After initially telling schools they must send students home if they refuse to wear masks indoors, California public health officials abruptly changed course and said districts will be able to decide how to enforce the mask mandate. While California says fully vaccinated people don't have to wear masks in most public places, the state has different rules for schools. Last week, officials said students and staff at schools must continue to wear masks indoors at all times, even if they are fully vaccinated. California officials released details of those new rules Monday afternoon, including a requirement that schools "must exclude students from campus if they are not exempt from wearing a face covering under (the rules) and refuse to wear one provided by the school."
