Cell Phones at school. Most students bring their cell phones to school. While I believe that students should carry cell phones in case of an emergency, many students travel to and from school without their parents. But, it is important for them to have a cell phone in case they need help or have an accident on the way to school or home. Parents who work may need to contact their children. For example, if parents have to work late, the student has to be told if arrangements have been made for a relative or neighbor to look after them.
