Existing law authorizes the governing board of a school district or its designee to regulate the possession or use of any electronic signaling device that operates through the transmission or receipt of radio waves, including, but not limited to, paging and signaling equipment, by pupils of the school district while the pupils are on campus, attending school-sponsored activities, or under the supervision or control of school district employees. Existing law explicitly authorizes the governing body of a school district, a county office of education, or a charter school to adopt a policy to limit or prohibit the use by its pupils of smartphones while the pupils are at a schoolsite or while the pupils are under the supervision and control of an employee or employees of that school district, county office of education, or charter school. This will would expand that explicit authority to also cover the use by pupils of social media, as defined, while the pupils are at a schoolsite or while the pupils are under the supervision and control of an employee or employees of that school district, county office of education, or charter school. If a local educational agency requests a pupil to voluntarily disclose or give access to electronic information, the bill would require the request to be accompanied by a written disclosure of the pupil's rights, including, among others, that the pupil can refuse, as provided.
