The Nebraska rule

How Nebraska counts a lost day

Nebraska requires at least 1,032 instructional hours for elementary grades and 1,080 for high school. At the State Board's discretion, a district that closed for severe storms or epidemic sickness keeps its accreditation and state aid, after the board secretary files a sworn statement if fewer hours will be offered.
