canned.) The school's argument against longer breaks between classes has been that more time leads to more drama and problems in the hallways, and there isn't enough staff to monitor all of them.
