The Illinois rule

How Illinois counts a lost day

Illinois requires a calendar of at least 185 days to guarantee 176 days of actual student attendance, each of at least 5 clock hours. The extra calendar days are emergency days used first; after they are gone, the State Superintendent may excuse days lost to an act of God or a hazard beyond the district's control without cutting state aid.
