The board is encouraged to allow community organizations to use school facilities during non-school hours. If the board allows a community organization to use school facilities during non-school hours, the board must adopt a formal policy governing the use of school facilities by community organizations during non-school hours. The policy shall prohibit such use if it interferes with any school functions or the safety of students or school personnel or affects the property or liability of the school district.
