In my school district we have extensive guidelines regarding digital citizenship for parents, students, staff and other stakeholders. This board policy is posted for public viewing. Expectations are clearly outlined.
http://www.central-csd.org/SiteContent/Documents//board_policies//605.6R1_accept_use_separate.pdfWe deliver this information in a variety of ways. It is the norm for students and staff in our district to follow these guidelines and parents to facilitate and support all in this effort.
Responsibilities include consistent modeling and monitoring of the guidelines and revision when necessary. Violators of the guidelines are addressed individually.
