The School Code (Citation 105 ILCS 5/10-19) requires each public school district in the State of Illinois to annually prepare a proposed school calendar consisting of a minimum of 185 days to insure 176 days of attendance.

Regional Superintendents are charged with reviewing and approving all public school calendars submitted by public school districts. Per Section 10-19 of the Illinois School Code, the calendar and any changes must be submitted and approved prior to the calendar or change taking effect.
