Children will soon be prevented from bringing mobile phones into Dutch classrooms. Sources close to the Cabinet confirmed that schools will have until October 1 figure out how they can arrange the restriction on their own. If that fails, national rules may be introduced to restrict the use of telephones in schools. Unnamed sources also confirmed the story to ANP, after it was first reported by AD and RTL Nieuws.
Yes and no. The government strongly advised/urged school to remove phones from the classroom.
They chose to do it this way to allow schools to have their own exceptions and because legislation would take an estimated 3 years to introduce.
So far this only applies to middle school. Junior grade is still being looked at.
