While some schools lock phones away for the entire day, others require students to place phones in containers during class. School districts implementing a locked phone policy for high school students throughout the entire school day this year include De Smet, Dupree, Ethan, Florence, Henry, Iroquois, Oglala Lakota, Rosholt and Waverly.
