Sask Apprenticeship and Trade Certification Commission has a similar policy of no electronic devices in the classroom. They can be outside the classroom during breaks(of which there are many). You’re allowed to have them on you, and leave class to take or make a call if you consider it important enough, just can’t have them out in the classroom. While it would have been nice sometimes to have access to network connected devices to supplement the classes, I can also understand the arguments around privacy, and distraction particularly among children/teens.
