A primary school in Co Wicklow has banned the use of smartphones.
St Cronan's in Bray carried out a survey in June and 91.2% of parents voted for the ban.
Basic mobile phones for calls and texts are allowed but must be switched off at all times.
The school's principal, Maeve Tierney, says there are many reasons why the decision was made.
"We have had to deal with issues of cyberbullying, we have children accessing inappropriate material, material with adult content," said Ms Tierney.
We reopen tomorrow, 29th Aug at 8.40am. Please also note that smartphones are no longer permitted in St. Cronan's following a survey in June where 91.2% of parents voted for a ban on smartphones.

"We have children engaging in very risky behaviour online as well.
"This is an issue. It's an issue for schools, it's an issue parents.
"It's an issue for schools right across the country."
The ban comes as thousands of children go back to school today.
