The Missouri rule

How Missouri counts a lost day

Missouri requires at least 1,044 hours of actual pupil attendance, plus 36 make-up hours built into the calendar for bad weather. A district must make up the first 36 weather hours and half of any hours beyond that, but never more than 60 make-up hours in total; anything past that is excused.
