Teachers cannot establish, maintain, or use a work-related website unless it is available to school administrators and the child's legal custodian, physical custodian, or legal guardian. Teachers also cannot have a nonwork-related website that allows exclusive access with a current or former student. Former student is defined as any person who was at one time a student at the school at which the teacher is employed and who is eighteen years of age or less and who has not graduated.
