The Kentucky rule

How Kentucky counts a lost day

Kentucky requires at least 1,062 instructional hours on at least 170 student attendance days. After an emergency a board may amend its calendar and lengthen or shorten the remaining days by 30 minutes or more, as long as the year still meets the requirement.
