Interested to hear from any current parents - how can there not be an outcry about this? With an intentionally pan-London intake where many commutes easily exceed an hour, it's the last school that should have this policy. Yet it's one of only a tiny number I can find that doesn't even permit brick phones - and it's deliberately extended to the entire school journey, making it an offense to have so much as a Nokia on hand during a transport emergency.
The head's rationale at the open evening was that there is far more danger on a smartphone these days than there is for an 11-year old crossing London by themselves. While that argument may be debatable, it breaks down completely when applied to brick phones. New guidance from DfE even recommends schools with large commuter populations to consider workarounds like handing in brick phones/keeping them switched off in their bag throughout the day. Even trackers with SOS call buttons are banned - all you're allowed is a basic tracker to see where they are (but with no means of contacting them).
