Nicola Shier, a teacher and tutor at Les Murier School, said pupils are already not permitted to have phones at the site.
Discussing having a blanket ban across Guernsey’s schools, she said: “I think it would just be an extra step to stop children bringing them into schools.”
Deputy Tom Rylatt also attended the event and said he was still at school when more pupils started getting smartphones.
He said a ban would be a bold decision but could help “protect mental health”.
“It’s not going to be easy and might be a bit painful, but my hope is by taking difficult decisions now, in 10 or 15 years time it becomes the norm and our children and students will be better for it,” Rylatt added.
Ahead of the survey launch in Guernsey, Education, Sport & Culture Committee President Paul Montague said the committee wanted the island’s schools to become “smartphone-free”.
“The issue of smartphone usage on children and young people continues to raise international, national and local concern,” he told deputies in February.
